absolutely all owners saws faced sooner or later with the need to sharpen the chain.This problem can be solved in two ways - to give the chain to the studio or perform their own hands sharpening chain saws.With the first solution is clear, but sometimes the service call is not possible - for example, the chain is worn when working in the country from which hundreds of kilometers to the nearest shop.In this case, will have to cope on their own.Let's talk, how to sharpen a chain with chain saws.

Need for sharpening saws
procedure for sharpening the chainchainsaw - no more difficult than any process of sharpening the cutting tool in the presence of special tools.Tooth chain saw has a complex geometry.Side and upper cutting edges, the second of which is tapered towards the line of motion of t
heavily on high performance chainsaw affects the proper use of its circuit, which should be a mandatory pre-acute and sharpened.The only way to ensure efficient and safe operation during its implementation.After properly sharpened chain saws important powerful engine.Turning saws must be done after its bluntness that is slow work, as the unit leads to the side.
Intensive work provokes rapid blunting chainsaw chain.Sometimes during the day may require a few cheats.Adding to the problem and the fact that the teeth quickly tupyatsya at a meeting with the ground.Even if you are one-half hook ground bus, you can stop the job - the chips will be fine, and drank stop to go into the wood.The earlier Blunt sharpened teeth, the less material you need to shoot at sharpening as a consequence - the time of useful life of the saw chain becomes longer.When
need sharpening saws
Unfortunately, sharpening chain saws in many cases is carried out of time - users simply do not notice the signs that indicate that there was blunt chain.Do not cut defective or blunt chain saw, resulting in poor cutting results, a large cyclic loading, high fuel consumption, the drive sprocket and the destruction of the tire.This in turn leads to a decrease in productivity, increased wear of all nodes chainsaw and falling useful life of the chainsaw.
In order to avoid such problems, pay attention while working on the type of chip.As chips will determine when you need to sharpen the chain.If it becomes darker than before, this is a clear sign that the chain requires sharpening.Blunt chain you can recognize if flies instead of cutting large colon only small chips.The chips at the same time there is a lot of dust, and it looks like a needle.
Simply determine when needed sharpening.An important feature of the feeding force acts.The goal, sharpened correctly drawn in cut even for small presses.If on the contrary, chainsaw Sawing forced to increase efforts to feed the blunt teeth.
Look close to the teeth of the chain - blunting in many cases can be seen with the naked eye.The need for sharpening chain saws calm you can determine at a reduced performance level - more difficult to cut, and the work takes the user more time.
cutting with chain saws chain link consists of the blade tooth base level and depth stop.The blade has an end blade of cloves, which are vertically arranged, and smooth upper blade, placed horizontally.
To achieve optimum cutting properties, you must make certain the blades of the tooth angles.The back of the tooth, which falls at an angle back, forms an angle of the upper blade, which is required for cutting into the wood of the upper blade.Shovel tooth that tapers back, forms an angle socket blade required for lateral cutting chips flying from the chainsaw.
edge of the end of the blade units with the sliding surface forms a rake angle that varies between different chains of 60 to 85 degrees.The slope of the back of the upper blade is measured in accordance with the slip plane level and depending on the species chain and up to 50 - 60 degrees.Top blade - the main blade and the angle of the upper blade - the most important corner.The angle of the upper blade measurement lends itself with difficulty, it is possible to correct the value if all the variables mentioned above.
you can angle sharpening chain saws to change depending on the application.The main rule: the greater the angle of sharpening, especially when cutting soft wood cutting performance nepromerzloy above.When cutting hard and frozen wood decrease sharpening angle reduces vibration and smooth course of the saw.But remember that the sharpening angle should not be greater than 35 and less than 25 degrees.Exceptions are chains designed for longitudinal cutting, the angle at which equals 10 °.
angle of the upper blade sharpening angle and cutting angle change when sharpening.These criteria have a decisive influence on the cutting ability of the chain.Before shovel tooth on each link is the depth.The difference in height between the edge of the back edge of cloves and the depth gauge distance is defined as the depth stop.
From this index depends on the level of insertion into the timber of the upper blade (chip thickness) and therefore performance.Set the depth gauge distance regardless of the type of performance and the chain pitch.It should be normally 0.5-0.8 mm, more often - 0.6 millimeters.
High values cause increased susceptibility chainsaws to impact, vibration chain and capture too much.Low values provoked drop in performance.Since each sharpening chainsaw depth gauge falls away from the upper face of the decrease cloves, depth also requires periodic filing - ten cheats.
General rules sharpening
Proper sharpening chain saws needs to comply with several recommendations.Before sharpening the chain is strongly recommended to pay attention to them.The acuteness of the angle of the cutting unit and the cutting height limiter must meet the criteria established by the manufacturer.Furthermore, it is important to have identical dimensions of all links in a chain.Otherwise, the performance may be reduced and the level of vibration and load on the engine - longer.Because of the uneven loads increases the likelihood of breaking the circuit.
