Cutting tool for machine tools, in particular milling cutter

摘要

In a cutting tool for machine tools, in particular a milling cutter, the basic tool body (2), to increase its thermal conductivity, has a hollow space (6) extending from its free end (2a) roughly up to the tool holder (4) which can be fastened to the spindle of the machine tool. The inner wall of the hollow space (6) is provided with a capillary structure (7), is evacuated and is filled with a small quantity of liquid. A heat-dissipating device in the form of a heat exchanger (8) is arranged at the tool-holder-side end (2b) of the basic tool body (2).
