A numerically controlled grinder special for slewing bearing processing comprising a grinder body and a workbench, a column and a grind head assembly, a grinding wheel dresser, a numerical control system and a cooling system. The grinder body and the workbench comprise working turntable components including a working turntable seat, a working turntable and a turntable motor. The working turntable components are mounted on an X-axis rail of the grinder body and moves on the X-axis left to right driven by an X-axis servo motor and a ball screw mounted inside the grinder body to complete grind feed processing of the X-axis. A workpiece mounted on the working turntable is driven by the turntable motor to rotate with the turntable to complete rotate feed processing. The grind head assembly comprises a grind head motor, a grind head component is composed of a rotary grind head seat and a grind head grinding wheel; and the grind head motor is mounted on the rotary grind head seat, and the grind head grinding wheel is driven by a main shaft of the rotary grind head seat to rotate so as to complete grind processing. The surface of the grinding wheel can be trimmed to be in a shape of slewing bearing rolling grooves by the grinding wheel dresser. By the aid of the numerically controlled grinder, the inner and outer cycle faces, the rolling grooves and a mounting plane of the slewing bearing can be clamped and grind processed in one step synchronously.read more
