We study a drilling machine on a magnetic levitation

Processing complex and large structures by drilling is often impossible on traditional machines. To solve this problem, you can use an alternative option - a drilling machine with a magnetic sole.

Design features of machines with magnetic soles

Portable model with magnetic platform

The main difference between this type of equipment and conventional drilling machines is the layout. They do not have a traditional stationary platform, but use a magnetic base instead.

It is designed to fix the installation on the surface of a metal workpiece or part. Moreover, the orientation of the equipment can be different: horizontal, vertical or inclined. It all depends on the configuration of the product.

Structurally, all magnetic drilling machines must have the following components:

• magnetic base, also known as a mounting unit. Designed to fix the installation on the surface of a metal workpiece. It is an electromagnet that can be activated and deactivated by the user;
• Column. Serves as a support for mounting other equipment components. In some models, a block with a drilling head and an electric motor can move along it;
• drill block. It consists of an electric motor and a spindle head on which the drill chuck is attached. Depending on the configuration, the latter can only move in height or have a rotating mechanism for drilling at an angle.

Additionally, a coolant supply system can be installed. This function is necessary to increase the quality of processing. During the drilling process, the tool and material heat up. Subsequently, chips may stick to the cutting part of the drill, which will lead to its failure.

Most models of machines with a magnetic base are designed to be connected to an electrical outlet. But in some cases it is more convenient to use battery-powered equipment. It must be remembered that its power will be lower than that of conventional machines.

Application specifics

Drilling a tubular structure

The scope of application of this type of equipment is wide. Magnetic machines with a similar base have maximum mobility and can be installed on any metal surface. Thanks to their well-thought-out layout and high performance, they are used for drilling work in shipbuilding, in the construction of bridges and similar massive steel structures.

But despite the apparent versatility, you need to know certain operating rules. First of all, this applies to the base material on which the drilling machine on a magnetic support will be installed. The reliability of the clamp is ensured by the electromagnetic field. Therefore, the base must have ferromagnetic properties. If this condition is not met, you can install an auxiliary steel plate mounted on the workpiece.

Considering these qualities of the equipment, magnetic drilling machines can be used to perform the following operations:

• drilling;
• drilling and countersinking;
• thread cutting;
• milling. But only if the cartridge is designed for such loads.

To ensure the stability of the structure, in addition to the magnetic base, mechanical types of fastening can be used. This is relevant when installing on round pipes or complex metal structure components. The adapter is attached to the pad without interfering with the contact of the magnet with the metal surface.

When choosing a model, it should be taken into account that magnetic machines must have increased protection from moisture. This is due to the specific nature of outdoor use.

Classifications of drilling machines

To determine the optimal type of magnetic levitation drilling machine, it is necessary to take into account its technical and operational qualities. Despite its relatively small size, this type of equipment can have wide functionality.

There is no generally accepted classification of magnetic base machines. Therefore, before purchasing, it is recommended to do a comparative analysis of the proposed models. The determining parameter is the operating conditions of the equipment. They must correspond to the characteristics of the magnetic machine.

Based on this condition, the following equipment parameters can be distinguished:

• drill feed – manual or automatic. The second option is used when it is impossible to manually carry out the drilling process. The parameters of the machine with a magnetic base are pre-set, and then, after installation on the metal structure, the program is launched;
• type of electric motor power supply – from batteries or by connecting to the mains;
• function of rotating the drilling head relative to the workpiece. This makes it possible to form complex through and blind holes.

In addition to these design features, it is necessary to take into account the actual technical characteristics of the model. They determine not only the list of operations performed, but also their quality.

To reduce the size of the machine, a gear drive is often used instead of a traditional belt drive. Thanks to it, you can adjust the rotation speed of the drill.

List of technical parameters

After choosing a machine model based on its design features, you can begin to analyze its technical characteristics. First of all, you need to pay attention to the dimensions of the equipment. They will determine the possibility of installing metal structures in hard-to-reach places.

In addition to the main technical characteristics, the size of the magnetic sole is unique. This parameter determines the installation dimensions of the equipment installation site. The manufacturer also indicates the possibility of horizontal or vertical installation. This is necessary to know to form holes in structures with complex configurations.

The list of main technical characteristics for a drilling machine on a magnetic base largely coincides with the standard parameters of such equipment:

• electric motor Its power input and output, type;
• spindle head rotation speed without surface treatment of the workpiece. Ability to change this parameter while the machine is running;
• maximum and minimum drilling diameter;
• maximum permissible force on the drilling head. To avoid its breakage, a protective mechanism is provided in the design;
• the force of attraction of the magnetic sole;
• displacement of the drill chuck along the stand;
• maximum reach of the drill relative to the surface of the workpiece;

These characteristics are described in detail in the technical data sheet of the device. Additionally, the equipment and operating conditions should be taken into account. Almost all models of drilling machines with magnetic pads are designed to work in open space. However, this should be checked before purchasing.

