Grinding

Face drivers of type FFBR/FBSR 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.

By loading and unloading the workpieces the drive pins get retracted. The drive pins are „floatingly“, thus compensating for variations in workpiece, squareness and surface finish. The drive pins are floating by suspended, thus compensating irregularities with regard to possible unevenness of the surface of workpiece. For possible grinding wheel overrun, the face driver nose cone is cylindrically set down. For highest run-out requirements it´s possible to adjust the face driver by set screws. The maximum run-out deviation amounts to approx. 0.002-0.006 mm. 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.

Face drivers of type FFB/FFBH 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.

The maximum run-out deviation amounts to approx. 0.002-0.01 mm.
The tailstock force should be approx. 30% higher than the force of the clamping cylinder to ensure safe clamping.