Since the inner loop cloves in shape close to a circle, and the material is soft enough chain, the chain decided to sharpen the round file, which has a small diameter.Sharpening the saw needs accurate positioning with respect to a file sharpened cloves.
upper edge of a file should protrude above the upper edge of the pick about 1/5 the diameter of the file.Just before sharpening the chain with chain saws is recommended to know its parameters, it is recommended to choose a file, regardless of the diameter of the chain pitch.It varies typically in the range of 4-5.5 mm.The video
sharpening chain saws can be seen that file should be placed at right angles in the vertical plane and to the circuit 10 or 30 degrees - in the horizontal.All these conditions are met by only one of a file - is difficult, so you can use for sharpening chainsaw different devices, allowing to provide the required parameters of sharpening.They represent a set of which are included with chain saws to, or purchased at any hardware store yourself.
Devices for sharpening
A common kit for sharpening the chain with chain saws, includes round file, which is mounted in a special holder, Files flat, which is required for grinding the depth gauge that provides the latest operation pattern for sharpening chain saws, and special hooksto clean sawdust from the chainsaw.
on a file holder with round have lines that allow you to position it correctly with respect to the chain.The toolholder is mounted on the sharpened tooth respectively with lines orientation.The plate thus relies on the depth and the upper edge of the pick, and the file is located under the cutting edge.
Application holder ensures the correct height to fit a file to the tooth.There are different steps for different holder chain.The right choice of the holder, respectively, correct diameter of a file ensures that the latter will perform at 1/5 of the diameter of the back teeth.Use only need specific files.
before hand sharpening chain saws is necessary to fix the tire.Files are selected according to the type chain, the main criterion for selection in this case is its step.Round file has a diameter of 3 - 6 mm and are designed for sharpening cutting bits.In a flat file width varies from 4 - 12 mm, they are used for the removal of the reference cloves.
Pay attention to these recommendations, which help to correctly sharpen the chain with chain saws:
- sharpening should be done in such a way that 1/5 of a file for sharpening chain saws made on the cutting edge;
- instrument should not move back and forth, and in the same direction;
- every 2-3 sharpening tooth is to undermine the limiter cuts.
sharpening is performed in such a way:
- pre-set the brake circuit, tightly pinching the saw between his knees;
- then put the template in such a way that the "arrows" pointed to "nose" of the tire.Do not forget to mark the tooth chalk, which began with sharpening;
- move the file to the side, which is indicated by the arrows, the movement "from themselves" and do the grind;
- with a file of flat plates must be removed and the control tooth.In this case, the direction of movement can be anything.
It should be noted that working with a set of sharpening the saw chain requires certain skills, which is why no experience is not desirable to make an expensive sharpening chain.
No need to try too hard to press the file, do hasteless and smooth movements.Regularly turn the file to avoid one-sided wear.In a similar way to grind all the other teeth.It is more convenient to sharpen the teeth first one direction, then the same is done with the teeth of another direction, changing position.
When sharpening make the same number of movements a file on each tooth at the same pressure.Thus, it is the same length of teeth.The length of the cutting teeth should be equal.Different length of the teeth causes of uneven progress in the formation of the chain and it cracks.In the case of unequal length teeth need opilio all cutters on the length of the shortest cloves.
Sharpen a file can not all chain.If the power saw thoroughly plowed gravel or sandy soil, or it is not sharpened for too long, that the cutting edge has lost form completely, sharpened with a file would require too much time and effort.It is reasonable in such cases should be used the machine for sharpening the saw chain.These machines are divided into power that are equipped with dressing wheel, and hand tools.
working part of such devices for sharpening the saw chain resembles structurally luchkovye saw in which the saw blade is inserted in place of the long round file.Machines and sharpen the chain rule, driving under the one-size-length of the top edge of the teeth at the lower tooth is taken as reference.The complex mechanism of setting will help to put all the necessary parameters.
Sharpening should be performed 2-3 movements, beginning to after that for the next tooth and leaving all settings for the control cloves.This can provide the same procedure parameters sharpening absolutely for all teeth.When you grind limiter round file to change the flat.
Tools for sharpening chain saws - a simple and convenient to use.It is equipped with a system configuration that helps to establish a chain at the desired angle and precisely sharpened edge to fail to drive.There are machines that implement is lowered to the chain drive automatic clamping vise.
machine, in fact, performs a similar role as the circles for sharpening chain saws and caliber, but with greater accuracy.Sharpening is performed as follows:
- Loosen the screw to start that regulates clamping circuit.
- Set the chain guide groove in such a way that the units looked toward the grinding stone.
- Then set the desired angle of sharpening.The default value is an acute angle 300, but other options are possible depending on the scope of use of the chain.Polarity is selected depending on the sharpening tool - left-hand or right-hand.
- Spend sharpening.There are two options.The first of them - a consistent sharpening, shaping cutters, one by one, but every time in this case will have to change the polarity.Another is sharpening every other tool: first, the left-side processing, and then right-cutters, or, as you prefer.By reducing the number of operations, so there is no need to change every time the polarity is increased speed.
In the process, it is important to comply with certain rules.Firstly, the optimum grinding level determined from the length of the most blunt tooth, which serves as a reference.Secondly, it is desirable to grind not too deep because it leads to lower strength level.After the operation it is recommended to blow compressed air circuit and leave it in a clean oil at a certain time.
Now you know that such a procedure is like sharpening the saw chain with their hands, and what price sharpening chain saws.- Not an easy one, has its own characteristics and nuances, requires a minimum of basic skills, but it is solved at home.It remains only to choose one of the scenarios - the use of a file or manual machine.
