It is possible to significantly increase the overall life of the cutting tool by pre-working.
To do this, when using the tool for the first time, the feed is significantly reduced (about twice) and the edge is blunted.
It is known that the service life of the canvas depends on its use.
The canvas that has not been subjected to frequent shock loads and has been used for its intended purpose all the time will work as long as possible.
This observation is especially relevant for machines with one or more sections.
It is very important to choose the right feed rate.
It should change based on the processed material, its volume and the nature of the feed.
In particular, the beam must be fed close to each other with the ends facing each other.
Too strong a feed will certainly cause the web to shift towards the guide backrest, which, in turn, may lead to the destruction of the teeth.
Among other things, the durability of the canvas is influenced by two other factors: sliding on the surface and idling mode.
To better understand the essence of these concepts, it is necessary to accurately understand the definition.
So, sliding on the surface of the workpiece is a sawing process in which the blade is immersed in the workpiece only for some part of it.
When the canvas is used on a thin bar, then during operation it can jump out of the sawing channel and simply begin to slide along the surface of the wood.
If this happens, the most minor consequence will be a violation of the wiring of the canvas, but it may also be seriously damaged.
If the back of the guide rail and the canvas are in contact with each other for a long time, then the back may be damaged.
She will no longer be able to hold the canvas on the desired line, the saw will shift, and the workpiece will be spoiled.
If the workpiece is not sawn through to the end and for some reason the feed stops, then this is called idling.
At this moment, the teeth of the web do not cut the wood, but only rub against it.
This inevitably causes the entire canvas to heat up and there is a possibility of its rupture!