One of the important properties of the device is the location of the control components. They are usually located on one of the sides of the machine. This must be taken into account when installing it on a metal structure.

Features of operation

After purchasing a magnetic levitation drilling machine, you should perform correct assembly and configuration. Then you need to check its functionality before installing it on the material being processed.

The necessary equipment parameters are pre-set: rotation speed of the working shaft, drilling depth, etc. Then the machine is installed on the metal surface of the metal structure.

Procedure for operating the machine.

1. Make sure the metal surface is smooth and free of debris or other components that would prevent the magnetic pad from making tight contact.
2. Install a drill of the required diameter on the equipment.
3. Mount the machine on a steel surface and check the reliability of fixation.
4. If work is performed on non-horizontal surfaces, it is necessary to use a safety rope. It will prevent the machine from falling if the magnet does not work.
5. For models with manual adjustment, drilling must be done according to previously developed technology. The depth of processing is taken into account, as well as the hardness of the material.

To move the machine along the surface of the structure, you must turn off the electric motor, wait until the drill stops completely, and only then deactivate the magnetic pad. Installation and subsequent operation are carried out according to the method described above.

On average, after 50 hours of operation, it is necessary to check the integrity of the mating of components and parts. This is due to the vibrations that occur during drilling. They negatively affect the structure.

Possibility of self-production

Machine with the ability to install a drill

Despite all the above positive qualities, drilling machines with a magnetic base are highly expensive. Therefore, many people think about the possibility of making them themselves.

the problem lies in matching the hardware components. The design of the machine must be small enough, but at the same time perform the functions assigned to it. Unlike classic models, torque is transmitted not using a belt drive, but a gear drive. Making it yourself is problematic.

The way out of this situation is to purchase a magnetic levitation stand with the ability to install a hand-held processing tool. Magnetic drilling machines of a similar design have the following performance qualities:

• The tool mounting block is designed for mounting a drill or router;
• small sizes;
• Possibility of mounting on a structure in a horizontal or vertical position.

However, along with these qualities, such a unit is characterized by worse performance indicators than full-fledged models. It is also necessary to take into account possible difficulties in operating the equipment.

To solve the last problem, you can make a remote control unit for a hand drill. This will allow you to control the process of forming blind or through holes remotely. Additionally, you can purchase or make a coolant supply system. It will be a small container installed on the drill body. Using a hose, liquid is supplied to the treatment area.

An example of how such an installation works can be found in the video:

Magnetic drilling machines: electric and pneumatic

Magnetic drilling machines are designed for drilling, milling and threading (if equipped with reverse) in metal workpieces in all planes. Their main advantage compared to classic drilling machines is mobility: they are relatively light in weight and can be easily transported from place to place.

They are capable of processing parts in hard-to-reach places, working in a horizontal position, being secured using an electromagnet to parts with a thickness of at least 9 mm (including on the ceiling). Portable magnetic drilling machine is used in construction, mechanical engineering, shipbuilding and other similar industries.

The machines are equipped with electric and pneumatic drives. Pneumatic ones are designed for processing parts in places where there is no electricity or explosive objects. Electric - powered by 220 V mains or batteries.

According to the spindle feeding method, they are classified into:

• with manual feed - feed occurs due to rotation of the steering wheel;
• automatic feeding – carried out by the feeding system when it is activated. Allows you to increase the drilling speed by 30% compared to machines with manual feed.

According to the layout method, magnetic drilling machines are divided into:

• vertical – classic vertical spindle arrangement;
• angular - the motor is installed horizontally and connected through an angular gearbox to a vertical spindle. This reduces the size and allows these drilling machines to be used in areas with low heights.

1. container for cutting fluid;
2. electric motor with gearbox;
3. spindle;
4. magnetic sole;
5. control Panel;
6. bed;
7. coolant supply tube.

Specifications

The main technical characteristics when choosing magnetic drilling machines are:

• power is a parameter that affects the productivity of the machine: the greater the power, the more work the equipment performs per unit of time;
• maximum drilling diameter - what is the largest hole that can be drilled in steel with a core drill;
• spindle rotation speed - the maximum rotation speed of the tool - some models have the ability to change the rotation speed by changing the gear ratio, as a result, when the rotation speed is reduced, the torque increases, which allows you to machine large holes without stress on the gearbox;
• spindle fit – the spindle can have a Weldon 19 fit or a Morse taper of the appropriate size;
• Magnet clamping force - the force with which the magnetic base is magnetized to the part. Depends on the model of the machine, its technical characteristics and purpose.

