Milling with movable center pins and fixed drive heads


Face drivers of type FDNC are power-operated by the thrust of the tailstock. Workpieces are clamped centrically using a movable center pin. This way different centerings can be adjusted, thus ensuring a constant datum-point at the end face of the workpieces.
Machining free from backlash due to fixed drive heads.
Adjustable, spring-loaded center pins provide stability and mounting of high transverse thrust.
For highest run-out requirements it┬┤s possible to adjust the face driver by set screws.

The maximum run-out deviation amounts to approx. 0.02 mm.
