The frequency of sharpening chains of a chainsaw. How to sharpen a chain of a chainsaw: order of work, features

A good master and the tool should be good, and always be in combat readiness. This applies to any masterful person. All cutting and sawing devices should always be properly sharpened. This requirement is relevant for such complex tools as saws, especially to electric and gasoline. In today’s review, we will figure out how to sharpen a chain of chainsaws, what you need to know for this in order to make work efficiently.

Features of sharpening saw chains

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

Chainsaw

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

Tooth configuration and angle of sharpening of the chain of the chain

The tooth of the chainsaw has a complex configuration, which depends on the direction of the circuit. The tooth has two working edges: side, located perpendicular to the axis of the movement of the links, and the upper one, which is at a certain angle to the direction of the chain movement. Each tooth has a cut depth limiter. It determines the height of the shot chips. The main effort with the abroad falls on the working edge. The angle of sharpening of the tooth determines the quality of the tool.

Functional parts of the tooth of the chainsaw and their type

Important! Tooth configuration should be checked regularly, especially before a long.Term work.

Each saw model has its own step of cutting edges, the value of which for household and semi.Professional models is associated with the power of the unit and the torque. For longitudinal sawing, a step is taken less (for example, 0.325 inches). The performance of the work will decrease, but the required effort will also decrease. With a roll of trees with a large engine diameter, the engine power does not exceed 2500 watts. The thickness of the cutting edge in 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 the longitudinal saw should be very acute and have an angle in the range of 6º 12º, for the transverse. Up to 25º 30º.

In the first case, sharpening should be carried out more often, since the small angle of inclination of the tooth contributes to its rapid painting unacceptable. This is especially noticeable in links that are made of structural alloy steels containing silicon and manganese, for example, 40 HGS or 35HGS.

Templates and appliances for sharpening the chain of the chain

It is much easier to work, having great confidence to get the right result, if the master has provided himself with a set of auxiliary devices, which includes a template. With it, the correct values ​​of all angles of tooth sharpening are withstanded with it. The angle of the front edge is recorded in the instructions, usually its value is 65º. 80º. The assessment of the value of the rear angle of the upper blade can be performed only according to the template. Its value should be in the range from 50º to 60º.

The rear angle of sharpening of the saw decreases with an increase in the hardness of the wood. The optimal with a longitudinal cut is considered the value of the angle of 10º 12º, and 25º 30º. With a transverse cut.

The frequency of sharpening chains of a chainsaw

The decision to sharpen the saw chains is made not according to the calendar, but according to its work. First of all, the sawdust should be examined. If they look like fine dust, then the chain requires sharpening. Otherwise, you can overheat the engine, which will lead to the formation of bully on the cylinder. The stupid saw has increased vibration and the difficulty hiding of the headset into each new cut, which significantly reduces the performance of sawing work.

How to sharpen a chain of chainsaw at home with a file

Correctly sharpen the chain of chainsaws with a file will help a tool of exceptionally round section. The parameters of the file are determined by the size of the saw itself. It is important to know the step of the location. One round sharpener is not enough. For sharpening and editing chains, two types of tools are used. The first, this is a gun file with a diameter corresponding to the diameter of the rounding of the working edge of the saw tooth. To process the limiter of the saw depth of the guide tooth, you need a flat file.

Sharpowing can be performed manually using a round file with a working diameter of 4 5.5 mm. It is extremely important to correctly install the tool relative to the hidden tooth. The upper edge of the working part of the file is located approximately the fifth of the upper edge of the processed part. The tool is held perpendicular to the axis of the chain at an angle of 25º 30º to the upper edge of the tooth.

For sharpening saw chains of a household tool, round files with a diameter of 4 and 4.8 mm are used, since they have a small tooth. For professional models, more powerful chains with a large tooth are used. Therefore, you need files with a diameter of 5.2 and 5.5 mm.

To sharpen the limiter, a flat file will be required, and to clean the place of work. A hook that removes the formed sawdust. There are also special holders on sale, on which the files of the movement of the file of the file relative to the axis of the chain are sophisticated. The holding can be installed on the tooth on top, resting on its upper edge. Since its height is adapted to a certain step in the chain, this device should be selected in relation to the chainsaws of specific models and brands. The minimum necessary set in order to get the right angle of sharpening the circuit manually, shown in the photo.