In addition to the characteristics described above, you should also remember about the secondary ones, which also influence the choice:

• volume of work - if you have a large volume of work, then it is better to choose a professional machine designed for intensive work conditions;
• type of material - since the machine is magnetic, then the material must have magnetic properties;
• cutting depth;
• the average weight varies between 10 – 25 kg.

Machine capabilities

Magnetic drilling machines allow you to make holes with a diameter of 1 to 150 mm and a depth of 200 mm in steel using twist drills and core drills.

When using twist drills, the maximum hole diameter that the machine can make is reduced and is (depending on manufacturers) about 42 mm.

To eliminate such unpleasant moments as jamming of the cutting tool and its breakage, some models of machine tools use a slipping clutch, which stops the engine when such situations occur.

The machines are capable of fastening well on ferromagnetic materials with a thickness of 9 mm. If the material is thinner, it is recommended to place a sheet of ferromagnetic material under the workpiece until a total thickness of 9 mm is formed.

To install magnetic drill presses on non-magnetic surfaces, use a vacuum mount.

When drilling pipes, a chain fastening is used.

Additional Drilling Accessories

When purchasing, pay attention to additional options that expand the functionality of the equipment:

• Coolants – increase the service life of cutting tools and reduce friction;
• containers of various volumes for coolant;
• turning magnets;
• vacuum fastening;
• drill chucks;
• core drills - allow you to obtain through holes of a larger diameter compared to spiral drills by cutting only part of the volume of material, the teeth are made of high-speed steel and carbide steels;
• taps.

Slow, insufficient feed rates will shorten the life of core drills and cutters and reduce machining productivity.

When choosing a drill material, you should be guided by the following considerations:

• if the hole diameter is less than 35 mm and it is necessary to process a material of low strength, then choose high-speed steel;
• if the hole diameter is more than 35 mm and high-strength materials are processed, then carbide cutters and drills are selected.

Spindles of various models are made with a Morse taper fit.

Drilling machine on magnetic base (magnet)

Such machines are used when it is not advisable or impossible to bring and install the workpiece or a separate part of any design on a stationary drilling machine.

The main work for which such a machine is indispensable is the so-called field work: the construction of tanks, pipelines, and various metal structures.

The plane on which the electromagnetic drilling machine on a magnetic sole is installed must be metal, magnetic and at least 9 mm thick.

The machines are equipped with a gearbox with a special slipping clutch. Such a coupling is necessary to protect the engine from increased load and damage. The clutch is activated when the drill or other cutting tool jams. Thanks to it, the electric motor is turned off.

Buy a drilling machine with a magnetic sole: tips

Once you have determined that you need to buy a magnetic drilling machine for your tasks, select the model you need. Below are the main parameters that you need to pay attention to.

Maximum drilling tool size

The maximum diameter of the cutting tool used on machines of this type is 130 mm. The maximum depth of holes is 200 mm.

Thread cutting

Not all models are capable of performing this operation. It is necessary to clarify the possibility of this operation on a specific machine model.

Motor power

Electric motor power affects equipment performance. The power of these machine models is usually in the range of 1000-1800 W.

Magnet adhesion force

The larger the hole that needs to be made, the greater the magnet adhesion force must be. When processing large diameters, it is worth choosing models with two magnetic coils.

Machine cost

The price of a magnetic drilling machine depends entirely on its characteristics. More expensive machines have high power, the ability to perform thread cutting operations, and high magnet adhesion force.

Accessories

It is worth paying attention to the shank option of the cutting tools that are used on the selected model. Some manufacturers produce machines with unique mounting of cutting tools, and drills and cutters with universal mounting cannot be used on them. The most common shank for magnetic levitation machines is the 19.05 Weldon grip shank.

Types of magnetic drilling machines

[Magnetic drilling machine] is very convenient when it is necessary to perform relevant work on large-sized equipment, the dismantling of which is impossible for various reasons.

These devices are portable and, due to their high mobility, can be easily moved from place to place.

A magnetic machine makes it possible to carry out the necessary work on almost any plane, including a horizontal one.

Its principle of operation completely coincides with the most ordinary unit of this type, in addition, the functional set is almost the same.

Its mounting on the working plane is carried out on a special base, which can be made either on a magnetic sole or on a cushion.

The magnetic drilling machine uses core drills and easily copes with the work for its intended purpose, in addition, it is suitable for processing a wide variety of types of surfaces.

 If necessary, a special cutter is fixed into its chuck, which further increases its functionality.

Equipment of this class, the price of which is within acceptable limits, can be purchased at almost any hardware store.

It is worth noting that the price of a magnetic drilling machine mainly depends on its capabilities and manufacturer.

