The quality of the chainsaw is due to its proper operation, and most importantly, proper and timely care for the chain. The sharpness of the latter must always be at its best. Good chain sharpening is a guarantee of comfortable and safe use of a chainsaw. And the professionals say: a well-ground chainsaw chain is much more important than the performance of its engine.

Moments that indicate the urgency of taking measures to sharpen the chainsaw chain:
- saw rotation speed is low;
- the tool starts to drive in different directions;
- the characteristics of the chips change: dust appears in it, sawdust begins to resemble needles more.

There are no deadlines for sharpening the saw. Professionals every time a little undermining the tool before working with him. The chain becomes dull depending on the intensity of its use. It is enough to pay attention in the course of work to the characteristic signs of dulling.
Sharpening chainsaw chain is not difficult. This task can be done by anyone who has the skill of sharpening a cutting tool. Naturally, it will have to grind through special grinding tools.
The chain tooth is represented by a complex configuration and is equipped with two edges: on top (it has a bevel at a certain angle) and on the side. The chain device makes its own adjustments to the operation.
How to sharpen the chainsaw chain itself and what options for this are available, this will be discussed below.
File Chain Sharpening
The scheme of wood planing tooth chainsaw.
This method distinguishes the cost-effectiveness of the purchase of appropriate equipment, since such a device as a file can be found in the arsenal of any home craftsman.
The first step is to decide on the diameter of the file, which is selected according to the size of the cutter:
- for 1.3 mm you need a file with d 4 mm;
- for 1.6 mm you need a file with d 5.2 mm;
- remove the limiters from the incisors with a flat file.
When performing processing with a manual file, it is important to observe a certain angle on the cutting tooth. The maximum honing angle is indicated on each link tooth by a special factory notch. This angle should be maintained using a round fixture.
Forms of tooth chainsaws.
In addition to cutting teeth, each chain link is equipped with a limiter that determines the maximum amount of teeth penetration into the wood. Limiters are sharpened much less frequently than teeth. And only when the height of the cutting teeth decreases as sharpening, the full functioning of the chainsaw becomes difficult.
When sharpening a file with a file, special importance is given to such an auxiliary device as a clamp. Its main duties are to fix and fix the saw bar. A clamp is usually attached to the edge of a workbench or table. Reliably fixed equipment - the key to impeccable sharpening.
The pattern is another accessory that has rollers to move. It is strengthened on the saw blade. Having chosen the desired angle for work, it is marked by means of a piece. All subsequent process essence is reduced only to driving a file along the groove of this device. Thanks to the template, the risks of improper sharpening and other difficulties are minimized.
Advantages of the option: low cost and simplicity.
Disadvantages: requires the application of large forces and time expenses. The file for the next sharpening will have to purchase a new one.Back to table of contents
The scheme of the chainsaw device.
- machine manual action principle;
Not all chains can be well sharpened with a file. For example, when the cutting edge of a chain loses its shape, sharpening it will entail a lot of effort.
For such cases, an excellent option is to use the machine. Machines are divided into manual, powered by electricity, with a grinding stone or grinding wheels. This method allows to achieve greater accuracy in the work, although it is not new.
The preparation procedure is carried out as follows.
Step of the cutting element of the chainsaw chain.
The first step is to loosen the clamping adjustment screw. After that, the chain is set so that the grinding stone serves as a guideline for the direction of its links. Then set the desired angle for sharpening.
Sharpening is possible in two ways:
- Consistently. Teeth are processed alternately one after the other, with a change in polarity.
- Processing every 2nd cutter. Left side, then right side. It is possible on the contrary (at will). In this embodiment, the sharpening polarity does not change.
Rules for honing on manual machines:
- The optimal level of sharpening is determined by focusing on the most blunt tooth.
- You should not grind the chain deeply, as this will reduce the strength of the link and the period of operation of the tool.
- Directly after sharpening, it is recommended to blow the chain with compressed air, and then - to put in the oil for two hours.
Advantages of the option: sharpening accuracy. Cons: the process is time consuming and time consuming.
- automatic machine;
The main parameters of the chainsaw chain.
Automatic sharpening of chains on special machines is very much in demand in practice. Machines more often find their use in woodworking institutions and sawmill workshops, often at home.
The machine is represented by a compact "box", within which the grinding stone is located. The saw is installed in the box, fixed and closed.
Then, set the maximum power on the chainsaw and turn it on. A chain in motion is sharpened on a stone inside.
Advantages of sharpening: the process is very short and elementary, does not imply that the saw host has any special skills and efforts.
Minuses: additional purchase of chains, produced by the same manufacturer, from which the device itself was purchased, is also required.Back to table of contents
Grinding the incisors with a grinder
Someone considers this option "barbaric", as if it harms the chainsaw. In fact, this is not the case. The method is quite popular and the most difficult to perform. The likelihood that an inexperienced person could harm an instrument is still there.
If sharpening this method has never been done independently, it is better to choose another way.
The chain is not removed from the tool. Apply already been in operation (with rounded edges) disk (2.5 mm) on the metal.
The sharpening angle is picked up by eye. It is recommended to install a wooden wedge between the side of the tire at the bottom and the chain.
Advantages: long service life of the equipment after sharpening (4-7 sharpening); low cost, spent little time and effort.
Disadvantages: requires mandatory measures to protect hands (mittens) and face (face shield), which will help to avoid injury in the process of sharpening and make the process much more pleasant. For those who do not have enough experience working as a grinder and cannot sharpen the teeth with the necessary precision, it is better not to consider this option.
Choose the most appropriate method of sharpening - and go ahead. Good luck!
