⒈ If the saw blade is not used immediately, it should be placed flat or hung by the inner hole. No other objects or footsteps should be stacked on the flat saw blade, and attention should be paid to moisture and corrosion prevention.
⒉ When the saw blade is no longer sharp and the cutting surface is rough, it must be re-sharpened in time. Grinding cannot change the original angle and destroy the dynamic balance.
⒊ The internal diameter correction and positioning hole processing of the saw blade must be carried out by the manufacturer. If the processing is poor, it will affect the product use effect and may cause danger. In principle, the hole expansion should not exceed the original diameter of 20mm, so as not to affect the balance of stress
⒋ Selection of alloy grinding wheels.
1) The resin bond diamond wheel has weak bonding strength, so it has good self-sharpening during grinding, is not easy to block, high grinding efficiency, low grinding force, low grinding temperature, and the disadvantages are poor wear resistance and abrasive wear Large, not suitable for heavy-duty grinding.
2) The wear resistance and bonding ability of the ceramic bond diamond grinding wheel is better than that of the resin bond. The cutting is sharp, the grinding efficiency is high, it is not easy to generate heat and blockage, the thermal expansion is small, the accuracy is easy to control, the disadvantages are coarse grinding surface and higher cost .
3) The metal bond diamond grinding wheel has high bonding strength, good wear resistance, low wear, long life, low grinding cost, can withstand large loads, but has poor sharpness and is easy to block.
4) The abrasive particle size has a certain effect on the blockage and cutting amount of the grinding wheel. Compared with the fine sand, the cutting edge wear of the abrasive particles with a large cutting depth increases, and the grinding wheel is easy to block.
5) The hardness of the grinding wheel has a great influence on the blockage, and the high hardness of the grinding wheel has a high thermal conductivity, which is not conducive to surface heat dissipation, but it is beneficial to improve the processing accuracy and durability.
6) The selection of the concentration of the grinding wheel is an important feature. It has a great impact on the grinding efficiency and processing cost. The concentration is too low and the efficiency is affected. On the contrary, the abrasive particles are easy to fall off, but the optimal bond concentration range is also the best.
