Sharpening a chainsaw chain with your own hands: subtleties, effective methods

The quality of a construction tool is not just a matter of efficiency, but also of work safety. That is why you should carefully monitor the condition of the working parts of any tool, including chainsaws. It is necessary to sharpen the chain in a timely manner and it is not necessary to contact a specialist: you can carry out the entire process yourself. Below is a detailed description of the technology for sharpening a chainsaw chain with your own hands (video instructions are attached).

Sharpening a chain on a chainsaw: the need for the procedure and the subtleties of its implementation

In order not to waste your time in vain, you need to know for sure that the chain on the chainsaw is already dull. This is quite easy to determine. So, a well-sharpened saw gently and quickly enters the tree. If you feel even the slightest resistance while working with wood, this is the first sign that the chain is already dull and should not be delayed in sharpening it. The fact is that chain wear can affect very important indicators in the following ways:

• tool productivity decreases;
• the load on the body muscles increases;
• fuel consumption increases greatly;
• The chain links are overloaded, thereby reducing the service life of the tool.

Chainsaw

In order to properly sharpen a chainsaw chain, you need to have special skill, and it can only appear if you have an understanding of the structural features of the saw. The fact is that the teeth of the chain have a rather complex and unusual structure, and accordingly, the sharpening process turns into a rather painstaking task.

So, the edge of the chain is densely covered with teeth, which have 2 edges: top and side. One chain link is represented by a base, a blade and a depth stop.

How quickly the saw chain becomes dull depends directly on the load on the tool and the conditions in which the work is carried out. So, all you need to do is hit the stone or ground with the saw a couple of times and you will have to sharpen the chain.

The best ways to sharpen a chainsaw chain

There are several ways to sharpen chainsaws, each of which has its own advantages and features. Further details about each of them.

Sharpening with a file

Sharpening with a file is one of the most common, simple and effective ways to sharpen a saw. Most often, specialized stores sell ready-made kits (sometimes together with a saw) for sharpening electric and chainsaws. The simplest set consists of the following elements:

• a cylindrical file installed in a holder;
• flat file;
• hook and template to determine the desired stopper depth.

Sharpening with a file

Use a file to sharpen the teeth of the chain carefully, smoothly, without putting excessive pressure on the tool. It is advisable to secure the tire before starting work. After this you can start working. So, we install the holder on the tooth being sharpened, hold it in one position and lightly press the file against the edge being sharpened. After this, we make several smooth movements from ourselves.

We repeat the process in a similar way with all the remaining teeth. It should be remembered that all teeth must be sharpened equally. This can be achieved by using the same force to sharpen each tooth and performing an equal number of movements.

Advice. During the process of sharpening chain teeth, it is necessary to periodically turn the file in a circle. This will avoid severe wear of the sharpening tool on one side.

Sharpening with a grinder

This method is considered one of the simplest and most accessible, but with one caveat: if you have a grinder at hand and know how to use it. Otherwise, the sharpening process may not be so simple.

Sharpening can be done using a grinder

The peculiarity of this sharpening method is that the chain does not need to be removed from the saw while sharpening its teeth. For sharpening, you should prepare a previously used metal disc with a thickness of about 2.5 mm.

The grinder should be set to minimum speed, and the process itself must be carried out, gradually moving in order from one tooth to another.

Sharpening on a machine

Unfortunately, in some cases, manual sharpening of teeth is not enough. This occurs when the saw has been used so often and without regard for the consequences of careless use that the edge of the blade turns into something shapeless. It is for such cases that a machine can be considered the best option.

To sharpen chain teeth, one of the following types of machines is most often used:

• Manual machine. This is more of a special device than a machine. The working part of a manual machine is similar to a bow saw, however, a cylindrical file is used here. The mechanism of such a machine is quite complicated, but with careful adjustment it is capable of completing the sharpening process in the most precise manner.

Saw sharpening machine

• Electric machine. Sharpening is carried out directly by an abrasive disc built into the machine. Automatic tuning allows you to set the optimal parameters quickly and in the best way. In addition to the machine, in some cases there is a protective mask that will prevent sparks and chips from getting into your eyes.

That's all you need to know in order to quickly and competently sharpen your chain. Good luck!

