Chainsaw chain sharpening machine: a reliable assistant to a home craftsman
A chainsaw is a necessary item in the arsenal of the owner of a suburban area and a home craftsman. During operation, the working part of the tool wears out greatly. To restore its cutting properties, you will need a machine for sharpening chainsaws. This equipment is presented in a wide variety of species. To choose a good tool correctly, you should study its technical characteristics and familiarize yourself with the types of devices.
How to use a Chainsaw Chain Sharpening machine
During operation, any chainsaw wears out the working part in the form of cutting teeth. With a little wear, they can be corrected with a round file. The chainsaw chain must be sharpened on the machine if, when cutting wood, it is necessary to apply great efforts, with the formation of small sawdust instead of large brittle straws, the appearance of a burn on wood or sawdust, the detection of incorrect operation of the device, which can jump, move back or to the side.
The grinding machine is represented by a design that is similar in appearance to an assembly cutting machine. Only here a grinding wheel is used instead of a cutting disc. To sharpen the chain, it is customary to use a whetstone with a thickness of 3.5-4 mm. It is fixed on a frame with a hanging head and clamped with special fastening vises.
Before performing the process of sharpening the chainsaw links, the machine is pre-configured with a choice of the angle between the chain and the grinding wheel, which is determined by the pitch of the teeth. Sharpening chainsaws with your own hands consists in forming the end and side blades and ensuring the correct gap between the front of the cutting link and the plane of the depth limiter. Special risks are applied to the surface of the teeth to determine the required sharpening angle, on the basis of which the parameters for the operation of the machine are set.
Important! Before using the machine for sharpening the saw, you should read the operating instructions, which contain important recommendations for setting up and using the equipment.
With the help of rotary clamps, the working part of the chainsaw is fixed on the machine. The abrasive disc rotates and is consistently brought to each link of the unit. The grinding machine allows not only to sharpen the teeth, but also to straighten the chain links.
Chainsaw chain sharpening machines can be manual, semi-automatic and automatic.
What is a manual chainsaw chain sharpening machine
The manual machine for sharpening chains is represented by a small mechanical device that is attached to the saw tire. Such a frame with a file of the required diameter is characterized by several adjustment options for choosing the sharpening angle. The operator performs reciprocating movements, precisely maintaining the specified parameter for sharpening the links.
The manual chainsaw sharpening machine can be used in places where there is no access to electricity. It is characterized by versatility, low weight, compact size, autonomy, lack of risk when performing work due to overheating of the metal, low cost. In addition, the mechanical machine grinds the edge of the link minimally, which significantly increases the service life of the chainsaw.
Among the disadvantages, the inaccuracy of the sharpening angle can be distinguished. In addition, when performing work, the operator must account for the number of working passes of the file, which is important for uniform grinding of the teeth. Otherwise, due to the different sizes of the teeth, the quality of the chainsaw chain will deteriorate.
Important! Manual machines are not used for sharpening chains equipped with carbide dusty links.
Performing chain sharpening with manual equipment requires certain skills and dexterity. Here you should rely on intuition and the eye. During the work, it is required to cool the chain with compressed air, and at the end it must be immersed in engine oil.
Chainsaw chain sharpening on semi-automatic machines
Machines equipped with an electric drive are very popular (this is due to the high productivity and quality of sharpening). The equipment is a complex structure that consists of several elements. The base of the device for sharpening the chainsaw chain is the frame on which the engine and the vise with the slide guides for the chain are installed. The motor is used asynchronous type with direct transmission and high speed.
The grinding disc is mounted on the motor shaft and is fixed with a washer and nut. The area where the motor is attached to the frame is movable, which makes it possible to adjust the motor in space for the need to set the correct sharpening angle.
To install the chain and hold it, a vise with a slide is used. A limiting plate is fixed to them, which controls the depth of cut. When the adjusting screw rotates clockwise, the disc slides out, increasing the sharpening depth.
Semi-automatic sharpening machine for sharpening circular saws is characterized by the ability to set the exact angle of sharpening, align the working tooth. The equipment can operate from a 220 V and 12 V mains, which allows you to connect it using a car battery.
The principle of operation of a semi-automatic machine for sharpening saws
The principle of operation of the grinding machine for the chain is as follows. A chain is installed in the slide guides. The limiter is lowered until it reaches the stop in the back wall of the tooth, which is sharpened, not allowing it to move. Next, the engine is lowered with an abrasive disc mounted on it. When it comes into contact with the teeth, the edge of the cutting element is worn off.