:

• Some features
• Basic operating principle
• Classification and types

Some features

A drilling machine, the price of which is within reasonable limits, is currently actively used not only in a variety of industries, but also in everyday life.

It is suitable for processing almost all types of metals, regardless of their thickness, and uses core drills.

It is attached to a magnetic sole or cushion on a base whose thickness must be at least nine millimeters.

If the surface of the material being processed is below this indicator, you can attach the magnetic machine to the base through a steel sheet.

These devices are equipped with an operating mode in which it is possible to lower the chuck containing the core drill or cutter at the maximum optimal speed for this, and after completing the necessary work, it quickly returns to its original position.

IMPORTANT TO KNOW: Types of tabletop drilling machines

In addition, manual lowering of the working tool is also provided.

It is also worth noting that the magnetic machine has a relatively small weight, the value of which is within sixty kilograms.

This makes it possible to move it to the desired location if necessary.

It should be noted that there are special models of this type of units that are intended exclusively for work at home.

They are distinguished by their compactness and incredible mobility, despite the fact that their price is within acceptable limits.

In such home units, if necessary, core drills are also removed and a small cutter can be installed.

As practice shows, the price of such universal devices is somewhat lower than equipment of a similar type, which further increases the feasibility of their use for metal processing.

Almost every magnetic machine is additionally equipped with protection, which makes it impossible to put it into operation unless it is well secured to a magnetic base or pad.

In addition, protection is provided for all its main components.

For example, if during operation the load on the drill increases, both in its rotation and in the displacement of the axes, it automatically stops until the comments are eliminated.

It also has a special system that does not allow it to operate in automatic mode in the absence of power.

An affordable price, an additionally installed cutter and high maneuverability make this device indispensable when performing a wide range of tasks.

Basic operating principle

The price of such universal units fully corresponds to their high quality.

The drilling machine uses exclusively core drills in its work; in some individual cases, a special cutter can be used.

Core drills have some design features that allow them to work on thick metal surfaces.

As is known, when drilling on a thick surface, mechanical heating of the working tool occurs, which in some cases, if overheated, can lead to its breakage.

Devices of this type provide automatic supply of a special cooling and at the same time lubricating fluid into core drills from the inside.

Accordingly, at the moment the processing is completed, the liquid automatically stops flowing into the drill.

IMPORTANT TO KNOW: Types of drilling and filler machines

Thanks to this device, core drills have a long service life.

Due to the design features of the chuck, core drills or cutters can, if necessary, be replaced with new ones within a few minutes, which significantly increases the productivity of the device as a whole.

One of the main advantages of drilling machines of this universal type on a magnetic pad or sole is that they can be used to process those surfaces that cannot be placed on the base of an ordinary stationary unit.

Due to its design features, a magnetic machine is capable of turning the surface of the metal itself, which is to be processed, into a workbench.

In addition to its direct purpose - drilling holes, this unit is also capable of performing countersinking and thread cutting.

In addition, if a milling cutter is used, the device can easily perform primitive milling operations on a metal surface.

It is worth noting that for equipment of this class, a drilling machine of this universal type on a magnetic levitation (base) has an expanded functional set.

It is suitable for processing a wide variety of metal surfaces. The performer of the work does not require any professional qualifications.

The device is controlled using several buttons and levers located on its front part.

Classification and types

Drilling machines of this class may differ from each other in some operating parameters.

So, these units may have different diameters of the annular cutter or spiral drill.

Also, devices can have different countersink diameters or different stroke lengths.

Drilling machines of this class can have different power, which mainly depends on the engine installed on them.

The engine also affects the rotation speed of the moving parts of this type of equipment.

It should also be noted that the magnetic pads designed for attaching them directly to the surface of the metal being processed may also differ between machines.

When choosing a machine of this type, price should not be the main determining factor.

All of its main operating parameters, which indicate its functionality, should be taken into account.

If it is assumed that the main working tool will be a milling cutter, then it is best to pay attention to those drilling machines that have higher power ratings.

IMPORTANT TO KNOW: Types of vertical drilling machines

In addition, it is necessary to pay attention to the rotation speed and the presence of safety systems.

The price of machines of this class largely depends on the name of the manufacturer, but the declared quality does not always correspond to the actual operating parameters.

Such devices are designed to perform a wide range of work operations, and therefore must contain a maximum range of different functions.

A cutter must be provided as one of the working elements, which must be easily and quickly installed in the chuck.

In addition, such devices must be protected from various external influences.

You should also pay attention to the possibility of installing them on a horizontal surface.

In general, in such drilling machines of this universal type, a lot depends on the quality of the magnetic fastening.

It must not only firmly fix the unit in place, but also withstand possible additional loads, including when the cutter is working.

