How to properly sharpen a chainsaw chain with a file by hand

How to sharpen a chainsaw chain with your own hands: 3 proven methods

The quality of sawing wood with a chainsaw largely depends on the sharpness of the chain. How to sharpen a chainsaw chain with your own hands at home? We will tell you about three good ways.

The speed and quality of sawing wood with a chain saw depends on the sharpness of the chain. It needs to be sharpened from time to time. How can this be done? We will tell you about three reliable ways in which you can sharpen a chain with your own hands. One of them allows you to sharpen the chain right in the field, while the other two require a special tool and electricity.

Sharpening the chain with a file

This type of sharpening can be used directly in the field. It requires a round file, a holder for it (clamp) and a vise for clamping the tire.

To sharpen with a file, you need to perform the following manipulations:

  • Clamp the tire in a vice. If you are in landing and did not take a vise with you, then you can clamp the tire by resting it on the log.
  • Place the clip with the file on the chain so that it creates an angle of 30 °.
  • With light movements forward (away from yourself), we sharpen the tooth. With a new file, it is enough to make 5. 7 movements. If the file has already been used several times, then more movements will be required.
  • After the tooth has been sharpened, remove the file with a clip and scroll the chain to the next tooth. After passing all the right teeth, turn the saw (or change the position of the file) and sharpen the left teeth.

Some file holders have a filed template on which the turning angle is already indicated. So you do not have to “figure out” this angle. But from experience we will say that you need to practice well until it turns out to sharpen the chain perfectly smoothly with a file.

Chain design

The saw chain consists of the following elements:

  • Left cutting tooth.
  • Right cutting tooth.
  • Cutting depth stop.
  • Leading link.
  • Rivet.

In order for the chain to saw well, it is necessary to sharpen each tooth on the left and right sides. However, in order not to spoil the sharpening, it is important to know what shape our teeth on the chain are. There are two common forms of saw teeth:

  • Chipper. This is the more common tooth shape and is found in almost all chains. Here the profile is somewhat rounded, so it is much easier to sharpen it with a round file. In practice, however, the chipper dulls a little faster than the chisel.
  • Chisel. The cutter profile in this case looks like a seven. Such a cutter has a rather small contact area when it comes into contact with wood, so it encounters less resistance. For this reason, in one cut, he makes a greater depth of cut, which means that the speed of cutting a log will be higher (in comparison with a chipper). But sharpening it without damaging the edge is much more difficult.

Method 1

We install the chainsaw on the table, and clamp the tire with a vice so that it does not move during operation. We set low rpm on the angle grinder (if there is only smooth adjustment, then slightly press the start button). We direct the disc at an angle of 30 ° relative to the plane of the tooth and tilt it slightly (as shown in the photo). Press on the tooth with light, soft movements.

With this method, the main thing is not to overheat the tooth and not to grind off too much metal. Ditching teeth, sharpening in this way, is much easier than with a hand file, but the sharpening speed increases significantly.

Saw chain sharpening methods

There are three ways to sharpen your saw chain effectively:

  • File.
  • Grinder.
  • Sharpening machine.

HOW TO SHARPEN A CHAINSAW CHAIN PROPERLY.

Sharpening the chain with a grinder

If you have a grinder, then you can sharpen the chainsaw chain much faster. It is best to use a small grinder with a 125th circle. Sharpening is done at low speeds. There are two ways to sharpen angle grinders.

Method 2

In this case, it is the grinder that needs to be fixed immovably. Can be clamped in a vise or screwed to a workbench with a bracket. Sharpening is done as on a conventional grinding wheel. We hold the chain with our hands and turn it so that the tooth sharpens at an angle of 30 °.
With this method, the hands get tired less, since you need to hold the chain, and not the grinder. However, the chance of getting injured increases significantly. We recommend using this method infrequently or not at all, since safety is still more important than speed or quality of sharpening.

Sharpening with a file

The first thing you need to sharpen the chain, or tweak it a little, are special files.

