Turning with fixed center pins in a face driver
Face drivers of type FFB/FFBH/FFP are power-operated on the side of the machine spindle as well as the side of the tailstock. The workpieces are clamped centrically by the fixed center pin. This operation results in high true run-out accuracy. The datum-point is located in the center of the workpiece.
Drive pins of type FFB/FFBH/FFP are hydraulically activated and compensated, thus achieving excellent true run-out accuracy.
The maximum run-out deviation amounts to approx. 0.001-0.005 mm.
The tailstock force should be approx. 30% higher than the force of the clamping cylinder to ensure safe clamping.
Our practiced design and consulting teams will be glad to assist you in finding a suitable clamping device as well as identifying the correct clamping thrust.
