Lathe tool

摘要

The lathe tool has a cooling body (5) of a material with good thermal conductivity, inserted into an opening (4) in the laying surface (3) of the holder (1). The cooling body has a micro-channel structure formed by webs and/or ribs with a width across the coolant flow direction of <= 300 mu m, to form channels with a width across the coolant flow of <= 300 mu m. The coolant channel structure forms the evaporation section of a heat pipe system, and the channels are formed by etching or laser beam working.