Do-it-yourself chainsaw sharpening

 Having bought a chainsaw once, you should not think that it will always work as efficiently as on its first day. The initial apparent ease of wood processing may disappear over time. An inexperienced saw owner may not immediately understand or notice that the saw is dull.

As a result, this may no longer lead to sharpening the chainsaw chain as a preventive measure, but to restoring it in special service centers, using chain sharpening machines, or worse, to completely replacing it with a new one. In this article we wanted to talk specifically about timely maintenance and chain sharpening.

When, how and with what help it is necessary to carry out such procedures so that you can saw without problems, and your saw can work efficiently and for a long time.

How to extend the period from sharpening to sharpening a chainsaw

 Maybe now we will utter common truths, but some people neglect them, apparently in the hope that everything will work out without it, according to the phrase of the hero of the famous cartoon “Vovka in the Thirtieth Kingdom” - “Oh, that’ll do.”

 Under no circumstances should you cut with a saw if there are foreign objects in the wood or board, first of all, nails that have not been removed, or a metal strip. Once you “drive” over a normal nail, you will, of course, even saw it through, but after that, take a look at the cutting edges of the chainsaw chain, because sometimes this is an irreparable defect, with chips and plastic deformation of the teeth.

In such cases, a hand chain sharpening tool may not always help. Before starting work, check the saw area for the absence of any foreign objects; the wood must be clean, preferably dry, although this will depend on how it turns out. You should not cut on the ground without placing something under the cut.

In this case, after cutting you will have to go deeper into the ground, and this is oh, how undesirable for your chain. Earth, sand, stones, all this can also quickly and irrevocably damage the chain of your chainsaw, forcing you to start sharpening it after one or two uses of the new chain.

 Make sure that the saw does not “bite” while cutting, so as not to overheat the metal and the blade of the saw. Monitor the chain lubrication and the oil level in the tank. As a result, as you understand, the chainsaw, which seems to be such an “invincible” hand tool, itself needs protection if you want accurate, timely and efficient work from it.  

Signs that a chainsaw (power saw) chain needs to be sharpened

Having briefly outlined our thoughts in the previous paragraph about what not to do so as not to start sharpening immediately after 5 minutes of working with the saw, in this paragraph we will talk about the signs of a dull chain, that is, when the time for sharpening has already come, it doesn’t matter how long have you worked? Pay attention to the saw shavings. So, with a blunt chain, it will be smaller, in some cases not light, but slightly darker than usual.  

 Everything is explained very simply, dull edges cannot remove the proper cutting layer, which leads to shredding, and high speeds without proper heat removal, along with the chips, overheat the wood, causing it to burn and darken.

 
 And of course, the main signs indicating the need for sharpening is a direct visual inspection of the chain.

  There should be no radii on the cutting edges, there should be no damage in the form of tears or changes in the shape of the tooth and cutting edge of the chain.

Otherwise, the chain must be sharpened

Negative consequences in case of untimely sharpening of a chainsaw chain

 If you continue to saw, despite the fact that the chain is dull, then this will primarily affect your productivity and possibly your nervous system, which does not accept such ordeal. This will also affect the service life of the electric or chainsaw, due to the fact that the engine will overheat.

  Increased consumption of gasoline and electricity. It will also be reflected in the shank, which the saw will go through much more times in order to cut the same thickness, compared to a sharpened chain.

  The chain may get into such a state that it will have to be adjusted by a machine in a specialized center, or worse, replaced, we have already talked about all this

The process of sharpening a chainsaw chain with your own hands

 Sharpening a chain means having a special tool, even for manual sharpening. In fact, this is a set that can be purchased in stores. It consists of a set of two files (round, flat), a mandrel and a gauge. Sometimes it is supplemented with a hook for removing chips from the slots of the chain. One of the files, round, is combined with the mandrel. The flat file and gauge are used on their own, separately.  

The chain is sharpened directly on the saw blade. The mandrel is placed on the edge of the cutting tooth, taking into account the chamfer sharpening angle. The sharpening angle is usually 30 degrees or 10.

The most difficult thing about manual editing and sharpening is maintaining this very angle. Here you need to have some practice and feel the direction of sharpening in order to precisely correct the direction of movement of the round file, and not sharpen your own angle.  

Also, when sharpening, you should pay attention that the movement of the file should be in a perpendicular plane relative to the saw blade. The main difficulty of manual sharpening is that all angles must be maintained manually, which will require proper dexterity and experience from you.

