How to choose different bond for diamond wheels

1) Resin-bonded diamond wheels have weak bonding strength, so they have good self-sharpness during grinding, not easy to block, high grinding efficiency, low grinding force, and low grinding temperature. The disadvantages are poor wear resistance and abrasive wear. Large, not suitable for heavy-duty grinding.

2) Diamond abrasive wheels with ceramic bonds have better wear resistance and bonding ability than resin bond, sharp cutting, high grinding efficiency, not easy to generate heat and block, less thermal expansion, easy to control precision, shortcomings, rough surface and high cost.

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

4) Abrasive particle size has a certain effect on the blockage and cutting capacity of the grinding wheel. Compared with fine sand, coarse sand grains have a larger depth of cut.

5) The hardness of the grinding wheel has a greater impact on the clogging. The high hardness of the grinding wheel has a high thermal conductivity, which is not conducive to surface heat dissipation and is conducive to improving processing accuracy and durability.

6) The choice of grinding wheel concentration is an important feature. It has a great impact on grinding efficiency and processing cost. If the concentration is too low, it affects efficiency. On the contrary, the abrasive particles are easy to fall off, but the optimal binder concentration range is also the best.
