ABSTRACT:
A method and device for fine profiling or shaping tools coated with super-hard material, for example cubic crystalline boron nitride or diamond, especially tools coated with a single layer and having a prescribed or predetermined profile or shape. The rotatably driven tool is profiled or shaped in the region of the cutting surface by a clustered electron or laser beam which is controlled in a course corresponding to the prescribed shape or contour of the tool, and is oriented tangential to the tool; the profiling is accomplished by vaporization of the crystal tips or points which project from the desired profile. The cutting surface may be roughened in conformity to the desired profile after the fine profiling or shaping thereof. The rotatably drivable tool, and the device which produces the electron or laser beam, are mounted in such a way that a relative movement can be carried out along a prescribed path or course between the tool and the electron or laser beam, which is oriented tangential to the tool.
