An apparatus for chucking a work carrier (2) on a chuck (1) which can be fixed to a machine tool is provided with positioning means (11) for centring the work carrier (2) with respect to the chuck (1), and with a chucking apparatus, the chucking force of which holds the work carrier (2) fixedly on the chuck (1). The chucking apparatus comprises a plurality of chucking units (10) which are distributed over the circumference of the chuck (1) and can be fastened independently of one another on a base part (3) of the chuck (1). The chucking units (10) each have a chucking jaw which can be moved from a release position into a chucking position. This enables a chucking force which is appropriate for operation to be produced, and also allows universal use of the apparatus. |