The main working body of such devices are core drills, which during their operation are cooled in the form of a special oil liquid.

When choosing a unit of this type, you should also pay attention to the installed cooling system.

A magnetic machine designed for drilling metal surfaces is highly mobile and efficient equipment that allows you to solve relevant problems of any complexity.

When using a magnetic drilling machine, it does not matter in which plane the surface being processed is located.

Due to its magnetic fastening, it can be easily mounted both vertically and horizontally.

The price of such equipment is within acceptable limits, which makes it possible for even a home craftsman to purchase it if necessary.

It should also be noted that a drilling unit on a magnetic base or sole, using core drills, is easy to operate and control.

How to choose a magnetic drilling machine

First of all, let's find out how a drilling machine with a magnetic base differs from a regular stationary drilling machine, and then we will answer the question of how to choose a machine with a magnetic base.

Using a drilling machine, you can perform the following types of work in ferrous and non-ferrous metals, as well as other materials:

• drilling;
• reaming;
• thread cutting;
• countersinking;
• countersinking.

The magnetic drilling machine is designed for work where conventional stationary machines cannot be used. Their main advantage is that it is mounted in the right place on a metal plate or sheet due to the clamping force created by an electromagnet.

Due to the built-in electromagnet, the drilling machine has acquired an irreplaceable quality such as mobility and the ability to perform work in unprepared conditions during the construction of steel structures, bridge structures, construction tanks, pipelines and in shipbuilding.

Work on drilling machines with a magnet can be performed both in a horizontal, vertical position, and also when working overhead.

Stationary or magnetic drilling machine

If you carry out work far from the main production (For example: building bridges) and it is not possible to drill a hole or tap a thread on a stationary drilling machine, then your choice is a drilling machine with a magnetic base.

Sometimes there are cases when, even when carrying out work next to a workshop with a stationary drilling machine, it is more expedient to perform the work using a drilling machine on a magnet due to the high labor intensity of moving the product to the workshop, as it requires the use of lifting mechanisms and other equipment, which leads to additional time and finance.

Drilling hole diameter

The main difference between the machines from each other is the maximum diameter of holes.

As the main tool used on drilling machines with a magnetic sole, core cutters are used, which are hollow inside, and cutting is carried out only by their peripheral part, which significantly speeds up the drilling process. However, the use of core cutters makes it possible to use only through drilling; if it is necessary to drill a blind hole, then in this case you will have to use a regular drill.

Thread cutting

This function is not available on all models, so if you need thread cutting, please check the availability of this function and the thread cutting range.

Motor power

When working with core drills, due to the smaller drilling area, it is possible to drill fairly large holes up to 100 mm, with a motor power of less than 2 kW. If you will carry out the main work with a large-diameter twist drill, then the motor power should not be less than 1.5 kW.

Magnet and adhesion force

Pay attention to the sticking force of the electromagnet, the larger the maximum drilling diameter of the hole, the greater the magnet sticking force required. We recommend that you pay attention to the electromagnet with two magnetic coils and also to the presence of pleasant functions that can extend the life of your machine, such as: adhesive force indication, overheating protection, etc.

Accessories. Milling cutters

Some magnetic drill press manufacturers make inclusive shanks, making it impossible to use cutters from other manufacturers, leaving you dependent on one manufacturer. The most common and convenient is the Weldon 19.05 grip shank.

Drilling machines with a magnetic sole (base or pad)

A drilling machine with a magnetic base, the price of which starts from 33 thousand rubles and can reach more than 125 thousand, allows you to process structures with complex configurations. It is not always possible to get by with a stationary machine or drill, so a device with a magnetic sole becomes an excellent solution to the problem.

Photo of a drilling machine on a magnetic base (cushion)

A drilling machine with a magnetic sole differs from traditional drilling units in its layout. There are no platforms that support the operation of stationary devices. Instead, magnetic plates are used.

The magnetic base serves to fix the device on the surface of the metal workpiece being processed. Moreover, the machine with a cushion can be located at an angle, horizontally or vertically. It all depends on what configuration of product you are dealing with.

The price of such devices is from 35-40 thousand rubles and above. There are models for 100-150 thousand rubles.

Structurally, drilling machines on a magnetic base look like this.

1. Magnetic base. The magnetic base is a mounting unit that secures the machine to a metal workpiece. We are talking about an electromagnet that is turned on and off by pressing the corresponding buttons.
2. Columns. These are supports for mounting the remaining elements of the machine.
3. Drilling block. The drilling unit includes a spindle with a locking chuck and an electric motor. The cartridge can move in height or be equipped with rotating mechanisms. This depends on the specific model of the unit.
4. The cooling system acts as an additional design element. It supplies coolant. The presence of this function is useful, since the quality of material processing improves.
5. Battery. Not available for all models. Most often, a drilling machine on a magnetic plate operates from the mains via a cord. Although in some cases it is important to purchase a device with a battery. The portable model has its advantages. But its power will be lower, which is important to consider when planning certain works.

