The Products performance It possesses the advantages of pores (tiny, middle and large) porous structure, super soft and hardness, and strong grinding force, perfect shape and appearance of parts, high efficiency. It may directly grind from semi-finished part to finished part without milling and planning. The product have been put to use in many aircraft engine factories and get very good remarks Main Purpose 1. Form-grinding the complex surface of anti-high temperature alloy material, e.g..The tenor tooth of the vane for aircraft engine, diesel locomotive, generator set and the gear of transmission. 2. grinding of vicarious stainless steel pad. 3. grinding of viarious surface of measuring tool (quenching tool steel)
