Chainsaw Sharpening Machine

How to sharpen a chainsaw chain with your own hands. Step-by-step instruction

Bringing the chain into working condition has its own characteristics. They are determined by the configuration of the tooth. It includes two edges, one at the top and the other at the bottom. over, the edge located towards the top has a slope at a given angle. In fact, the tooth, both in geometry and in the principle of operation, is similar to a blade from a carpentry plane.

For competent sharpening, the master must understand the structure of the tooth.

When to sharpen and how to find out

After examining the saw chain, the foreman decides whether it is time to sharpen the tool or not.

As a rule, the saw chain loses its performance during intensive work. Things can get to the point that the chain will have to be resharpened several times in one day. The contact of the saw with the ground can also be the reason. In fact, quite a few times to strike the saw chain on the ground and you can stop all work. The chainsaw will simply stop going into the tree. By the way, one of the signs of a dull saw is the appearance of small chips.

Dull chainsaw chain

The earlier measures are taken to sharpen the chain, the longer it will last. It is quite easy to understand when regrinding is required. The feed change will occur. A chain with correctly sharpened teeth will retract even with a little effort, but if you have to exert a greater feed force during operation, then this means only one thing, the teeth have lost their sharpness.

The use of a dull chain is not permitted. By the way, this is a safety requirement. And the process will require significant muscular effort from a lumberjack. As a result, this leads to a decrease in the quality of the cut, an increase in the amount of fuel used and an accelerated development of the chain.

Saw design

For a better understanding of what a chainsaw is and how it works, it is advisable to know how it works.

By the way, it would be more correct to call the cutting tool of a chainsaw. a saw chain.

The first saw chains appeared at the beginning of the 20th century. The designers began to rack their brains, they simply mounted the teeth on the chain, which quickly lost their performance. In appearance, they resembled those that stand on hand saws on wood. Sharpening such a chainsaw was very difficult. But, multiple attempts to create the perfect saw chain were crowned with success only in 1947.

This chainsaw has L-shaped links. Modern chains are, in fact, the direct ancestors of this development.

If during the work the cutting speed began to decrease, the chainsaw in the hands of the master begins to “walk”, then most likely, the saw chain has lost its operational properties, that is, it is dull and it is necessary to take measures to restore them.

File

The file can be used to carry out the work in question. A file is used to remove the required metal layer from the surface. For this case, a special set was created:

• Round file with an unusual holder.
• Flat file required to adjust the depth limit.
• Hook.
• Special template.

The round file holder is created together with the scribe lines that are used to position the tool correctly. The plate itself, during operation, comes into contact with the depth gauge and the surface of the blades, and the file goes around and removes the metal layer. The use of a special holder with a file allows you to ensure the correct fit of the tools to the work surface. It is worth using only the file that is designed to perform such work.

Angles of inclination when sharpening with a file

The rules for carrying out work include:

• The same number of movements should be done.
• It is necessary to control the force of pressure on the surface during its processing.
• The template, which is used together with the file, allows you to observe important sharpening values.

With different lengths, there is an uneven course and the formation of cracks in the material. If the length indicator is not the same at the time of the start of processing, then all cutting teeth are sawed according to the indicator of the smallest of them.

When to do the work?

With intensive use of the chainsaw, sharpening is carried out quite often, often several times in one day. Particular attention should be paid to the fact that the meeting of the chain with the ground speeds up the process significantly. Therefore, chainsaws must be used in such a way as to exclude the possibility of contact between the chain and the ground. After several contacts, the chips will be very fine, and the chain will go deep into the material only slightly.
When considering this issue, it can be noted: the more often you have to sharpen the chainsaw chain, the less metal layer is removed. Also, if you sharpen often, then the service life of the cutting element of the chainsaw will increase significantly. The main condition can be called the correct execution of the work, if you do it yourself. The procedure can be performed correctly only if there is a special machine.
Significant feed force can be called a sign that the cutting element of a hand-held chainsaw is dull. Correct sharpening of the chains determines a significant decrease in the feed force indicator, that is, the chainsaws enter easily with a slight pressure. Another sign of the need for sharpening chains can be called the production of very small chips.
Sharpening the chainsaw when the signs in question appear is mandatory. Sharpening of chains is carried out in order to reduce a lot of stress in the body, to reduce the cyclic load indicator, fuel consumption. Also, if you do not sharpen the teeth of the chains in time, there is a possibility of increased wear of all nodes, as a result of which there is a reduction in the service life of the manual chainsaw.