Application nuances

Technical Specifications of Popular Magnetic Cushion Drilling Machines

Devices with magnetic levitation are used in a wide range of works. They are mobile and can be installed on various workpieces. The most important thing is that they are metal, otherwise the magnet simply will not be able to attach to the surface.

If the surface being processed does not have ferromagnetic properties, you should not put the machine on the cushion aside and look for alternatives. To correct the situation, an auxiliary steel plate is mounted on the workpiece. If the surface is not flat, round or does not correspond to the dimensions of the platform, mechanical fixation methods are used.

Taking into account the design and operational features of a machine with a magnet pad, the device can be used for the following operations:

• Making holes by drilling;
• Countersinking;
• Reaming;
• Creating threads;
• Milling.

A magnetic-based machine can only perform milling if the device is designed for this kind of load.

Classification

As such, there is no clear classification of drilling machines with a magnetic sole. But based on the technical and operational characteristics, it will be much easier for you to choose a model that suits your requirements.

1. Drill feeding method. It can be automatic or manual. Automatic is relevant when it is impossible to drill the workpiece manually. Before this, you need to configure the operating parameters of the equipment, then install the machine on the workpiece and activate the program.
2. Electric motor power supply. Machines with magnetic soles are connected directly to the mains or use rechargeable batteries. Battery devices are more mobile, do not require connection to a power source, but are inferior in terms of power.
3. Rotate the spindle head relative to the workpiece. If this function is present on a machine with a magnetic base, you will be able to make blind and through holes of high complexity.
4. Broadcast. Previously, only belt drives were used for such machines. But manufacturers have aimed at reducing the size of the device, as a result of which many modern versions of units with a magnetic sole are equipped with a gear drive. An important advantage is that it provides the ability to regulate the speed of rotation of the cutting tools.

Working with the machine

• Make sure that there is no debris or unevenness on the surface being treated that could interfere with the strong fixation of the magnetic pad;
• Insert a drill of the required size into the unit;
• Place the device on the surface and check how firmly the magnetic sole is attached to it;
• If you are working on a vertical or inclined surface, additionally secure the unit with a safety rope. This way you will protect the tool from accidental falling if the magnetic sole suddenly does not work;
• Start drilling;
• After completing the work, turn off the electric motor, wait until the drill stops, and only then press the button to deactivate the magnetic soleplate.

Devices equipped with a magnetic levitation have important advantages over stationary machines and hand drills.

Therefore, their relevance in the field of construction and repair is steadily growing.

Magnetic drilling machines - types, technical characteristics

On a construction site or in an assembly area with intensive assembly of metal structures, you can often find drilling machines with a magnetic base. They are intended for mobile use in industry and the construction industry for the purpose of drilling previously unforeseen holes in metal workpieces and structures.

It is difficult to do without these machines on a magnetic stand when installing large-sized metal truss structures, when performing work in inconvenient and hard-to-reach positions. This equipment is especially important in extreme situations that inevitably arise during intense and responsible work.

The main difference between a magnetic drilling machine is the presence in the design of a very strong magnet, which allows you to install it into the working position without any preparation and quickly start working.

In some of these machines the work table is equipped with an electromagnet, while in others permanent magnets are used. Sometimes these devices are called machines with magnetic soles.

Their device allows you to quickly secure yourself in a given position (horizontal, vertical and at an arbitrary angle) and perform the required operation.

This equipment is rightfully considered unique, as it is designed in an unusual way and is very convenient to use. Drilling machines with magnetic soles are used more and more often and are becoming increasingly popular among builders and installers, as they have wide functionality in the most unusual situations.

Application area of ​​the machines

If there is an unusual situation on a construction site where large diameter drilling needs to be done in difficult conditions, conventional drilling machines are useless. After all, due to the peculiarities of their design, they can drill only those parts that are located and fixed on their desktop. The solution in these situations is to use a magnetic drilling machine.

If we consider even large-format stationary drilling machines, their maximum lifting height of the working tool above the table is limited by the value specified by the manufacturer. These are strict restrictions, the designated limits of which cannot be exceeded.

The stationary machine also has important limitations. For example, if the part is large, then it is hardly possible to drill along its edge in one installation on the workbench. After all, the distance from the center of the stand to the axis of the drill is usually insufficient.

A drilling machine with a magnetic sole does not have this drawback.

It is compact, it can be transported and installed in new places without any difficulties, and the fixation due to the magnetic pad is so reliable that you can install the device and drill holes in any position anywhere in the steel structure.

