CNC DRIVE PINS MILLING, REAR PINS GRINDING, CENTER PINS PROCESSING,CHANGEABLE PINS TURNING
the center pin located on the side of the tailstock pushes the workpiece against the movable center pin of the face driver. the center pin will draw back until the surface of the workpiece bears against the drive pins. In this state the clamping bolt is clamped over the power flow in order to ensure a fixed datum-point during the entire tooling process. the drive pins are floatingly, thus compensating for variations in workpiece, squareness and surface finish. the entire surface of the workpiece can now be finished in one single clamping. drive pins milling, rear pins grinding, center pins processing,changeable pins turning