Geometry features

In order to sharpen correctly with your own hands, even if a machine is used, you should know the geometry of the tooth. Its constituent elements include:

• Scapula.
• The main link.
• Depth gauge.

In this case, the tooth scapula consists of the following elements:

• End blade.
• Upper blade.

It is necessary to sharpen correctly with your own hands, taking into account that the end and top blades must be located correctly relative to each other to ensure the best cutting performance. The back of the tooth forms a certain angle of the upper blade. A similar angle is formed to cut the blades into the material. Do-it-yourself sharpening should also take into account the fact that the back of the blade has a narrowing. this design feature forms the angle of the end blade. It is created to provide side cutting of the chips.

Chainsaw chain tooth

The sliding surface and the blade end form the rake angle. In this case, the angle has a fixed value, it varies from 60 to 85 degrees.
If you sharpen your teeth with your own hands, it is worth considering that it is the upper blade that is the main one, and the angle formed by it is the most important angle.
Summing up, when considering the issue of geometry features, we note that the sharpening angle can vary depending on the conditions of use. The main rule that should be observed when sharpening a tooth with your own hands is the following: the higher the angle, the greater the performance of the chainsaw, but a decrease in the indicator provides a smoother blade movement, reduced vibration and increased service life. Sharpening is worth considering that the indicator should be in the range from 25 to 35 degrees. An exception can be called the version of the blade, which is designed for longitudinal cutting. many manufacturers of the cutting element of the chainsaw can withstand 10 degrees.

Why does the tool become blunt?

Each chainsaw has a certain period of durability. This is the name of the time from the start of work with a new tool, until it becomes inoperable.

The destruction or wear of a cutting tool designed for woodworking occurs due to the influence of a set of forces arising during the cutting process. One of the key ones is the friction force. Dullness of the saw chain occurs due to prolonged work, due to the use of the chainsaw for other purposes

The amount of wear can be defined as a measure of weight, measured in milligrams. Wear is a parameter that shows the change in the characteristics of the shape and dimensions of the cutting blade. Changes in geometric parameters that occur during cutting, and at the same time there is no linear wear, is called bluntness.

There are parameters on the basis of which a decision is made about the possibility of further operation of the tool. In particular, when examining the teeth of the saw chain, it is necessary to pay attention to the edges of the front and rear surfaces, the height of the blade, and the wear area. If they are in unsatisfactory condition, it means it’s time to sharpen the chainsaw.

Signs that the saw has lost its sharpness include the following:

• Reduced chip size.
• Using more effort to get the job done.

Tips and tricks on how to sharpen a chainsaw at home

It is permissible to use a file for sharpening, but one must understand that such an operation of the saw will require certain skills from the master and, of course, patience. To sharpen each tooth, it is necessary to have flat and round files on hand. To sharpen a tooth, without using additional equipment, it is necessary to maintain the basic sharpening slope. Only 2-3 passes with a file are enough for sharpening, then there is no point in inventing some kind of equipment for fixing the tooth in a certain position. To sharpen the upper edge, the file must be held at the required angle during operation. The restoration of working capacity begins with preparation, namely, from the working edges, it is necessary to remove all nicks.

If everything is clear with the corners of the teeth with straight parts of the structure, then the edge located on the side and its working slope cause certain difficulties. To edit them, you must use a file with a round cross-section or a file of small dimensions. The sharpening of these tooth elements is performed at the required angle.

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 one 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 located about a fifth above 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 mowing line is graduated with the direction of movement of the file relative to the chain axis. The holder can be installed 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.

How to sharpen a chainsaw chain correctly on a machine

Sharpening the chain on the 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.

