Product Details
These NC control 5-deg equally dividing heads have respectively the center height as 140, 175, 220mm and are the necessary accessories for the NC millers, NC borers and other machine tools. They can be mounted on the working-table of the machine tool either horizontally or vertically. The clamping can be actuated either hydraulically or pneumatically. While the spindle is unclamped, the NC controlling system can perform the dividing at angles of integer times of 5 degrees by being driven by the servo motor and the feedback of the encoder.