Operations that can be performed efficiently and quickly with a magnetic levitation drilling machine:

• performing drillings of a given diameter at any point in the structure;
• cutting internal threads in holes;
• milling operations;
• reaming holes to the required diameter and specified finish;
• countersinking finished holes.

The power of the magnets holding the device in a given position is sufficient to create a pressing force of 25 kN. This makes it possible to securely fix the device on both vertical, horizontal and inclined surfaces. For cases where the surface of the workpiece is not sufficiently smooth, the machine is usually equipped with vacuum suction cups and chain clamps.

Magnetic levitation drilling machines are especially in demand at enterprises where it is necessary to drill holes in structures that are heavy and large in size.

Such parts cannot be placed on the desktop of a stationary machine; these are structures of bridges, high-rise buildings, parts of dams and other large-format building elements.

Portable drilling machines are used both in shipbuilding and wherever conventional equipment cannot be used.

Considering various models of magnetic levitation machines, you can see that their functionality and technical characteristics are very different. On some models, along with drills, it is possible to use other cutting tools - cutters, reamers, twist drills, etc. To produce large-diameter holes in thick parts, core drills and special reinforced cutters for a magnetic drilling machine are used.

Types of magnetic levitation drilling machines

Drilling machines with a magnetic stand have various drive mechanisms for the cutting tool. These are electric, pneumatic and hydraulic drives.

Electrically driven machines are more common, but they can only be used where there is access to connect the machine to the power supply line. It is important that the place of work does not contain explosive gas or an environment that is too aggressive in composition. The electric motor installed on the machine directly determines its functionality with its power. The most common are magnetic drills with an electric motor power of 1.4 kW and a total weight of 16 kg.

In pneumatic machines, the rotation drive of the cutting tool receives energy from compressed air. It is rational to use these machines in cases where it is not possible to connect a similar device to the electrical network.

Sometimes connecting to a source of electricity is simply unacceptable due to the safety conditions of the work. These include flammable and explosive media.

If you still use an electric drive under these conditions, then the design of the device must be made of alloys of a special composition that does not allow the formation of sparks in the working area.

Hydraulic driven machines basically contain a hydraulic motor driven by oil pressure. Such devices are designed to operate under water and in corrosive environments.

Selected models of machines with a magnetic stand

When a person is faced with a choice of which magnetic drilling machine to buy, he should consider specific models of these devices, comparing their performance parameters, functionality and price. Let's look at the most common models of drilling machines on a magnetic base.

BDS machines       

BDS magnetic drilling machines made in Germany are very popular among users.

These devices are used during the manufacture and installation of complex metal structures; they are designed to perform drilling of various diameters, cutting internal and sometimes even external threads. They are used in cases where it is not possible to use conventional metalworking equipment.

The MABasic 400 hovercraft drilling machine currently costs approximately 37 thousand rubles in Russia. The line of these devices contains models with different power characteristics, different weights and different sizes. The price of each magnetic drilling machine of the MABasic model also depends on these parameters, which can be significantly higher than that indicated for the 400 model.

MS machines

MS magnetic drilling machines are assembled in Belarus only from German components. They are designed to operate at high intensity over a long service life. The devices are equipped with electric motors from the Eibenstock company, which have an increased power reserve and a two-speed operating mode. Before installing the engine on the housing, its operational tests are carried out in the factory conditions of NPO Vector.

When using a core drill on an MS, the maximum diameter of the holes is 40 mm, but if drilling is done with a conventional drill, then 23 mm.

By purchasing an MS-4 machine, the client can be sure that he can immediately carry out the planned work without any problems. The convenience of this device is complemented by the fact that the body of the MS-4 magnetic drill is made of special light alloys with low density.

For storage and transportation of the magnetic drill there is a special plastic box with a comfortable handle. Belarusian Vector devices are safe to use and provide high quality work. Their long working life is determined by the wide temperature range of engine operation.

The price of Vector MS -4 is now 45 thousand rubles.

Buying a used machine

In addition to the presented two models of electric drills on a magnetic platform, you should also consider such models from world manufacturers as MAB, Euroboor and Magtron. This high-tech equipment has long proven itself to be the best in those areas of activity where it is impossible to use classic versions of drilling machines.

You should not neglect offers for the sale of used machines on a magnetic stand. The only verification test for the operation of this device will be testing the engine at elevated operating modes while securely holding the device on a ferromagnetic base. If the test is successful, there should be no doubt about the functionality of the device. By purchasing such a machine, you have the opportunity to save significant money.