Do-it-yourself chainsaw sharpening with an angle 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 angle 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 using an angle grinder, a tooth sharpened in this way will differ significantly from a filed one. In addition, there is a risk of notching with the disc of the angle grinder of the tooth attachment ear.

Chainsaw chain sharpening file: 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 cutting link stops.

Hand-operated machines

There are devices designed for sharpening, but without an electric drive. These are manual saw chain straighteners. A regular file is used as a sharpening tool. The machine is attached directly to the rail. Special stop that holds the sharpened tooth. Sharpening angle can be adjusted.

The photo shows a stationary machine in which the grinding disk rotates with a handle through a gearbox. The saw chain itself is clamped in a machine vice. The machine has a base that can be screwed to the table.

Manual Chain Saw Sharpening Machine

A machine for sharpening chainsaw chains: selection criteria, design features, technical and operational characteristics of equipment, the principle of operation of manual and automatic devices, an overview of popular models of sharpening installations.

Features of sharpening saw chains

The saw chain is a set of cutting teeth of complex configuration interconnected by means of hinges. When processing a chain, it is necessary to ensure uniformity and uniformity of sharpening of all teeth, maintain the correct angle of the cutting edge, and maintain the desired tooth configuration. 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 cut quality, accelerated wear of the mechanism, even injury.

Electric chainsaw chain sharpener

The main part of the machine is an electric motor, on the shaft of which a grinding disc is installed. The controls are located on its handle. There is a clamp for securing the machine to the chain. The spring clamp provides adjustment of the pressing force on the sharpened element. Differentiated clamping provides for the self-centering of the product in the machine. For the safety of work there is a folding safety guard.

Electric saw chain sharpener

A saw chain is installed in a special guide mounted on a turntable. The retainer holds the sharpened tooth, to which electric emery is installed at a predetermined angle. The operator turns on the engine and controls the immersion of the disc

angle grinder. a good alternative

Professional lumberjacks consider this method to be primitive and labor intensive. It is used as a last resort, since the angle grinder cannot be fixed to the template. For this reason, it is very difficult to achieve control over maintaining a constant angle and depth of sharpening.

The tire is securely fixed in a vice to prevent its movement during operation. You should not attach a new cutting disc to an angle grinder, it is better to use an old disc 1.5-2 mm thick.

It is better for beginners not to use this method at all. they will be more whole. There is a risk of serious injury to yourself. In addition, there is no way to do without the skills of working with such equipment.

Sharpening rules

Sections of the same type of each link must be uniformly processed. Otherwise, if in any one area there is an excessive sample of metal, then ultimately this leads to an imbalance, uneven stroke and jerks during the operation of the chainsaw. The load on the mechanism increases many times, which in turn threatens to break the chain.

Therefore, to carry out the operation at the required angle of sharpening the chain of the Stihl 180 chainsaw (as well as any other tool) should be done with extreme caution, avoiding excessive force. The procedure itself is performed sequentially, that is, you need to start on one side, then finish on the other.

In some cases, you can observe that one or more cutting edges have sharpened more. This happens when the chain on its way ran into a knot, which is found when cutting hard wood. Then it is necessary to determine which of the teeth was grinded most of all and to equalize all the other links by it.

After sharpening is completed, blow the chain with air from a compressor or pump, and then place it in a container with engine oil for a short time. Usually few people do this, but it will be useful for the chain.

Sharpening methods

To sharpen a tool, you can turn to the services of craftsmen who not only know what angle of sharpening chainsaw chains is needed, but also do all the work quickly and at a professional level. As a rule, the cost of such services is not so high, but the quality, on the contrary, is very high! This option is suitable for those lovers of forest felling who have no desire to tinker with their tools.

It will be interesting for everyone else to try their hand at such a thing. Professionals in this regard always choose automatic equipment that is characterized by maximum efficiency and accuracy. Of course, not every lumberjack can afford to purchase it, and therefore they get by in different ways. And here, among many amateurs, discussions are being held on which technique is better to give preference to:

• manual;
• alternative;
• modern.

Do not neglect the signs of dullness, but at the first need to start the operation of sharpening the chainsaw chain. This will allow you to use it as long as possible.