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

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

  • Sharpen with the use of a file (the most common method of sharpening, t.To. Allows you to tighten the tool directly at the place of work on sawing.)
  • Silence using a special machine (this method is used in service centers, but can also be used in the personal economy)
  • Imprison with the use of corner grinders. To sharpen this method, it requires certain skills. A little.Won method, t.To. It is difficult to sharpen with the help of an angular grinder correctly.

1 method. File

The first thing you need in order to sharpen the chain, or correct it a little, these are special files.

File

For sharpening and editing chains for saws, two types of files are used. The first, this is a gun file with a diameter of the corresponding diameter of the rounding of the working edge of the saw tooth.

For sharpening saw chains of a household tool, 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 a large tooth are used, and accordingly, files with a diameter of 5.2, 5.5 mm are needed.

In order to properly sharpen, it is not enough to sharpen only the cutting edges of the tooth, you still need to adjust the restriction of the cut depth of the cut. If this is not done, the chain will not crash into the sawing material to the required depth, which will noticeably reduce the speed of work and in the same way as in the situation with a dumb chain can lead to a saw engine overheating due to a not enough load on the engine. This work is done using a flat file.

It is worth remembering that the use of a blunt chain can lead to overheating of the engine and the formation of bully on the cylinder.

Process description

The first where the editing of the saw chain begins on the saw is the installation of the tool on an even platform or table. In forest conditions, for this, a large.Diameter chock is well suited. Next, you need to examine the saw chain for any defects, it can be cracks, completely fragmented teeth. After inspection, you need to install the brake in working condition, thereby blocking its movement along the bus.

The chain during sharpening with a file should be stretched.

It is advisable to lay a stand under the tire, you can use logs as it, a piece of a branch of suitable diameter, or the manufacturers of sharpening tools have special clamps to hold the tire during the sharpening of the circuit.
sharpen, chain, sharpening, means

Stihl clamp

The circuit is sharpening is carried out by the movements of the file from the inside of the tooth outside. In this case, the file should be located parallel to a special mark on the chain. This label is applied by the manufacturer of circuits to specify the standard angle of sharpening.

sharpen, chain, sharpening, means

The hidden 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 advance the chain along the tire, without forgetting to install the brake in the working position each time.

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

sharpen, chain, sharpening, means

Ideally, manufacturers advise to conduct the same number of movements with a file for each tooth, but in practice this is not always possible, t.To. Teeth have a different degree of damage to the working edge.

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

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

Another device designed for sharpening is a manual machine for editing saw chains. As a sharpening tool, it uses a regular file that can independently replace. The machine is mounted directly onto the tire, it also has the ability to adjust the angle of tooth sharpening and a special emphasis that holds the pulled tooth.

Hand machine for sharpening, perfect for beginners. Along with electric models for sharpening, manual has its own undeniable plus in the form of a low price. Depending on the manufacturer of a manual machine, their appearance may vary, but everyone has one principle.

The cut depth adjustment is carried out using a flat file, so that there is a difference between the upper cutting edge of the tooth and a height limiter.

As can be seen from the figure, the depth limiter is flowed in such a way as to bring the clearance indicator to the factory value. Below is a table, which contains the main values ​​of the angles, as well as the clearance for the most common types of circuits.

As a rule, the size of the gap is adjusted using a special dick. It is installed on the circuit during sharpening, after which the depth limiter grows.

The use of corner grinders as a gaspecraft sharpener

You can sharpen a chain of chainsaw with an angular grinder, though in this case it will be necessary to show accuracy, since the use of this technique does not involve the use of limiters. Previously, the equipment is fixed on a workbench or table, for which it is better to make any clamp. After fixing the power tool, it is checked for the presence of vibrations. The fixed power tool is checked for the presence of vibrations, which are unacceptable when performing accurate actions. Sharpening technique consists in conducting links in an abrasive circle.

Attention! The tool shaft rotates at high speed and transfers the load to the circuit, which can be dangerous for the sharpener.

In addition, when using a corner grinder, there is also a risk of making several mistakes:

  • The thickness of the removed layer is not controlled;
  • There is a high probability in the assumption of errors when grinding the teeth;
  • There is a danger of cutting the connecting ears that fixing the link.