The file itself should protrude slightly above the tooth when sharpening it.
Sharpening is carried out in one direction, that is, only in a translational motion, and not in a reciprocating motion. Next, after sharpening the first tooth, we turn the chain on the shank and similarly proceed to sharpening the second, then the next one, etc.

After you have “walked” along all the cutting edges of the teeth, it’s the turn of the cut stops. In fact, these are protrusions on chains that do not have cutting edges. The limiters are located on the same plate with the tooth. Their main task is to limit the cutting depth.

If they protrude too much, the chain will slide rather than cut. If they are too deep, the saw will “bite” in the wood.

To adjust the cut stops, you need to take a gauge and apply it also to the edges of the cutting teeth. The end plate with the slot should be exactly at the level of the limiter. If the limiter protrudes from the caliber, then it should be trimmed to size. The stops are leveled with a regular flat file, and also work with the file in a plane perpendicular to the saw blade and in one direction.

Sharpening a chainsaw chain in specialized centers, on a machine (features and cost)

If your chain is in a very poor condition or you feel that you are not able to sharpen it yourself, then contact a specialized center, or purchase a chain sharpening machine that minimizes the influence of the human factor when sharpening the chain.

 In this case, the chain is removed from the bar and installed on the machine guide. Next, it is tensioned by a roller and a ratchet holding it by the cutting tooth. The sharpening angle is set according to the protractor on the machine. Next, the abrasive wheel is lowered and literally a few tenths of a mm are removed, that is, the chain is straightened and sharpened.

  Next, the chain is moved to the next tooth, etc.

  Such sharpening makes it possible to meet higher requirements for the size of the cutting part of the chain and its shape. The disadvantage is also obvious that here you will have to buy an expensive machine, which is not always advisable for one-time sharpening of a chainsaw chain.

 The cost of such a procedure in service centers will be about 3-5 dollars, but the machine itself can cost several thousand rubles.

 An alternative option for a private owner would be to use a manual machine; it is somewhat cheaper than an electric one, but the processing speed will be somewhat lower, although the accuracy is comparable to the machines used in the service.  

Now knowing about all the alternatives when sharpening a chain, you yourself can choose what seems to be the most suitable option.

Do-it-yourself electric saw chain sharpening - Metals, equipment, instructions

Everyone knows that the saw chain used in chainsaws requires periodic sharpening, but not everyone knows how to do it correctly. It is very easy to determine that a saw requires chain sharpening; to do this, you need to inspect the sawdust, and if it consists of fine dust, then the tool needs to be sharpened. If it is impossible to sharpen, you should replace it with a new one.

Using an unsharpened chain can lead to engine overheating and scoring on the cylinder.

Let's look at the main ways you can sharpen a chain on a chainsaw without any problems.

How to sharpen a chain on a chainsaw with your own hands

A person who has a chainsaw on his farm should know how to sharpen a chainsaw chain with his own hands. There are several ways:

• Sharpen using a file (the most common method of sharpening, since it allows you to sharpen the tool directly at the site of sawing work.)
• Sharpen using a special machine (this method is used in service centers, but can also be used in private households)
• Sharpen using a grinder. Sharpening using this method requires certain skills. A less common method, because It is quite difficult to sharpen correctly using an angle grinder.

In this video, you can familiarize yourself with the sharpening process, the most popular methods and tools used for this.

Sharpening with a file

The first thing you need to sharpen a chain or correct it a little is special files.

File

For sharpening and straightening saw chains, two types of files are used. The first is a round file with a diameter corresponding to the rounding diameter of the working edge of the saw tooth.

For sharpening saw chains of household tools, round files with a diameter of 4, 4.8 mm are used, this is due to the fact that they have a small tooth. For professional models, more powerful chains with larger teeth are used, and accordingly, files with a diameter of 5.2, 5.5 mm are needed.

In order to sharpen correctly, it is not enough to sharpen only the cutting edges of the tooth; you also need to adjust the cutting depth limiter.

If this is not done, the chain will not cut into the material being cut to the required depth, which will significantly reduce the speed of work and, just like in a situation with a blunt chain, can lead to overheating of the saw engine due to insufficient load on the engine. This work is done using a flat file.

