The paper deals with research concerning optimal technological parameters in diamond burnishing after hard turning by standard tool geometry and by wiper geometry. Burnishing is a less known method, by which the surface of workpiece is finished by a harder tool, without chip removal. Experiments focus on the surface roughness of workpiece, at combination of feed (f) and burnishing force (Fp). We measured also machining forces (Fc, Ff, Fp) at hard turning. Workpiece was made of 100Cr6-type bearing steel with hardness of HRC64.

Modern trends in metal cutting, high speed/feed machining, dry cutting and hard cutting set more demanding characteristics for cutting tool materials. The exposed parts of the cutting edges must be protected against the severe loading conditions and wear. The most significant coatings methods for cutting tools are PVD and CVD/MTCVD today. The choice of the right substrate or the right protective coating in the specific machining operation can have serious impact on machining productivity and economy. In many cases the deposition of the cutting tool with a hard coating increases considerably its cutting performance and tool life. The coating protects the tool against abrasion, adhesion, diffusion, formation of comb cracks and other wear phenomena.
