ABSTRACT:
A ceramic blank body (2) of a blank (1) is glued on the base (4) of a support (3) of aluminum, which support bears an anchoring part on the side facing away from the blank body (2). According to the invention, the anchoring part is designed as a conical pin (6) which is rotationally symmetrical about a support axis (5). It has a circular engagement groove (7). The base (4) is provided with a bore (8) parallel to the support axis (5). For working the blank, the pin (6) is introduced into a receiving opening (10) of a holding device (9) as far as the limit stop, which is produced by the conical circumferential surface of the pin (6) coming into contact with the analogously conical periphery of the receiving opening (10), and is secured by means of a ball (11) projecting into the engagement groove (7) under the action of an elastic ring (12). A securing pin (13) projects into the bore (8) of the base (4) in order to secure the blank (1) against turning. An ejector (14) arranged at the bottom of the receiving opening is used for removing the blank (1). The blank (1) is secured on a clamp (15), which is pressed by means of a nut (17) against a clamp support (16).
