The chainsaw is an indispensable tool for wood processing. It is used for sawing trunks, pruning trees and shrubs. Intensive operation of the saw part of the tool leads to its wear. To restore the tool to work, need sharpening chainsaws. The most convenient tool for this is the chainsaw sharpening machine. Its use allows you to extend the term tool life, improve work performance, save time and effort. To understand how to properly use the machines for grinding the cutting edge, you should be familiar with their types and principle of operation.

Chainsaw sharpening machine: the basic principle of the device

The machine for sharpening chains for a chainsaw, by its design, resembles an assembly cutting saw, in which a grinding wheel is installed instead of a cutting disc. This disk fastens on a machine basis - a frame with fixing clips and a suspended head.

The saw part is fixed on the support frame by means of a rotary vice, and the grinding wheel is alternately fed to each tooth. The angle between the chain and the plane of the disk is set depending on its pitch. A grinding wheel 3.5 mm thick is usually used to grind links.

The unit is securely fastened to the desktop, which guarantees safety and ease of operation.

Important! The disk should be located perpendicular to the chain, this makes each link as sharp as possible. Thorough editing of the smallest inaccuracies of each tooth separately will prolong its life to the maximum.

Most chain saw chainsaws are small, economical, productive and easy to operate.

The main types of machines for sharpening chainsaws

According to the functionality, all types of grinding machines for chainsaws are conventionally divided into professional and amateur, and according to the degree of automation, automatic (electric) and manual ones.

Automatic machine tools

Automatic devices for sharpening chains for chainsaws are used in workshops and service centers with a large amount of work. The unit is stationary, requires a large working space and has a high precision processing.

The advantage of automatic machines is wide functionality, which increases their working efficiency. Among the advantages of such devices is the ability to adjust the desired angle of the chain. Automatic devices have the following parameters:

  • weight;
  • noise level;
  • electric motor power;
  • spindle speed.

The greatest advantage of power tools for sharpening chainsaw chains is in its full process automation. Human intervention is only to install and turn on the equipment.

In order to work better, you need to know how to sharpen a chain of chainsaws with your own hands correctly.

The disadvantage of this equipment is the frequent replacement of the chain due to its rapid wear. The saw component is usually changed after several sharpening.

Manual chainsaw sharpening machines

Hand-held machines for sharpening chainsaw chains allow you to perform the work of sharpening a tool as accurately as possible. They are divided into two types: mobile and stationary. Possess the following technical parameters:

  • weight;
  • noise level.
The indisputable advantage of hand-held equipment is the maximum attainment of the quality of sharpening, low cost, operational safety and no need to connect to a power source.

Did you know? The name of the chainsaw "Friendship" was given in honor of the 300th anniversary of the reunification of Russia and Ukraine in 1954.

The disadvantages of the machine for manual sharpening the chainsaw chain include the laboriousness of the process, the need to acquire skills to work with it, and the high amount of time spent on the process. To use manual units, you must be able to determine the optimum angle, as well as the degree of sharpening of the saw and have the skill of blowing the links with compressed air.

Having experience with such equipment, it is possible to achieve very high-quality sharpening of the saw edge.

Important! When buying a machine for manual sharpening, please note that the files may not be included in its package.File size depends on the type of chain.

How to choose the right machine for sharpening chainsaw chains, selection criteria

One of the criteria for choosing the right chain sharpening machine is its cost. However, the most important indicator when choosing a tool are its main technical characteristics, such as:

  • spindle speed;
  • diameter grinding wheel;
  • power apparatus;
  • equipment.

Did you know? The first prototype of the chainsaw was manufactured in 1918 in the USA (California) based on a marine engine.

Spindle speed

The speed of processing of the spindle shaft depends on the speed. The optimum speed range is quite large - from 3000 to 7500 revolutions per minute.

As a rule, it is recommended to choose the minimum allowable rotation speed when purchasing a sharpening machine for the house. But with large volumes or daily use of equipment it is necessary to stop at a faster unit.

Grinding wheel diameter

The choice of the diameter of the circle also depends on the industry of application of the grinding tool. A disk diameter of 400 mm usually finds application in machine-building enterprises.Effective use of the unit with a grinding wheel diameter of 110 mm is possible, for example, in small workshops or in everyday life.

For people who care about their site, you need to know more about the equipment that serves them, for example, what is the best trimmer on gasoline to use, how to use the tiller or what is an adapter for the tiller.

Machine power

The sharpening machine is considered a tool with low power, not exceeding 220 watts. Engine power affects the life of the unit, its efficiency, and, of course, on what kind of sharpening machine to choose for home and which for a large enterprise. For domestic needs, the power may not exceed 200 W, for professional use - from 500 W. With frequent use of equipment, its power should be as high as possible.

Completion and additional features

The presence of any additional option when choosing a sharpening machine for sharpening the chain improves the quality of cutting edge processing, increases the speed of grinding and the service life of the unit. Additional features may include:

  • rotation of the grinding head and jig;
  • wet grinding;
  • spark protection screen;
  • protective covers;
  • tension adjustment;
  • cooling system;
  • automatic clamping vise and so on.
The wider the tooling, the higher the cost, respectively.

Did you know? The first one-handed chainsaw was released by Stihl in 1950.

What choice of machine for sharpening chainsaws is better, everyone decides individually, depending on needs.

Features of operation of the machine for sharpening chains

The essence of the procedure is to:

  • loosen the screw that holds the chain clamp;
  • arrange the links towards the sharpening stone;
  • set the required sharpening angle;
  • to grind.
However, there are certain features when grinding teeth, directly related to the choice of device.

Automatic Chain Sharpening Machine

To use an automated unit, you just need to place a saw in it, securely fasten and close. Next, set the desired power, adjust the depth and turn on the start button. Grinding is done with an abrasive wheel.

Work on the automatic unit takes no more than two minutes.

Manual machine

Sharpening the tape with a manual machine is made through the tooth, that is, the right-sided teeth are processed first, then the left-hand ones.

Important! The best way to carry out the processing of cutting teeth with a manual machine for sharpening chainsaw chains is to take the worn out tooth as a template and adjust the remaining elements to its size. This will allow you to evenly distribute the load on the entire working surface of the saw during its operation and will prevent breaks in the weak links.

Greater sharpening depth will reduce the strength of the teeth and reduce the life of the saw.

After sharpening, the tool must be cleaned with compressed air and lubricated.

Using the manual method of grinding, you can achieve high accuracy of work, but you have to spend a lot of time and effort for this.

Given certain knowledge, skills and availability of tools, you can make a choice in favor of an automatic or manual grinding machine.Only in a timely manner by sharpening the tool, you can keep the chainsaw in working condition for a long time.