Features of the structure of the chain

To effectively be able to sharpen a chainsaw chain, you need to know the structure of its teeth. You cannot do without knowing the sharpening angle. Each tooth has a complex structure. Its geometry is represented by the following components:

• the basis;
• scapula;
• depth gauge.

In this case, the blade consists of two blades: end and top. over, between them there must be the correct sharpening angle of the chainsaw chain in order to provide it with the necessary performance.

As you can guess now. the chain does not cut the tree, since it serves as the basis for securing the cutting links, moves them at high speed. The links themselves have sharp blades, with the help of which the wood is cut.

Helpful hints

Some helpful tips will help keep your equipment in good working order and also eliminate the risk of injury. Of course, it is necessary to know the correct sharpening angle of the Stihl chainsaw chain. But timely tire care is also important:

• The chain tension must be checked. Especially if the chainsaw tilts to one side during operation. Poor tension can be dangerous to humans.
• Sharpening in a timely manner, without putting everything on the back burner. It may be expensive, but it is better to give preference to electrical equipment.
• Lubricate the entire chain regularly, otherwise it may fly off (its speed is about 100 km / h). Everyone will draw conclusions himself.
• Do not use used automotive oil or any product of questionable quality. It is worth choosing only specialized lubricants. As the best remedy. autol.

Before starting to work with the chainsaw, the chain should be run in. Let it run at minimum speed for 40-50 seconds. Lubrication will reach every part, and the chains with a sprocket will heat up a little, rub against each other.

All these expert advice should not be ignored if you want to remain safe and sound.!

Features of the chainsaw

Sawing a tree is like working with a plane. In this case, the size of the cut depends on the thickness of the limiter. When the saw chain is used intensively, the teeth become dull more quickly. This is clearly manifested when the ground surface appears in the path of the chain. To completely blunt the teeth, it is enough to “catch” on the ground for a couple of seconds.

If you sharpen as often as possible, the chain will last much longer, since very little metal will be removed. In addition to the question of what angle of sharpening the chainsaw chain should be, this should also be known!

Working with a blunt tool is undesirable for a number of reasons. First of all, this is reflected in the quality of the cut, and not for the better. Also, fatigue quickly sets in, which is felt not only in the hands, but also in the body.

One more reason. unjustified excessive consumption of fuel. All parts will work in an enhanced mode, which inevitably leads to their rapid wear. Performance drops seriously, which also happens when using a defective chain.

Manual method

This is the simplest and slowest method for sharpening chain teeth. Nevertheless, the method is good when sharpening is done on site in the forest. Can’t carry a whole machine with you all the time ?! But here it is worth being more precise. not one instrument is meant, but a whole set, which includes:

• flat file;
• round file;
• template.

Each of them fulfills their duties. The main purpose of the flat tool is to sharpen the depth gauge.

The round file is already performing the main operation, making the cutting edges sharper. over, each chain requires a certain tool diameter:

• step ¼ inch. 4 mm;
• pitch 0.325. 4.8 mm;
• 3/8 inch pitch. 5.2 mm;
• pitch 0.404. 5.5 mm.

A 4mm file is also suitable for Picco chains on Stihl 180 chainsaws in 3/8 and quarter-inch pitches. It is important to hold it correctly. With respect to the vertical plane, the file must be placed strictly perpendicular to the chain, and with respect to the horizontal plane. at a slight angle (about 30 °). The specific sharpening angle is selected depending on the needs, but within the range of 25-35 °.

Unlike sharpening a chainsaw chain on a lathe, the angle can be set here using a template, which is considered a useful assistant. For this, it is equipped with two slots: SOFT / S (for softwood) and HARD / H (for hardwood). The template should be pinned over the chain, which gives it delimiter privileges.

It should only be borne in mind that this method is not intended for permanent use, but only serves as a dressing of the blades. Using the file too often will wear out the chain over time and the teeth will not sharpen evenly.

Modern method

Almost every layman is worried about the question, what is the angle of sharpening of the chainsaw chain on the machine? You won’t be able to constantly use a file, an angle grinder is difficult to use, and for beginners this procedure is completely dangerous. There is nothing you can do about it, you have to use machines that can be both mechanical and electrical.

