Abstract
The invention relates to a method of manufacturing a surgical instrument having a rotatable shaft 2 and a working part 1 disposed thereon, the working part having at least one cutting edge, wherein the shaft 2 and the working part 1 are made of oxide ceramics, characterized in that for the manufacturing of the contour of the instrument, a rough grinding using a grinding tool having a grain size between 40 μm and 110 μm is performed, and subsequently, a fine grinding of the cutting edges using a grinding tool having a grain size between 20 μm and 50 μm performed.

A method of manufacturing a surgical instrument having a rotatable shaft (2) and a working part (1) disposed thereon, the working part having at least one cutting edge, wherein at least the working part (1) is made of oxide ceramics, the method comprising:
- manufacturing a contour of the instrument, including the working part (1), by a rough grinding of the instrument, including the working part (1), using a grinding tool having a grain size between 40 μm and 110 μm;
- and
- subsequent to the manufacturing of the contour of the working part (1), fine grinding the at least one cutting edge in the working part (1) using a grinding tool having a grain size between 20 μm and 50 μm.