How to sharpen a chainsaw chain with your own hands

Everyone knows that the saw chain, which is used in chainsaws, needs to be sharpened periodically, but not everyone knows how to do it correctly. Determining that the saw requires sharpening the chain is very simple, for this you need to inspect the sawdust, and if they consist of fine dust, then the tool needs to be sharpened. If it is impossible to sharpen, it is worth replacing it with a new one.

The use of a chain that is not sharpened can lead to overheating of the engine and the formation of scoring on the cylinder.

We will analyze the main ways with which you can, without problems, sharpen the chain on a chainsaw.

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 diameter of the rounding 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, due to the fact that they have a small tooth. For professional models, more powerful chains with a larger tooth 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 noticeably reduce the speed of work and, just like in a situation with a blunt chain, can lead to overheating of the saw motor due to insufficient load on the motor. This work is done with a flat file.

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

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

  • Sharpening with a file (the most common method of sharpening, because it allows you to sharpen the tool directly at the cutting site.)
  • Sharpening using a special machine (this method is used in service centers, but can also be used on a personal farm)
  • Sharpen using a grinder. To sharpen in this way, certain skills are required. Uncommon method, because it is quite difficult to sharpen with angle grinder correctly.

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

Description of the sharpening process with files

The first thing to start with straightening the saw chain on the saw is placing the tool on a flat surface 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, it can be cracks, completely broken off teeth. After inspection, you need to set the brake in working condition, thereby blocking its movement on the tire.

The chain must be taut when sharpening with a file.

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

The chain is sharpened by moving the file from the inside of the tooth outward. 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 sharpened tooth should be located approximately in the middle of the tire, this is necessary for the convenience of work, during the sharpening process, you need to move the chain along the tire, not forgetting to set the brake to the working position each time.

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

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

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

Tool holders are also handy if you don’t have sufficient sharpening experience. Experienced sharpeners do not use holders for sharpening, but can only use special devices that support the file.

Another sharpening device is a hand-held saw chain straightener. It uses a regular file as a sharpening tool, which can be replaced independently. The machine is mounted directly on the tire, it also has the ability to adjust the angle of sharpening of the tooth and a special stop that holds the sharpened tooth.

Manual sharpening machine, perfect for beginners. Along with electric models of sharpening machines, manual has its undeniable plus in the form of a low price. Depending on the manufacturer of the hand-held machine, their appearance may differ, but the principle of operation is the same for all.

The depth of cut is adjusted with a flat file, so that there is a difference between the upper cutting edge of the tooth and the height stop.

As you can see from the figure, the depth gauge is grinded in such a way as to bring the gap indicator to the factory value. Below is a table that shows the main values ​​of the angles, as well as clearances for the most common types of chains.

As a rule, the size of the gap is corrected using a special die. It is installed on the chain during sharpening, after which the depth gauge is grinded.

Electric grinding machines

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

The saw chain is installed in a special guide, which is mounted on the basis of the turntable and has a special retainer to hold the sharpened tooth. The latch can be moved horizontally. An electric emery is installed at an adjustable angle to the sharpened tooth, which is turned on by the operator by pressing the start button. The immersion depth of the emery, as well as the angle at which the sharpening is performed, can be adjusted. The dive itself is performed by the operator. The chain is straightened with a special sharpening wheel, which can be changed if necessary.

How to sharpen with angle grinder (grinder)

The method of sharpening the saw chain using an angle grinder, the least common due to its insecurity. In order to straighten the chain teeth using a grinder as a sharpening tool, you must install it in a vice and clamp it securely. Then the tool is switched on and the sharpened edge of the tooth is placed on the rotating surface of the disc. A tooth sharpened in this way can differ significantly from that sharpened with a file, because in the process of dressing using a grinder, it is quite difficult to control the sharpening angle.

A big disadvantage can be considered the possibility of a notch with the grinder disk of the eyelet for attaching the connecting link of the chain, which in the future will lead to a rupture during work. If, in the process of carrying out work using a chainsaw, the need arose for sharpening, it is better to use a special tool than to come up with various tricks that can result not only in financial losses, but cause serious injuries during their implementation.

