摘要 |
The invention relates to a rotating tool for machining hardened workpieces, preferably made of steel, consisting of a steel, preferably hardened, parent body (1) with a defined working surface (2) which is provided with a coating (6) of superhard material, preferably boron nitride. In order to provide defined cutting edges in a tool of this type for the precision machining of workpieces with a hardness of up to 62 HRC, the working surface (2) is provided with a multiplicity of micro chip grooves (3) which run parallel to one another, are orientated at an acute angle to a tangent applied to the working surface (2) and have a cross-sectional profile with defined cutting edge (4) and defined chip space (5), the entire working surface (2) being provided with a homogeneous coating (6) of the same thickness of superhard material, preferably boron nitride. …<IMAGE>… |
