●This machine tool is an internal and external cylindrical grinding machine, suitable for grinding the outer cylindrical surface, outer end face, and inner hole of cylindrical or conical workpieces, especially for the processing of various bearing components.

● This machine tool's worktable features both hydraulic and manual longitudinal movement. The grinding wheel stand and headstock are rotatable. The outer diameter grinding wheel uses a diameter of 400mm, enhancing the grinding efficiency and the lifespan of the grinding wheel.

● The headstock is movable, the grinding wheel stand features micro feed, the hydraulic system employs a low-noise dedicated pump for smooth oil supply, the worktable hydraulic reciprocation has reversing function, enhancing the surface finish during cutting and grinding operations.