After one side is processed, the chain is turned over to the other, the manipulation is repeated. Next, the operator must move the chain to the next tooth with the installation of a thrust bar, after which the process resumes.
Important! To sharpen the chain on an electric machine, it is important to set the grinding depth correctly so that the teeth do not overheat and lose their properties during operation, which will negatively affect the further operation of the saw.
The disadvantages of electric machines for sharpening chainsaws include their high cost, which starts from 6 thousand rubles., the need for periodic replacement of mounting wheels, which is also a very costly event. Diamond variants should be used to extend the life of the disks. However, they have a higher cost.
Distinctive features of automatic chain sharpening machines
The chainsaw chain is sharpened on a fully automatic machine without direct human involvement. This type of equipment has a completely professional purpose and is used at large logging enterprises. It is advisable to use it in repair shops, for which large volumes of grinding work are inherent. The machine for sharpening circular saws with carbide soldering is presented only in automatic execution.
The chainsaw chain is installed on the machine manually. Next, you configure certain parameters and start the device to work. The working bodies are moved by means of hydraulic drives, which are controlled by the controller. The chain is sharpened by two heads at the same time. The upper element is used for the cutting tooth, and the lower one serves as a depth-of-cut limiter.
Important! The chain is sharpened on both sides in one pass due to the fact that the upper head rotates in both directions.
Automatic chainsaw chain sharpening machines are characterized by versatility, reliability, durability, high quality and speed of operation, and an increased level of safety. The main disadvantage is the high cost of such equipment, which is unjustified for private use. Such professional chainsaw sharpening machines also provide standard fine-tuning of each saw link without taking into account the degree of wear of the element according to a single template, which can negatively affect the period of further operation of the working part of the saw.
Important! The automated process of chainsaw chain sharpening reduces the working life of the equipment by 15-20%.
How to choose a chainsaw sharpening machine: important recommendations
To decide which machine to choose for sharpening chainsaw chains, you should first consider the main indicators of the equipment. First of all, it is necessary to specify the diameter, thickness and speed of rotation of the disk for sharpening. The last indicator indicates the performance of the device and the rate of removal of metal from the cutting surface of the tooth. The optimal value is 30-35 m/s. This parameter is not specified by the manufacturer, but it can be calculated mathematically by knowing the rotation frequency of the disk and its diameter.
The next important criterion is the power of the machine. This indicator should be in the range of 85-180 watts, which is quite enough. This is due to the fact that the disc is in contact with the metal tooth for several seconds, so the equipment does not need high power for a high-quality sharpening process.
Useful advice! If the machine model has a power of 400 watts or more, this parameter is redundant. In this case, this device is recommended to be used for sharpening knives and any locksmith tool.
When choosing a device for sharpening chainsaw chains, you should pay attention to the equipment configuration. In addition to the machine, the structure may include a set of abrasive discs of various thicknesses, templates, test gauges and other keys.
Important! The machine must necessarily have a protective screen, which is the main safety requirement.
It is necessary that the machine be equipped with mechanisms that facilitate and accelerate the sharpening process, in the form of a chain tensioner, a synchronizer for automatically locking teeth when lowering the sharpening disc, a chain movement mechanism and a device for clamping it. The machine can be fixed to the horizontal part of the workbench or to a vertical wall.
When choosing a machine, it is necessary to check the mounting location of the engine and the guide for the absence of backlash. Their presence is evidence of poor-quality equipment that is unable to perfectly withstand the sharpening angle of the chain.
How to sharpen a chainsaw chain at home: useful tips
Before you start sharpening the chain on the machine, you should study in detail the technological instructions for working with the tool. On the chainsaw, loosen the clamping screw and remove the chain. Next, the saw element is installed at a certain angle on the seat, which is located on the base. Chainsaw chain links should be facing towards the circle.
The sharpening angle can be within 0-30 degrees. The device should be fixed in an immovable position by means of a clamp adjustment screw. The angle is selected individually for each product. For this purpose, a special scale and a rotary design element are used. The choice is made by the smallest prong. First of all, it is he who is sharpened. Then, according to the set settings, the rest of the links are processed.
Then it is necessary to precisely align the grinding disc with the edge of the teeth. The machine is put into operation, and the chain is sharpened. The process is performed sequentially for each element of the working cutting part of the chainsaw or through one tooth. The second option is faster and more convenient. After the end of the process, the machine must be disconnected from the power supply and loosen the chain tension adjustment screw.