Description of the sharpening process using files

The first step in straightening a saw chain on a saw is to place the tool on a flat platform or table. In forest conditions, a large diameter chock is well suited for this.

Next, you need to inspect the saw chain for any defects, these could be cracks or completely broken teeth.

After inspection, you need to set the brake to working condition, thereby blocking its movement on the tire.

The chain must be tensioned when sharpening with a file.

It is advisable to place a stand under the bar; you can use a log, a piece of a branch of a suitable diameter as it, or manufacturers of sharpening tools have special clamps to hold the bar while sharpening the chain.

The chain is sharpened by moving the file from the inside of the tooth outwards. In this case, the file should be located parallel to the special mark on the chain. This mark is applied by the chain manufacturer to indicate the standard sharpening angle.

The tooth being sharpened should be located approximately in the middle of the bar, this is necessary for the convenience of work; during the sharpening process, you need to move the chain along the bar, not forgetting to set the brake to the working position each time.

The work of sharpening a chain on a chainsaw must be carried out using gloves made of rough material, otherwise it is quite easy to injure yourself, because the working surface of the teeth is very sharp.

Ideally, manufacturers advise performing the same number of file movements for each tooth, but in practice this is not always possible, because the teeth have varying degrees of damage to the working edge.

To facilitate sharpening the saw chain using a file, special holders with corner markings applied to them can be used. Markings are made not only for a standard transverse cut, but also for a longitudinal one.

Tool holders are also convenient to use if you do not have sufficient sharpening experience. Experienced craftsmen do not use holders for sharpening, but can only use special devices that support the file.

Another device designed for sharpening is a manual saw chain straightening machine. It uses a regular file as a sharpening tool, which you can replace yourself. The machine is mounted directly on the tire; it also has the ability to adjust the angle of sharpening the tooth and a special stop that holds the tooth being sharpened.

Manual sharpening machine, perfect for beginners. Along with electric models of sharpening machines, manual ones have their undeniable advantage in the form of a low price. Depending on the manufacturer of the manual machine, their appearance may vary, but the principle of operation is the same for all.

Adjustment of the cutting depth is done using a flat file, so that there is a difference between the upper cutting edge of the tooth and the height limiter.

As a rule, the gap size is adjusted using a special die. It is installed on the chain during sharpening, after which the depth stop is ground off.

Electric sharpening machines

To straighten a large number of chains, as a rule, in service centers or at manufacturing plants, electric sharpening machines are used. Depending on the manufacturer, the design of the machines may vary, but they have the same operating principle.

The saw chain is installed in a special guide, which is mounted on the basis of a rotating platform and has a special clamp to hold the tooth being sharpened. The latch is capable of moving in a horizontal plane.

An electric sander is installed at an adjustable angle to the tooth being sharpened, which is turned on by the operator by pressing the start button. The depth of immersion of the emery, as well as the angle at which sharpening is done, can be adjusted. The dive itself is performed by the operator.

  The chain is straightened with a special grinding wheel, which can be changed if necessary.

How to sharpen using an angle grinder (grinder)

The method of sharpening a saw chain using an angle grinder is the least common because it is not safe. In order to straighten the teeth of a chain using a grinder as a sharpening tool, you need to install it in a vice and clamp it securely.

Next, the tool is turned on and the tooth edge to be sharpened is placed on the rotating surface of the disk. A tooth sharpened in this way can differ significantly from one sharpened with a file, because

During the editing process using a grinder, it is quite difficult to control the sharpening angle.

A big disadvantage can be considered the possibility of cutting the eyelet of the connecting link of the chain with the grinder disc, which will subsequently lead to rupture during work.

If in the process of working with a chainsaw the need for sharpening arises, it is better to use a special tool rather than come up with various tricks that can result not only in financial losses, but also cause serious injuries during their implementation.

Sharpening a chain is not as difficult as it seems at first glance. Any person, after studying the process of straightening chains, can independently sharpen the cutting set of his tool. Even if the first time you manage to do it not very well, you shouldn’t despair, because... With each next attempt, the result will get better and better.

What devices are there for sharpening chainsaw chains: features of manual sharpening, use of a machine

In order for the tool to effectively cope with its task, it must be provided with appropriate care. You need to be especially careful with different saws, as they can quickly lose their sharpness.

