The machine adopts advanced creepfeed profile grinding technology, the grinding is realized by reducing the table longitudinal feed speed and increasing the grinding wheel motor power as well as using profile grinding wheel. The workpieces can be formed directly from blank.

Features

■The machine adopts layout principle of horizontal spindle and rectangular table. Two wheelheads carry out vertical elevation movement separately in the middle of the column and simultaneous grinding of the upper and lower faces of the workpieces.

■The machine adopts SIMENS 840D CNC system to realize separate or coordinated control of the table longitudinal movement, vertical movement of the upper and lower wheelheads and the two grinding wheel motors.

■Table longitudinal drive and wheelhead vertical feed adopt AC Servo motor and ball leadscrew pair.

■Wheel spindle adopts imported high precision pre-loaded pair angular contact ball bearings.

■Grinding wheel adopts diamond roller dresser to ensure the symmetry of the upper and lower profile face of the workpieces.