Fixing the corner grinder with a clamp or vise, the disk is placed in a vertical plane. The alternative method consists in fixing in the vice of a corner grinder, but saws, while the tool is brought to it.

Sharpening of the chain of the chain of the chainships with your own hands

Sharpening of the chain of the chainsaw is perhaps no more complicated than sharpening of the other cutting tool, but subject to special devices for sharpening it. Her tooth has complex geometry. Two cutting edges. Lateral and upper. Of which the second is mowed at a certain angle to the chain movement line, this operation is not easy.

Chain of the chainsaw

The tooth of the chain stricts the wood like a roof, and the thickness of the shavings is regulated by the height of the limiter.

Strict of wood tooth chainsaw

The intensive work of the saw leads to the rapid tag of the chain. Within one day, several sharpening may be required. Aggravates the problem that the tooth is quickly stupid when meeting with the soil. It is enough to hook the soil once or twice, and the work can be stopped. The chips become small, and the saw stops deepening into the tree.

The sooner the dull teeth are sharpened, the less material must be removed when sharpening, as a result. The service life of the saw chain is longer. Determine the moment when sharpening is already required is simple enough. An important feature is the supply effort. Correctly sharpened circuit is drawn into a cut already with a slight press. If, on the contrary, the chainsaws are forced to saw with increased effort effort, then the teeth are dull. A blurry chain can also be recognized if, instead of a large thick chip from cut, only small chips fly out.

Chips from the operation of a sharp and dumb chain

In this situation, the chainsaw should urgently hide. Do not saw a blunt or defective saw chain. The consequence is a strong tension in the body, a large cyclic load, poor cutting results. In addition, this means a decrease in performance, a high fuel consumption and increased wear of all the nodes of the chainsaw.

The parameters of the teeth of the chain

The cutting link consists of: link base (1), tooth blades (2), depth limiter (3). The tooth blades have a vertically located end blade (4) and the upper blade (5), located horizontally, falling at an angle back.

Parts of the cutting link

To achieve optimal cutting properties, certain angles are given to the tooth blades. The back of the tooth falling at an angle forms the rear angle of the upper blade. This angle is needed to cut the upper blade into wood.

The rear corner of the upper blade

A tinge taps taping back forms the rear angle of the end blade. This angle is needed for side cutting chips.

The rear corner of the end blade

The edge of the end blade forms the front angle with the surface of the cutting link sliding. The front angles in different types of chains vary from 60 to 85 °.

Front corner

The rear angle of the upper blade characterizes the tilt of the upper blade back.

The rear corner of the upper blade

This angle is measured relative to the sliding plane of the cutting link and, depending on the type of saw chain, has a value from 50 ° to 60 °. The upper blade is the main blade, and the rear corner of the upper blade. This is the most important angle. The rear angle of the upper blade is difficult to measure, its correct value is formed subject to other prescribed values.

The angle of sharpening or angle in the plan is obtained by measurement from the upper cutting edge at right angles to the guide tire.

Angle of sharpening (angle in plan)

The angle of sharpening can be changed, depending on the case of application. Basic rule: the larger the angle of sharpening, the higher the cutting performance during the cut of the non.Dashed soft wood. Reducing the angle of sharpening during the cut of frozen and/or solid wood contributes to the smooth progress of the saw and a decrease in vibration. However, the sharpening angle of more than 35 ° or less than 25 ° should be avoided (the exception is the circuits for the longitudinal sawing, in which this angle is 10 °).

The front angle, the angle of sharpening and the angle of the upper blade change when sharpening. These angles have a decisive effect on the cutting ability of the chain. Be sure to follow the prescribed values.

At each cutting link in front of the spatula of the tooth there is a depth limiter. The difference in height between the upper edge of the depth limiter and the front edge of the tooth back is defined as the distance of the depth limiter.

The distance of the depth limiter

The depth of cutting the upper blade into wood (chips thickness) and, thereby, performance, depends on the depth of the depth. The distance of the depth limiter is set depending on the chain step and the type of execution. Normally it should be 0.5-0.8 mm, more often 0.6 mm. High values ​​will lead to an increased tendency of the chainsaw to the return, too much capture and vibration of the chain. Low values ​​lead to a drop in performance. Since the distance of the depth limiter with each saw sharpening is reduced due to a decrease in the upper face of the tooth, the depth limiter also needs periodic file. After 5-10 sharpening the circuit.

