If the belt is operated incorrectly and the coolant is not used, its service life is drastically reduced.
In each situation, it is necessary to clearly know what conditions are optimal for the operation of the belt web.
The running-in of the web begins with a reduced feed rate and sawing power.
First, you should set the values to 70% power and 50% speed.
After a while, the speed and power can be gradually increased.
But, having felt the vibration, you need to gradually reduce the speed, until the vibration stops or stops completely.
It is very important to thoroughly lubricate and cool the canvas using lubricants and coolants.
In addition, when sawing some metals and alloys, it helps to get rid of chips.
The right approach to cooling the canvas is the key to its suitability for a long time.
During the sawing process, it is very important to monitor the condition of the chips.
If the chips are too large and have a blue tint, the canvas is overloaded.
If the chips are small, pulverized, it is necessary to increase the speed.
If the chips have the shape of small curls, then this signals ideal sawing conditions.
Careful care of the canvas is necessary.
You can start to observe how the teeth are being painted.
The reasons for this may be: incorrect (too small or large) the pitch of the web, poor fixation of the workpieces, too low speed or high feed pressure, leading to too deep embedding of the web into the material.
All of the above problems can lead to the destruction of the teeth of the web.
In addition, in case of improper operation, premature blunting of the canvas may occur.
The reason for blunting may be the choice of too high a speed for a particular material, the choice of an incorrect saw pitch, defects in the side guides or the installation of the saw is not perpendicular to the direction of material supply.
