Maximum true run-out deviation is approx. 0.001-0.005mm
The FFBH Series are power-operated on the side of the machine spindle and the corresponding applied counter-force of the tailstock.
The work pieces are clamped centrically by a solid fixed dead center pin, which results in high true run-out accuracy. The datum-point position is in the centre of the work piece.
“Floatingly” born driving devices compensate for uneveness at the face end of the work piece.
Drive pins of type FFBH are compensated hydraulically, achieving best possible true run-out accuracy.
