Key Features:
Main uses and scope of application: Mainly used for grinding the inner hole, outer circle, cone surface, end surface of large disc sleeve and housing parts and grinding the inner and outer raceway surfaces of extra-large bearings. Grinding of each surface is completed in one clamping. The position accuracy of each grinding surface is guaranteed. It is a new generation of high-precision and high-efficiency production machine tools. This machine tool is particularly suitable for mass production of extra-large gears, housings, bearing rings, etc.
