Saw Blade Maintenance

1. If the saw blade is not immediately used, it should be laid flat or suspended by the inner hole. Other items or feet cannot be piled up on the flat saw blade, and attention should be paid to moistureproof and rust prevention.

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. The inner diameter correction and positioning hole processing of the saw blade must be carried out by the manufacturer. If the processing is not good, the use effect of the product will be affected, and there may be danger. In principle, the hole reaming should not exceed the original aperture 20mm, so as not to affect the balance of stress.

4. Selection of alloy grinding wheel.

1) Resin bond diamond grinding wheel bond strength is weak, so the grinding self-sharpening performance is good enough, not easy to plug, grinding efficiency is high, grinding force is less, grinding temperature is low, the disadvantage is poor wear resistance, abrasion loss is large, not suitable for heavy load grinding.

2) The wear resistance and bonding ability of diamond grinding wheel with ceramic bond is better than that of resin bond. It has sharp cutting, high grinding efficiency, less heat and blockage, less thermal expansion, easy control precision, coarse grinding surface and high cost.

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

4) Abrasive particle size has a certain influence on the blockage and cutting amount of grinding wheel. Compared with fine sand, the cutting edge wear of coarse sand with large cutting depth increases, whereas the grinding wheel is prone to blockage.

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

6) Grinding wheel concentration selection is an important feature, it has a great impact on grinding efficiency and processing cost, too low concentration will affect efficiency, on the contrary, abrasive particles are easy to fall off, but the optimal concentration range is also the best.