You will have to work with a manual machine for a whole “eternity”, and you get pleasure from using an electric analogue. Today, there are a wide variety of models to choose from that provide

• correct sharpening angle;
• high level of work quality;
• high sharpening speed.

It is also worth noting that sharpening is carried out evenly in relation to all links. All you need is to plug the equipment into the network, set the required angle, enjoy the spectacle or do other things. But the most important thing is that it will not be difficult to determine the angle of sharpening of the Stihl chainsaw chain on the machine.

Although it is a long time to tinker with manual equipment. the process is very long, but it costs several times cheaper. In appearance, the machine resembles a bow saw, only instead of a blade there is a round file. The smallest tooth is also taken as a basis. In this case, two or three movements are enough for sharpening, after which you can move on to the next link. If necessary, process the limiter. change the file (round is replaced by flat).

What a saw chain looks like and when to start sharpening

The chainsaw chain has a rather complex structure: dozens of intricately shaped links create an ingenious plexus that can easily bite into the hardest wood species. How does this happen?

If you disassemble the chain into links, you can see that they on the tooth blade (2) have two cutting edges. a vertical side (4) and a horizontal upper (5).

Chip thickness and productivity depend on the depth gauge (3), which is also available on each perforated base (1). After each sharpening, the distance between the leading edge of the back of the tooth and the stop is reduced, so it must be processed as well. If the metal is grinded down to the marks, then further operation of the chain no longer makes sense. it will not fully function. It is necessary to make it a rule to check the sharpness of the cutting edges before starting work. The sooner they are sharpened, the less metal will have to be removed. This means that the life of the chain will be significantly extended. Finding out when it’s time to start sharpening is very simple:

• the chain stretches and sags, does not fit well on the saw blade;
• strong vibrations of the chainsaw body are felt;
• the load on the tool and the operator’s hands increases;
• when sawing wood, the shavings are very small, a lot of dust appears in it;
• decreases productivity;
• the shavings darken a lot.

If these signs appear, put off work immediately. The frequency of sharpening depends on the quality of the chain itself, the intensity of the load, the density and uniformity of the wood, the observance of the cutting technique and other factors. Before sharpening the chainsaw chain, prepare the necessary tools and a place.

A few secrets on how to sharpen a chainsaw chain. The complete guide

Chainsaws are not only tools for professional lumberjacks or builders, but also for owners of private land. With the help of low-power household units, you can quickly trim trees and shrubs, and make minor repairs. To solve complex problems (sawing wood, building a house, etc.), you need to purchase a tool with more serious characteristics. There are also professional-grade chainsaws that are able to work a full shift without interruption, but in everyday life their power is unlikely to find use.

And yet, any experienced user will tell you that the effectiveness of a tool is not at all determined by its power characteristics, but by the sharpness of the chain. If a small but serviceable unit is able to cope with the functions assigned to it, then it is better not to try to work with a blunt, even professional, saw at all. In this case, not only performance will suffer, but also the load on the engine, fuel consumption will significantly increase, and many parts will simply fail. You can put the instrument in order at any service center or workshop, but what if there are none nearby? Many DIYers know how to sharpen a chainsaw chain on their own. Of course, the work is not easy, but it can also be done quickly and efficiently if you apply special techniques.

Best Chainsaw Sharpener Ever. FINALLY!!!

How to sharpen a chainsaw chain with a file

Files are the simplest chain sharpener. A tool with a round working part is used to sharpen the inner surface of the tooth, since its outlines are as close as possible to the circle. A flat file is needed in order to process the cutting depth stop. You can, of course, choose the right kit from individual tools, but it’s still better to get a ready-made one right away. Kits are commercially available that are suitable for sharpening chains with a variety of performance characteristics.

Most often, the kit includes a round file for the cutting blades, a flat file for the depth gauge, and a template to help ensure the teeth are identical after sharpening. To make the process go quickly and correctly, you need to do the following:

• before you sharpen the chainsaw chain with a file, you need to apply the template so that the teeth are exactly in its slots;
• the blade of a round file is brought under the cutting edge, which is sharpened in several movements parallel to the lateral edges of the template;
• to ensure uniform grinding of each tooth, you need to make the same number of tool movements for each link, and only in one direction.