Sharpening the chain is not as difficult as it seems at first glance. Any person, after studying the process of straightening chains, is able to sharpen the cutting set of his tool on his own. Even if the first time you manage to do it not very well, you should not despair, because with every next try, the result will be better and better.

How to properly sharpen a chainsaw chain with a file

Templates and patterns must be fixed on the area to be treated. They will give the right direction to the file, making the process easier. When all the preparatory work has been done, you can proceed directly to sharpening the chain.

According to the rules, it is necessary to sharpen the teeth in one direction, then in the other. Work begins with light clicks with a file in the direction away from you, the pressure gradually increases. Reverse file movement. without pressing. The circular tool must be continuously rotated along its axis. The chain is sharpened by movements from the inside of the tooth to the outside. In this case, the file must be located parallel to a special mark on the chain, which is applied by the manufacturer to indicate the standard sharpening angle.

The sharpened tooth should be located approximately in the middle of the tire, this is necessary for ease of work. In the process of processing, you need to move the chain along the tire, not forgetting to set the brake to the working position every time.

The angle of inclination of the tool should be right, and the angle of sharpening of the chain of the chainsaw horizontally. sharp, while its changes are allowed in the range from 10º to 30º. The smallest tooth in the row should be taken as a basis. Turn the tire over and do the same job for the teeth that go in the opposite direction. The disadvantage of this sharpening method is the large time consumption.

Sharpening the chain with a file

You can insert a round file with a broken handle into the chuck of an electric drill or screwdriver. You will get a very convenient mechanized sharpening device.

Tooth configuration and sharpening angle of the chainsaw chain

The chainsaw tooth has a complex configuration, which depends on the direction of movement of the chain. The tooth has two working edges: the lateral one, located perpendicular to the axis of movement of the links, and the upper one, which is at a certain angle to the direction of movement of the chain. Each tooth has a cutting depth stop. It determines the height of the chips to be removed. The main cutting force falls on the cutting edge. The sharpening angle of the tooth determines the quality of the tool.

Important! The configuration of the tooth should be checked regularly, especially before starting long-term work.

Each saw model has its own cutting edge pitch, the value of which for household and semi-professional models is associated with the power of the unit and the drive torque. For rip sawing, the pitch is taken less (eg 0.325 inch). In this case, the work performance will decrease, but the required effort will also decrease. When felling trees with a large trunk diameter, the engine power does not exceed 2500 W. The thickness of the cutting edge for most chainsaws is set to 1.3 mm.

The height of the chain profile is either 0.625 mm or 0.762 mm, and a low profile is used for household saws. At the same time, the vibration of the saw increases slightly.

The edge of the tooth for longitudinal cutting should be very sharp and have an angle in the range of 6º… 12º, for transverse. up to 25º… 30º.

In the first case, sharpening should be done more often, since an unacceptably small angle of inclination of the tooth contributes to its rapid chipping. This is especially noticeable in links that are made of structural alloy steels containing silicon and manganese, for example, 40KhGS or 35KhGSA.

Features of sharpening saw chains

The saw chain is a set of cutting teeth of complex configuration interconnected by means of hinges. When processing the chain, it is necessary to ensure the uniformity and uniformity of sharpening of all teeth, maintain the correct angle of the cutting edge, and maintain the desired configuration of the tooth. To solve these problems, there are several ways of sharpening, as well as many different tools and devices.

The saw must be sharpened on time, otherwise you can get a lot of trouble. a decrease in productivity, a deterioration in the quality of a cut, accelerated wear of the mechanism, even injury.

How to sharpen a chainsaw chain on a machine

Sharpening a chain on a machine is much faster and more accurate than with your hands. There are many different electric sharpeners on the market. Household units are compact, operate on a 220 V network. Abrasive wheels are easily replaced on them, they can be easily rebuilt to different chain parameters: tooth pitch, upper edge thickness, sharpening angle. All machined cutting edges are the same. The process is going fast.