You can restore the original cutting properties of a saw tool by using sharpening devices such as a needle file, a small machine or a special attachment for a drill. If we are talking about a chain for a chainsaw, then sharpening it will not be so easy. It is the features of this process that this article will focus on.

What are chainsaw chain teeth?

One of the main characteristics that distinguishes a gasoline saw chain is its complex geometric shape . Traditional incisors are usually made in the form of a triangle or a highly elongated oval. As for the teeth of a chainsaw, they have a more complex configuration.

Each tooth is formed by two incisors , which are at right angles to each other. The first incisor resembles a regular tooth in appearance. Its main task is to make cuts in wood.

After this, another cutter is used, which is made in the form of the letter G. It is not by chance that it has this shape, since due to its design it removes chips from the wood and provides a wide cut , which prevents the chain from being pinched.

Therefore, how easy and high-quality the sawing work will be depends to a large extent on the chainsaw chain. This is a good reason to consider its design in more detail.

Indeed, in the overwhelming majority of cases, the sawing tool begins to cut worse due to the fact that the chain is already in a state where it cannot cope with the task.

Technical parameters of chainsaw chains

It should be noted that the chain pitch directly affects the performance of the sawing tool. Therefore, to perform a large amount of work, it is recommended to choose a chain with the largest possible teeth .

Using a tool like this, the work can be done with less effort and quickly.

Technical characteristics that are important to pay attention to when choosing chains for chainsaws:

• step interval;
• number of links;
• their thickness;
• planned type and scope of work.

The smallest step is 1/4. If a chainsaw is equipped with a chain with this pitch, then it is suitable for performing simple household tasks . She will do an excellent job of cleaning fruit trees, but at the same time she will not be able to cut firewood.

Products from many European and Chinese manufacturers most often have a chain with a pitch of 0.325 and 3/8. A chain with a similar interval can cope with a wide range of work , including the removal of fairly thick trees reaching a diameter of more than two meters.

Steps 0.404 and 3/4. Chains with such an interval are usually equipped with tools for industrial use . Choosing a chain with a pitch within this range is advisable if the sawing tool is needed for frequent sawing of forest, as well as harvesting thick logs or performing tree cutting work.

As the number of links increases, the process of sawing wood becomes easier. Thus, a parameter such as the number of links also needs to be taken into account. However, a more important characteristic is their thickness, which can have the following values: 1.1 mm; 1.3 mm; 1.5 mm; 1.6 mm.

If the tool is intended for domestic use, it is recommended to choose a chain whose teeth have a thickness of 1.3 mm . If a buyer is looking for a tool for logging, it is recommended to choose a chain with a tooth size of 1.5 mm.

In cases where the chainsaw meets the tasks that need to be solved in all respects, however, there is a drop in performance, we can conclude that the reason for this is a dull chain . If poor performance is due to other problems, then the only correct solution is to buy a new chain.

Sharpening chainsaw chains manually

Among all the available methods by which you can give chainsaw teeth their original sharpness, sharpening with a file is considered the simplest. However, first you need to prepare:

1. Remove the chain from the saw.
2. Clean off any remaining oil, sawdust and other contaminants.
3. Take a dry cloth and walk along the chain to remove small debris.
4. Select suitable files (small and large).
5. Start the sharpening procedure.

Particular attention should be paid to cleaning the chain from oil residues and other contaminants, which should be carried out most thoroughly. The need for this operation is due not only to the measure of protection against the transfer of dirt to hands and clothing. A well-cleaned chain will allow you to better see it and its links.

There are common situations where chips can get stuck between the teeth or in them. And this is one of the reasons for the deterioration of tool performance.

Sharpening features

Considering that the base of the tooth is formed by two separate elements, the process of sharpening each of them will be carried out differently. The cutting edge located at the top provides for a one-sided conical sharpening .

It is important to maintain the optimal sharpening angle, which should be in the range from 15 to 30 degrees. Moreover, it is advisable to maintain a minimum sharpening angle, since this will simplify the entry of the saw into the wood.

It should be taken into account that as the angle decreases, the metal becomes thinner, and this will speed up the process of steel dulling. When choosing a sharpening angle, it is also necessary to take into account the type of wood that you plan to saw.

