Cutting Ceramic Materials: Influence of Abrasive Machining and Coating Deposition on the Performance Potential

Abstract

Ceramic cutting tools have a large potential by high speed processing of difficult-to-cut steels and alloys, however due to its fragility they don’t assure the required reliability level of cutting process. For improving the operational characteristics of the ceramic cutting tool combined treatment can be used namely the preliminary planetary grinding of the insert surface and the following deposition of the vacuum-plasma coatings (TiCr)N, (ZrCrHf)N and other.
