Embodiment Construction

[0044] figure 1 A cutting machine tool 10 in the form of a deep-hole drilling machine is shown schematically, with a bed 12 , a workpiece holder 14 and a tool holder 16 . The tool holder 16 is rotatable relative to the workpiece holder 14 by means of a rotary drive 18 , in the present case formed by an electric motor. Alternatively or additionally, it is also possible for the workpiece holder 14 to be rotatable. What is important is the relative movement between the work holder and the tool holder. The machine tool 10 comprises an adapter 20 shown in detail in the following figures and a drill 22 with a schematically shown cutting assembly in the form of a blade.

[0045] The machine tool 10 has a pressurized fluid supply unit comprising a cooling lubricant supply unit 24 and a hydraulic fluid supply unit 24a, by means of which cooling lubricant supply unit can be conducted to the drill bit via a cooling lubricant supply line 26 22 and the inner wall 28 of the workpiece 30 ...

Abstract

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).

Description

technical field [0001] The invention relates to a cutting machine tool with the features of claim 1 . According to a second aspect, the invention relates to a knife set. According to a third aspect, the invention relates to a method, in particular a deep hole drilling method, for manufacturing a cylinder with blind and / or stepped holes. Background technique [0002] Manufacturing cylinders usually requires at least three machining processes, namely drilling, cutting and subsequent finishing. The one-sided method can meet the high requirements of the shape accuracy and surface characteristics of the inner wall of the cylinder. [0003] Cylinders with blind and / or stepped bores are particularly complex to produce. The reason is that, especially when drilling, the corresponding chips must be removed. This is only possible with tools in the case of blind holes. For the subsequent scraping and finishing of the inner wall of the cylinder, at least one additional tool is requi...
