The machine adopts the cross plate layout, and the transverse guide rail is attached with teflon foft belt. Closed hydraulic system is adopted for the movement of the worktable. The forward and backward feed can be manually fed or the screw can be driven by the motor to automatically feed intermittently. The downward movement of the grinding head can be achieved by using the lifting motor for quick lifting(AHR) or the servo motor for quick lifting and automatic feeding(AHD), which can also be accomplished manually. The machine adopts precise angular contact rolling bearing, high rigid sleeve structure, the overall quality of the machine is stable, smooth operation.