How to sharpen a chainsaw chain at home with a file

A tool with an exceptionally round section will help to properly sharpen the chainsaw chain with a file. File parameters are determined by the dimensions of the saw itself. It is important to know the pitch of the teeth. One round sharpener is not enough. For sharpening and dressing chains, two types of tools are used. The first is a file with a circular cross-section with a diameter corresponding to the diameter of the rounding of the working edge of the saw tooth. A flat file is required to cut the depth gauge on the guide tooth.

Sharpening can be done manually using a round file with a working diameter of 4. 5.5 mm. It is imperative that the tool is correctly positioned in relation to the tooth being sharpened. The upper edge of the working part of the file is approximately one fifth higher than the upper edge of the workpiece. The tool is held perpendicular to the chain axis at an angle of 25º… 30º to the upper edge of the tooth.

For sharpening saw chains of household tools, round files with a diameter of 4 and 4.8 mm are used, since they have a small tooth. For professional models, use more powerful chains with a larger tooth. Therefore, files with a diameter of 5.2 and 5.5 mm are needed.

You will need a flat file to sharpen the limiter, and a hook that removes the resulting sawdust to clean the work area. There are also commercially available special holders, on which the lines of the direction of movement of the file relative to the axis of the chain are graduated. The holder can be mounted on top of the tooth, resting on its upper edge. Since its height is adapted to a certain chain pitch, this device should be selected in relation to chainsaws of specific models and brands. The minimum required set in order to obtain the correct angle of sharpening the chain by hand is shown in the photo.

A set of sharpening tools and accessories

Manual sharpening saves material resources, allows you to work in the field. First, place the instrument on a level surface. If the work is done in the forest, trimming a large diameter log is a good choice. Next, you need to inspect the saw chain for any defects, it can be cracks, completely broken off teeth. After inspection, you need to set the brake in working condition, thereby blocking the movement along the chain bar, which must be tightened during sharpening with a file.

A file for sharpening chainsaws: types and tips for choosing

The diameter of the round file is selected according to the pitch of the saw chain. The pitch values ​​of 1.3 and 1.6 mm correspond to files with a diameter of 4 and 5.2 mm. A flat tool will be required to reduce the height of the stops of the cutting links.

Do-it-yourself chain sharpening for a chainsaw using a grinder

Experts strongly recommend not to use this method for inexperienced craftsmen. He’s pretty dangerous.

But if there is no other way out, then you must follow the safety rules. The grinder must be installed in a vice and clamped securely. After switching on the tool, bring the edge to be sharpened to the rotating surface of the disc. Since it is impossible to maintain a constant sharpening angle with the use of a grinder, a tooth sharpened in this way will differ significantly from a filed one. In addition, there is a risk of notching the tooth attachment ear with the grinder disc.

How to sharpen a chainsaw chain: methods, tools and accessories

A good master must have a good tool and always be on alert. This applies to any skilled person. All cutting and sawing devices must always be properly sharpened. This requirement is also relevant to such complex tools as saws, especially electric and gasoline. In today’s review, we will figure out how to sharpen a chainsaw chain, what you need to know for this in order to do the job efficiently.

Sharpening with a file

The first thing you need to sharpen the chain, or tweak it a little, are special files.

How to properly sharpen a chainsaw chain with a file by hand

Everyone knows that the saw chain, which is used in chainsaws, needs to be sharpened periodically, but not everyone knows how to do it correctly. Determining that the saw requires sharpening the chain is very simple, for this you need to inspect the sawdust, and if they consist of fine dust, then the tool needs to be sharpened. If it is impossible to sharpen, it is worth replacing it with a new one.

The use of a chain that is not sharpened can lead to overheating of the engine and the formation of scoring on the cylinder.

We will analyze the main ways with which you can, without problems, sharpen the chain on a chainsaw.

Hand-operated machines

The design of such a machine is similar to a bow saw. Only where the saw blade is located is the round file. With such a machine, you can sharpen and straighten the teeth, adjusting the proportionality of the upper edges to the smallest (control) size. The mechanism allows you to accurately set the parameters. After adjusting the “control” tooth, sharpening is carried out in two or three movements. And then the transition. to the next tooth.

