Japanese Patent JP3280048

B2

A ceramic blank component (2) of a blank (1) is attached to the base (4) of an aluminium support (3), which has on the side facing away from the blank component (2) an anchoring part. According to the invention, the anchoring part is designed as a conical pin (6) which is rotationally symmetrical around a support axis (5). It has a round notch groove (7). The base (4) is provided with a bore (8) parallel to the support axis (5). In order to machine the blank, the pin (6) is introduced into a receiving opening (10) of a holding device (9) as far as the stop which is formed by the contact of the conical outer surface of the pin (6) with the similarly conical limit surface of the receiving opening (10) and is held securely by a ball (11) projecting into the notch groove (7) under the action of an elastic ring (12). A locking pin (13) projects into the bore (8) of the base (4) for the purpose of locking the blank (1) against rotation. An ejector (14) arranged on 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 a nut (17) against a clamp support (16).
