In order to obtain a surface roughness of a mirror surface, the wheel more favorable low rigidity

Rigidity support abrasive shape accuracy and surface roughness to ensure high shape accuracy of the wheel should be as rigid as possible. However, in order to obtain a surface roughness of a mirror surface, the wheel is more advantageous low rigidity. synthetic diamond powder the perspective of a rigid tool, ultra-precision mirror grinding requirements are contradictory. Rigid metal bonded grinding wheel, to ensure favorable shape accuracy, but it is not easy processing of the degree of synthetic diamond of the mirror, dressing difficult to achieve this level, the grinding accuracy and rigidity requirements are very demanding. High elasticity of the resin binder, with vibration absorption, and easy to make highly uniform cutting edge prominent; resin grinding wheel during grinding abrasive rotary phenomenon occurs with authigenesis effect.