When it is necessary to grind off the stopper, we change the round file to a flat file.

Advantages of the method: Allows you to sharpen teeth, including those that have lost their original shape, in a high-quality, convenient and without large physical costs.

Disadvantages: The price of the tool and the distance from the possible site of the saw operation.

“After finishing the“ sharpening procedures ”, blow the chain with compressed air (from a compressor or pump) and put it briefly in clean engine oil. Of course, almost no one does such events, but for the chain, they will only benefit. “

What to choose for sharpening is up to you. This is due to how often you use your chainsaw. From the accuracy of handling it. From the quality of the purchased chain. And, of course, from the opportunity to spend a certain amount. It is impossible to compare the methods, because as the German proverb says. “apples should be compared with apples”.

Possible ways and methods of sharpening the chain

How to understand that the chain is dull

  • Increased physical effort;
  • Sagging (stretching) of the chain;
  • Vibration and “braking” cutting passage;
  • Inaccurate sawing and change in the type of sawdust (they become uneven with sharp “needle” edges, small and dusty). This is already the answer to the test.

“In the opinion of the experts, and in my opinion too: well-sharpened teeth are more important than engine power.”

Why dull? The reasons are generally known, but I will name the main ones:

  • Intense or voluminous work;
  • Accidental contact with stone, earth, hard knots, etc.;
  • Mishandling (broad term).

How to sharpen with angle grinders

The method requires skill and skill. Unlike a sharpening machine, there are no stops here. The master is required to be accurate and comply with safety rules. It is better for experienced people to use the method. The grinder (angle grinder) is previously securely attached to a table or other stable place.

Better to make a special clamp for this. After fixing, check if there is vibration, turning on the instrument in the test mode for a few minutes. If the conditions are satisfactory, you can start work. Directly sharpening chains for chainsaws with your own hands with a grinder is carried out by supplying a link to the abrasive wheel.

In conclusion, we can say that no matter how sharpening the chain for a chainsaw is done with your own hands, the main thing is the accuracy and accuracy of the master. With manual processing, corner errors and uneven grinding of the metal are possible, and with machine processing, there are risks of injury.

“The lumberjack working with a blunt ax was advised:. Sharpen the ax.

He replied:. There is no time. It is necessary to cut down the forest. “

Greetings to all readers!

Today I decided to tell you about the tool, without which, as it seems to me, today it is simply impossible. A good tool should work well, and this largely depends on its owner.

Cleaning the autumn garden, preparing firewood for winter, building a bathhouse, repairing a wooden fence will require not only time and desire, but also the readiness of the “cutting” tool. If it is a chainsaw, then it must be properly sharpened.

Of course, there are paid specialists, and you, for example, have extra money. But we know that such a procedure is performed periodically and therefore a natural question arises: how to sharpen a chainsaw chain at home? I’ll tell you about that. Go!

In this article, you will learn:

Chainsaw teeth

Chainsaw teeth have a specific geometry. You need to understand and know what part of them should be sharpened. In general, the “logic” of cutting wood resembles a plane.

The cutting surface has two edges. One is lateral, the other is slightly beveled. The cutting depth limiter adjusts the thickness of the chips. Let’s take a closer look. The elements of the cutting-working link are arranged as follows:

  • Base with axle holes;
  • Tooth scapula;
  • Cutting depth limiter;
  • End face of the blade (placement. vertical);
  • Upper edge of the blade (placement. horizontal);

Sharpened edge Dull After touching the ground

After sharpening, the height of the stop and the angle of the sharpened working edges should not differ greatly from the parameters specified by the manufacturer. This is an important condition and it needs an “eye and eye” behind it. Otherwise, the saw will not work as expected.

Do not over-grind or change the location of the links. The normal operation of the instrument depends on the identity of their location. Otherwise, increased stress on the chassis, tire and engine is likely. The cut can be crooked. There is also a small chance of breaking the circuit.