Magnetic drilling machines: scope of use, types of drives, mounting on a metal surface

A drilling machine with a magnetic base is becoming increasingly popular among specialists. Thanks to its exceptional functional characteristics, the range of possibilities for its application is simply enormous. At the moment, the number of models on sale, varying in design and capabilities, can satisfy any professional. The main thing is the correct selection of the task that a specific machine will have to solve.

Although conventional drilling units are versatile, their capabilities are still limited. For example , the workpiece must be fixed strictly on the work table and have a suitable height. After all, even the largest machines have limited vertical lift of the drill. The distance of the drilled holes from the edge of the workpiece is also limited, because the support post is located close to the axis of the drill.

A drilling machine on a magnetic base does not have such limitations; it is compact and capable of performing a variety of operations. Thanks to its magnetic pad, it can be attached to any metal surface that needs processing. This machine can perform the following operations:

• drill holes of a given size;
• cut threads inside the part;
• milling;
• deployment;
• countersinking.

with which it can be used depends on the model of the device Twist drills and core cutters are used to make holes smaller than 32 mm in diameter on thin workpieces. To drill holes with a diameter of up to 150 mm, core drills and reinforced cutters are used.

The stand is based on a magnet with a power of up to approximately 26,000 N, thanks to which it is possible to fix it in a horizontal, inclined or vertical plane on a metal surface. If the surface lacks stability or is unsatisfactorily even for reliable fastening, it is possible to use vacuum or chain clamps.

Magnetic machines are widely used in industries that require drilling on large objects. These include: work in shipyards, bridge construction, construction of high-rise and other metal structures. Compactness and low weight allow the machine to be used in places where it is not possible to use an ordinary analogue.

Types and design differences

Devices are divided into types depending on the drive used:

• electrical;
• pneumatic;
• hydraulic.

Electrically driven units are the most widely used on the market. They are used in places where it is possible to provide electrical power and there is no danger of explosion. The electric motor provides the torque of the drill; the functionality of the machine directly depends on the engine power. The most popular ones in production are small-sized units, weighing up to 16 kg and electric drive power from 0.75 to 1.4 kW.

A pneumatic magnetic drilling machine is a unit in which drilling occurs due to the pressure of compressed air. It is used in explosive areas and where it is impossible to install an electrical network.

Individual parts of the equipment design are made of non-sparking metal alloys, which additionally ensures safety when working with the machine.

The hydraulic type of installation is a hydraulic motor powered by oil pressure. These devices, made of anti-corrosion materials, are used in underwater work or at high humidity levels.

Since a magnetic drilling machine is mainly used when working with thick, large parts, when drilling the latter, the tool is subject to strong heating. To prevent drill breakage, cooling means are used. Basically, water poured into a special tank is used for this. Fluid is automatically supplied to the drilling zone, so the machine is equipped with a tube and a pump.

To protect the worker and the mechanism in emergency situations, a safety mechanism is installed in modern units. A large number of manufacturers install a slipping clutch in the gearbox for such purposes. When the tool gets stuck in the workpiece, the drive and clutch with the fixed drill or cutter are disconnected.

The main characteristic of a machine with a magnetic levitation is its weight. Therefore, the installations are equipped with commutator electric motors.

The engine power varies from 0.6 to 3 kW, the number of shaft revolutions is no more than 1100 rpm. At higher speeds it is impossible to ensure high-quality cooling of the working tool. Only Japanese manufacturers use carbide tools in their machines and can afford to exceed the speed limits mentioned above.

Inexpensive machines with 250-600 rpm can effectively cope with drilling holes with a diameter of 18 to 38 mm.

Securing the drilling rig to the surface

Strong fixation of the unit with a magnetic cushion and surface is possible subject to strict compliance with a number of requirements. The most important of them is the mass of the part with an allowable thickness of more than 6 mm. When the machine operates, vibration occurs, which, if sufficiently intense, can move the device from the surface of an oversized workpiece.

The area of ​​the workpiece plays an important role. For reliable fixation, the surface to which the machine will be attached must be no less than the area of ​​the magnet. The magnet also has less strong adhesion to painted surfaces.

If the reliability of fastening the installation to the part is not trustworthy, additionally use fixing belts. When working with pipelines, you also need to use additional means of fixation - chain platform . A machine on a magnetic levitation is attached to its upper, flat part, and the structure itself is attached using a pair of chains.

There is now a large range of drilling machines that can be mounted on non-metallic surfaces. The coupling is provided by a vacuum, which is created by a special pump. Such installations can only work on perfectly flat surfaces.

The most famous brands of manufacturers of magnetic drilling rigs: BDS, ALFRA, Eibenstock, RUKO, Magrtron, Nitto Kohki. The products of these companies are distinguished by the quality of their products and high performance indicators. This makes them more expensive compared to their Chinese and Russian counterparts.