No less popular among home craftsmen is another set consisting of flat and round files, as well as a gauge template adapted for stitching a stop. It is also quite simple to use the kit at work. The round file is fixed in a holder. a metal plate engraved with straight lines. They are designed to determine the correct sharpening angle for your chainsaw chain. The work process is as follows:

• the file with the holder is placed on the tine, focusing on the corresponding mowing line. The plate should rest on the depth gauge and the top of the tooth. In this case, the file blade is located under the cutting edge;
• gauge gauge (slotted plate) is designed to control the height of the cutting depth gauge. The device is superimposed on the prong;
• that part of the cutting edge that protrudes from under the surface of the caliber is grinded.

If you are the owner of a high-quality professional chainsaw, then processing chains with such hand tools can only be done as a last resort. This is best done on professional equipment. If at a certain moment there is no access to it, then you need to at least follow these rules:

• the tire must be secured securely and accurately;
• files are selected strictly according to the diameter, and its fifth part should protrude above the cutting edge of the tooth;
• movements should be smooth and accurate, with equal pressure;
• the file must be rotated around the axis so that it grinds itself evenly;
• the teeth are sharpened consistently and in the same way. The first one should be noted so as not to go to the second round;
• first, the teeth are sharpened in one direction, and then go to the other;
• if the cutting edges protrude at different lengths, then you need to focus on the smaller one, and grind the rest under it.

Following these simple rules, you can quite successfully tweak the chain using hand tools. Even if you have a professional chainsaw, and there is no special equipment nearby, it is better to sharpen your teeth in such a way than to work with a blunt tool.

Types of tools used for sharpening saw chains

All the devices with which you can return the previous sharpness to the teeth of the chain are divided into two large categories:

• hand tools (flat and round files, holders with fishing lines, hooks for removing sawdust);
• machine tools (mechanical and electrical).

Hand tools are, of course, cheap and can be found in any DIY toolbox. But work with it is progressing not only slowly, but with strong grinding of the teeth, it will be quite difficult to give them the desired shape. If you use at least a manual machine, the process will be much faster. Before sharpening the chainsaw chain, you need to set the necessary parameters on the device, and to sharpen the teeth, it will be enough to make 2-3 movements. Electrical equipment allows you to further speed up the work, but buying it for home use is not always advisable due to the high cost.

Compliance with some rules will allow you to learn how to sharpen the chainsaw chain correctly, which will contribute to high-quality work and less tool wear. The manufacturer specifies a constant value between the height of the stop and the tip of the angle of the cutting edge of the tooth. The main condition for sharpening is to maintain these parameters. And therefore, in the process of work, you should not be too zealous, since not only the functionality of the chainsaw, but also the safety of the operator depends on the identity of the teeth. If sharpening is done incorrectly, then the engine will be subjected to severe stress, and the chain can simply break and injure others.

How to sharpen a chainsaw chain correctly on a machine

The machines have a rather complex structure, which allows you to sharpen chains quickly and efficiently. In this case, the teeth are the same length, which significantly increases the service life of the tool and its productivity. To achieve this result, the machine is adjusted to the cutting edge that has been ground off the most. Then the first tooth is sharpened, and on it already all the rest.

To get a working chain, you must follow these rules:

• the tool is installed in the machine so that the links are directed to the sharpening stone;
• the polarity and angle of sharpening are determined (by default it is 30˚, but there may be other parameters);
• you should not cut more metal than you should. this will significantly reduce the life of the chain;
• it is better to process the teeth after one. this will shorten the time and allow you to achieve greater accuracy;
• after sharpening, the chain must be blown out in order to get rid of metal filings, and then treat with oil.

This process can seem complicated and time consuming. But in fact, all the operations are quite simple to perform on your own. Watching a video on how to properly sharpen a chainsaw chain on a machine will allow you to get a general idea of ​​the work of the master.
