Abstract

This paper presents a study of tool life, process forces and surface integrity. The focus is on the continuous turning of biocompatible cobalt chromium using ceramic cutting inserts and different cooling systems. The goal when using cooling lubricants with tungsten carbide tools is on the one hand to extend tool life time and on the other hand to achieve a better surface quality on the workpiece. When using ceramic cutting tool materials usually cooling lubricants are dispensable. The heating of the component and thus the reduction in strength is desired, since the ceramic cutting materials withstand higher temperatures. Tool life of ceramic cutting materials without cooling lubricants is often rather low. Therefore, cooling lubricants should help to extend the tool life. It will also be investigated how the different cooling systems affect the surface integrity of the workpiece. The investigations were performed under constant cutting parameters.
