| 摘要 |
The invention relates to a material-removing machine tool, in particular a deep-hole drilling machine or lathe, having a workpiece holder (14) for holding a workpiece (30), a tool holder (16), a rotary drive (18), by means of which the tool holder (16) can be rotated relative to the workpiece holder (14), an adapter (20), which has a base (20) which is rotationally fixedly connected to the tool holder (16) and has a drive side facing the tool holder (16) and an output side facing away from the tool holder (16), an anti-rotation device (42) for preventing drill head (22) and adapter (20) from rotating relative to each other, and a central, continuous channel (44), through which chips can be transported away counter to a machining direction (B) of the drill head (22), and a drill head (22) which is rotationally fixedly connected to the adapter (20). According to the invention the drill head (22) has a drill head thread (48) and a tapered shaft (50), and the adapter (20) has a union nut (34), which is rotatably fixed to the base (20), and an adapter thread (36) to interact with the drill head thread (48), and a tapered bore (38) to receive the tapered shaft (50). |
