摘要

A method of machining a drum-shaped workpiece (37) whereby the workpiece (37) is fastened to a rotatable holder (1) of a machine tool (3), and a centreline (51) of the workpiece (37) coincides substantially with an axis of rotation (19) of the holder (1). According to the method, the workpiece (37) is fastened to the holder (1) by means of an adhesive (45), for example a mixture comprising rosin and beeswax, this adhesive (45) being exclusively provided between the holder (1) and a support surface (47, 49) of the workpiece (37) directed substantially parallel to the centreline (51), the workpiece (37) being brought into connection with the holder (1) exclusively via the adhesive (45). It is achieved thereby that mechanical stresses in the workpiece (37) caused by the fastening of the workpiece (37) to the holder (1) are as small as possible. A dimensional accuracy which the workpiece (37) has after being machined by the machine tool (3) and before being removed from the holder (1) thus remains intact when the workpiece (37) is removed from the holder (1).
