Product Description

The machine adopts mainly the wheel periphery for surface grinding, and the wheel end surfaces can also be used for grinding grooves and the sides of projections.

Features

■Cross table layout principle, small thermal deformation

■Reversible and variable vane pump driven for table longitudinal movement, closed hydraulic system.

■Roller guideways for saddle cross movement, cross feed controlled by AC frequency motor with stepless speed regulation to realize fine intermittent feed and continuous movement.

■Throttle-hole type hydrostatic bearings for wheelhead spindle
