MATERIAL-REMOVING MACHINE TOOL, TOOL SET AND METHOD FOR PRODUCING A CYLINDER HAVING A BLIND AND/OR STEPPED BORE

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) to 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).

主权项

1. A material-removing machine tool, comprising:
(a) a workpiece holder to hold a workpiece; (b) a tool holder; (c) a rotary drive by which the tool holder can be turned relative to the workpiece holder; (d) an adapter, comprising
a base connected to the tool holder torque-proofly,an input side facing towards the tool holder and an output side facing away from the tool holder,an anti-rotation device to prevent twisting the drill head and adapter relative to each other, anda central, continuous channel, through which chips can be removed counter to a machining direction of the drill head; (e) a drill head, connected to the adapter torque-proofly, wherein the drill head
has a drill head-thread, anda tapered shaft, and wherein the adapter
(i) has a union nut, that is attached turning to the base and an adapter thread for interaction with the drill head-thread, and(ii) a tapered bore to receive the tapered shaft.
