Abstract
A holding device on a turning machine for a workpiece, which is held by a chuck serving as a clamping device and being arranged at a receiving disk, is equipped with separate correcting elements disposed at the clamping device. The correcting elements may be controlled individually by electrical, pneumatic or hydraulic means. The correcting elements act on the clamping device in order to adjust the workpiece. It is thereby possible to adjust the clamping device itself in a defined manner, so that the clamped workpiece may be adjusted easily.
Claims12
In a turning machine, in which a workpiece is held in a clamping device that is radially adjustable;
- a holding device comprising:
- a plurality of separate correcting elements, which can be individually controlled by an electric means and act on said clamping device for correcting a clamping position of said clamping device;
- said correcting elements comprising servo-motors, which define longitudinal axes arranged parallel to the longitudinal axis of said clamping device;
- and means including
- a gear means, acting on said clamping device, for transforming the rotation of said servo-motors into a radial adjusting movement for radially adjusting said clamping device.