• To work with hardwoods, such as oak or larch, the sharpening angle must be maintained at 30 degrees.
• When working with soft woods, such as pine, fir and many types of garden trees, a sharpening angle of 20 degrees is considered optimal.
• If the tool is used to trim not very thick branches of fruit trees, then a sharpening angle of 15 degrees will be sufficient.

The second tooth, which is a guide, usually has double-sided sharpening . Here you don’t have to focus on maintaining the angle of inclination of the cutting edge. It must be remembered that it should not be too small or large. It is best to stick to the average value - 30 degrees.

Among the elite models of the tool, there are those that have a chain with teeth equipped with a reinforced blade . You can tell whether a chainsaw has such an amplifier by its appearance.

Usually on the edge of the tooth you can see a fixed special cutting edge , which has a completely different color and texture. Having identified this element, you can refuse to sharpen the tool chain.

This will be correct, given that such amplifiers contain ultra-strong alloys that cannot be sharpened by hand. If the chain has lost its sharpness, then the only solution is to buy a new one.

The process of sharpening a chainsaw chain with a file

To sharpen a chain using a file, you must perform the following steps:

• prepare needle files of suitable sizes (small and large);
• place the chain in a vice and fix it in it; the vice can be replaced with a clamp;
• start sharpening the upper cutting edge;
• the operation itself should be performed in the direction from the body of the tooth to the tip;
• start sharpening the guide edge;
• The sharpening tool must be moved in the direction from the body to the tip, changing sides from time to time.

During the sharpening process, it is necessary to maintain the specified direction of movement of the file, since, otherwise, this will lead to even greater dulling of the chain. Moreover, this rule works regardless of whether a manual or automated device is used for sharpening.

Sharpening chainsaw chains on a machine

Sharpening the chain of a medium-sized tool is quite lengthy and takes at least 6–8 hours. In this regard, it makes sense to use electrical appliances to solve the problem.

If sharpening is performed using a drill, then it will have to be used in combination with a conventional “sharpening stone” attachment. But you need to make sure that the width of the nozzle matches or slightly exceeds the plane of the tooth blade. Otherwise, the chain will be sharpened unevenly.

In addition, to ensure high-quality sharpening, it is necessary to use a sharpening stone , the surface of which should not have unevenness, as well as any other defects.

The algorithm for preparing for sharpening of this type is as follows:

1. You need to loosen the screw that adjusts the chain clamp.
2. Then you need to adjust the chain so that its teeth are directed towards the sharpening element.
3. Finally, it is necessary to fix the equipment at a certain angle.

If you use a standard stone for sharpening, you will have to grind it to the required size or use special grinding stones . The latter are smaller in size compared to sharpening ones, made of less durable material and quickly exhaust their working life.

At the same time, due to the lower strength, overheating of the metal is eliminated, and this allows the steel to remain just as strong. If the work is done using a sharpening stone, then it is necessary to take pauses between every 2-3 sharpenings of the tooth - these are necessary to cool the stone.

unacceptable to use water for artificial cooling ; here the option is to use a fan or apply a sharpening stone to pieces of ice previously wrapped in rags.

Considering that the sharpening machine has quite a lot of power, it is advisable that the sharpening operation on it be performed by professionals. If you use a regular household sharpening machine, it is able to return its former sharpness only to the upper cutting edge.

This limitation is due to the size of the machine. However, if you use the machine only to sharpen half of the teeth, then this work will take half as much time.

Expert advice

If you are interested in a sharpening and grinding machine in order to perform a number of other operations in addition to sharpening knives and saws, then it is best to buy a compact low-power unit , which will be similar in its characteristics to a dentist’s drill.

This machine is not only smaller in size but also has different functions as it can be used for carving wood, metal and stone. If necessary, it can be improved so that it can be used to sharpen small parts.

In stores, such units from the budget category are offered at prices starting from $300 . In this regard, it makes sense to consider this option only if you need such a machine for regular use.

A special group is formed by special machines for sharpening chainsaw chains. However, due to the high cost, the purchase of such installations for the average consumer will be impractical.

Each tool has a limited working life, so to extend its service life it is necessary to take certain measures. In relation to a chainsaw, this is chain sharpening.

Naturally, not in all cases this operation will allow the sawing tool to return to its previous level of performance. Therefore, you first need to understand the reasons for the deterioration in performance, after which you can move on to choosing a sharpening device.
