Use of cold cutting saw blade:

1. If the saw blade is not used immediately, it should be placed flat or suspended by the inner hole. Other articles or feet should not be piled on the flat saw blade.

2. When the saw blade is no longer sharp and the cutting surface is rough, it must be repaired and sharpened in time. Grinding can not change the original Angle, and destroy the dynamic balance.

3. Cold cutting saw blade inner diameter correction, positioning hole processing, etc., must be carried out by the factory. If the processing is poor, it will affect the use effect of the product, and it may be dangerous. In principle, the reaming should not exceed the original aperture of 20mm, so as not to affect the balance of stress.

4. Selection of alloy grinding wheel.

The bond strength of resin bond diamond wheel is weak, so the self-sharpening performance in grinding is good enough, not easy to block, high grinding efficiency, little grinding force, low grinding temperature, the disadvantages are poor wear resistance, high wear loss, not suitable for heavy load grinding.

The abrasive resistance and bonding ability of the ceramic bond diamond wheel are better than that of the resin bond. It has advantages of sharp cutting, high grinding efficiency, less heat and blockage, less thermal expansion, easy control accuracy, coarse grinding surface and higher cost.

Metal bond diamond grinding wheel has high bonding strength, good wear resistance, low wear, long life, low grinding cost, can bear large load, but poor sharpness, easy to block.

Abrasive particle size has a certain impact on the blockage and cutting amount of the grinding wheel. Compared with fine sand grains, the cutting edge of coarse sand grains with large cutting depth increases in wear, whereas the grinding wheel is easy to block.

The hardness of grinding wheel has a great influence on clogging. With high hardness, the grinding wheel has a high thermal conductivity, which is not conducive to surface heat dissipation, but is conducive to improving machining accuracy and durability.

Concentration selection of grinding wheel is an important characteristic, which has a great impact on grinding efficiency and processing cost. Too low concentration will affect the efficiency, otherwise, grinding particles are easy to fall off, but the concentration range of binder is also.
