摘要 |
A sensor 42d is provided for detecting release of a state of a workpiece fixed and held with workpiece holding members during rotation of a spindle 9. When the release of the state of the wokpiece fixed and held is detected, the sliding members are driven in a direction of an axial center (in a direction as shown by an arrow D) by a reciprocating drive means 42. Even if holding force, such as the oil pressure of the workpiece holding member, is lowered, the decrease of the holding force of the workpiece can be extremely avoided by moving the sliding members in the direction of the workpiece. <IMAGE> |
