To ensure the smooth operation of band saws for a long time, it is necessary to run-in new saws.
The edges of the new ribbon web are quite sharp.
Therefore, if the saw is put into operation without running in, small irregularities may appear on the teeth, which shorten the service life of the blade.
During the running-in of the band saw, microradiuses are formed on the teeth, which protect it from premature aging.
Running-in, carried out in strict accordance with the rules, is able to increase the service life of the saw and give it the opportunity to develop its maximum resource.
How to increase the life of the saw There are a number of rules that help to increase the life of the saw:
- Do not sharpen the saw immediately after removing it from the machine.
- After work, the canvas should be turned out and hung.
- It is necessary to ensure that the factory geometry of the teeth does not change during the sharpening process.
- It is necessary to strictly observe the time mode of operation of the machine recommended by the manufacturer.
- The canvas must always be clean.
The presence of dirt on it can cause the canvas to slip or break.
- It is necessary to control the tension of the web.
Too weak a tension can cause it to slip off the pulleys, too strong – to rupture.
- Only certified equipment from trusted manufacturers should be used in production.
Wiring must be carried out regularly and in compliance with all rules.
If it is not there, you can use ordinary pliers.
The saw should be clamped upwards with the teeth.
During the wiring operation, the process along the web should be observed.
Then every other tooth is bent in different directions.
With each movement, the pliers should be tilted at an equal angle.
Often there is a wiring initially, but to a small extent.
Therefore, in most cases, you only need to increase it if necessary.
Such a need arises, for example, if you need to process raw wood.
The optimal divorce is when there is a mixture of 30-35% air and 65-70% sawdust between the tree and the saw.
Externally, the correct divorce characterizes the release of about 85% of sawdust from the cut.
If the saw is diluted too much, the sawdust is not removed well enough and too much air remains.
In this case, she will cut in jerks.
If the saw is not diluted, hot densely compressed sawdust will remain on the surfaces of the board.
In this case, she will cut in waves.
