This paper researches the influence of the cutting edge’s geometry and coating on its durability. Four types of edge geometry and two types of coating are studied as well as the influence of abrasive material on production of the chamfer.
Modern machines allow to position cutting tools relative to the workpiece with an accuracy of 1 micron, but increasing of producing detail accuracy can be achieved only by an increase of sharpness of the cutting tool, which will guarantee allow to cut required metal pads of the size of 2 … 5 microns, and will reduce the time spent on finishing operations. Existing manufacturing techniques and sharpening of cutting tools let to receive the sharpness of the blade up to 10 microns. A further increase of sharpness is only possible with the use of high-speed sharpening.
This paper suggest a high-speed approach of producing of ultra-disperse powder. The approach is completed with special
tool and cutter grinding machine, with computer numerical control (CNC).

The possibility of obtaining ultra-disperse powders by high speed way with a particle size that does not exceed the declared value. The research of the mechanical method of obtaining ultra-disperse powders. Dispersion of obtained powder was defined for various materials. The dependence of the dispersion of the obtained powder was indentified from the choice of abrasive tools on Bakelite and metal bonds.
