Abstract
A cylindrical workpiece to be machined by grinding can be positioned particularly accurately when the workpiece is supported on at least one, preferably two static support elements and immobilised in a collet of a spindle, allowing both wobbling to be compensated and the spindle axis to be radially shifted relative to the longitudinal axis of the workpiece.

Abstract
The invention relates to a clamping device (1) for fixing a steady rest (45), said clamping device having a support (10), which has an annular sliding surface (20), and a ring (30) contacting the sliding surface (20) and having a web (35) running in the radial direction, at one end of which web at least one wing (32) is arranged, having a bearing surface complementary to the sliding surface (20). Said clamping device enables a precise fixation of a pin connected to the ring if the clamping device has an abutment (50) which encloses, together with the ring (30), at least one cavity (80) for a fluid on the side of the wing (32) facing away from the sliding surface (20). The cavity (80) can be placed under pressure via a fluid duct (81) that can communicate with the cavity (80), such that the wings (32) are tensioned against the sliding surface (20).

- B23Q 1/32 - Relative movement obtained by co-operating spherical surfaces, e.g. ball-and-socket joints
- B23Q 1/54 - Movable or adjustable work or tool supports using particular mechanisms with rotating pairs only two rotating pairs only
- B23Q 1/76 - SteadiesRests
- B23Q 3/08 - Work-clamping means other than mechanically-actuated