Sharpening of the chain

To achieve the optimal result, we recommend using the sharpening templates for Husqvarna sharpening. Try to shoot as low as possible layer of metal.

Start sharpening from the shortest tooth. All teeth should be adjusted to the length of the shortest.

How to Sharpen a Chainsaw Chain with a DRILL.

  • Install the sharpening template on the circuit. The arrows on the template must correspond to the direction of rotation of the chain (to the driven star). Make sure the template fit tightly to the chain.
  • Use a round file. Place a file at an angle of 90 ° to the rocking template rollers. Sharpening, holding a file with two hands. The file should rely on both videos. The teeth should be treated with a file from itself with even stroking movements.
  • After processing one tooth, proceed to the next. Each tooth should be treated until the necessary severity is achieved. The length of all cutting teeth should remain the same.
  • After the sharpening of the teeth is completed on one side of the chain, weaken the vice and turn the guide tire. Sharpen the teeth in an identical way in the opposite direction.

Sharpening of the circuit with a corner grinder

If you have a corner grinder, then you can sharpen a chain of chainsaws much faster. It is best to use a small corner grinder with the 125th circle. Sharpowing is carried out at low speeds. There are two ways to sharpen an angular grinder.

The 1st method

Install the chainsaw on the table, and clamp the tire with a vice so that in the process it does not move. We put low speeds to the corner grinder (if there is only a smooth adjustment, then we slightly click on the start button). We direct the disk at an angle of 30 ° relative to the plane of the tooth and tilt slightly (as shown in the photo). Press with light soft movements on the tooth.

With this method, the main thing is not to overheat the tooth and not to hide too much metal. Dilling the teeth, thus tightening, is much easier than a manual file, but the sharpening speed increases significantly.

The 2nd method

In this case, it is motionless to fix exactly the angular grinder. Can be squeezed in a vice or screwed to the workbench with a bracket. Sharpowing is carried out, as on a normal toe circle. Hold the chain with our hands and turn it so that the tooth is sharpened at an angle of 30 °. With this method, the hands are less tired, since you need to hold the chain, and not the corner grinder. However, the chance to get an injury increases significantly. We recommend using this method infrequently or not to use at all, since safety is still more important than speed or sharpening quality.

Options for doing work

It is important to know how to sharpen a chain of chainsaw at home, so as not to delay the process of working with lumber and not break the tool. Sharpowing the electric saw chain with your own hands is no different from the editing of the cutting element of a saw with a gasoline engine

You can choose one of the available ways:

  • The editing of teeth using a file is the most common and easy way that allows you to sharpen directly at the place of work.
  • You can focus the teeth using the PowerSharp system.
  • Using a special sharpening machine. This method is used by service centers, but it can quite be used at home.
  • With the help of corner grinder (corner grinder). In this way, inexperienced users are unlikely to be able to use, as it is rarely used and requires certain skills.

STIHL chainsaw angle

It is important to withstand the angle of sharpening of the rear angle of the upper blade, you can only do this using the template. In other ways, this is extremely difficult to achieve, t

To. Its value ranges from 50 to 60 °. The angle of the front edge can be changed, depending on what type of sawing you will produce. The stronger the wood breed, the smaller the angle, otherwise the edge will bend. Optimal angle values ​​10 12 ° with longitudinal sawing, and 25 30 ° with the transverse method. Its performance depends on which angle of the edge is used in a particular case.

The editing of the chain with a file

Sharpening of chains of chainsaws is carried out by two types of files: round and flat. A round file should correspond to the diameter of the rounding of sawing teeth of a particular chain. For example, for sharpening the chainsaw of Stihl 180 with your own hands, you will need a file with a diameter of 4 mm. For other chains of this type, files can be used with a diameter of 3.8 to 4.8 mm. For circuits that are used on professional saws, we use sufilies with a diameter of 5.2 to 5.5 mm. Read about sharpening chains here.

For proper editing the chain of use only a round file is not enough, because, in addition to sharpening the teeth, it is necessary to adjust the limiter of the depth of the cut. If you miss this important point, then the chain will not be able to bite to the desired depth into the body of the sawing material, and this will significantly reduce the speed of the work and will affect the engine resource. For this type of sharpening, you must use a flat file.
