An adaptive precision chuck for a precision/ultraprecision machining system is described. The chuck (200) defining a mount for receiving a workpiece (300) wherein, when in use, the centre of the mount is configured to be substantially concentric with an axis of rotation (214) of the machining system, the chuck (200) further including jaws (201) about the mount and a plurality of compliant flexures (203-206) configured, upon application of rotational forces by the machining system to the chuck about the axis of rotation (214), to engage the jaws (210) upon a workpiece (300) in the mount.

The present disclosure improves the accuracy of matching the center of the workpiece with the rotation center of the chuck. It provides a chuck correction method for a chuck including a body, a plunger, and jaws, the body including a rear body and a front body provided in a front side of the rear body, the plunger provided inside the body and configured to move along an axis of the body, and the jaws each configured to move in a radial direction of the axis while guided by the front body along when the plunger moves, the chuck correction method including: a correction step including moving the front body in the radial direction of the axis with a position of the rear body keeping with respect to the axis in a state that a workpiece is clamped in the jaws.

A flexible coupling for attaching a collet to a draw bar includes a draw bar having a first longitudinal axis and a first coupling portion. The first coupling portion includes two or more legs spaced apart from one another with each of the legs having first coupling surface formed thereon. The flexible coupling includes a collet having a second longitudinal axis and a clamping portion proximate one end of the collet. The collet includes a second coupling portion proximate a second end of the collet. The second coupling portion has a second coupling surface formed thereon and configured in a shape complementary to the first coupling surface so that the first coupling surfaces moveably engage the second coupling surface such that the first longitudinal axis and the second longitudinal axis are coaxial when an axial force is applied to the draw bar and the collet.
