Abstract

The contribution deals with testing of exchangeable cutting inserts from coated sintered carbide and determining of chemical composition for their production. The experimental part was based on evaluation of cutting edge insert resistance against heat waves during milling process of stainless steel 1.4301 (X5CrNi18-10). It was determined amount, types and measured lengths each cracks occurred because of heat waves during the milling process for evaluation of proper chemical composition and Cobalt contain for their production.

Keywords: cutting process, inserts, sintered carbide, thermal shock, cracks
