Tool Life Tests of Ceramic Cutting Tools at Slide Turning

摘要

This article is focused on tool life tests of indexable ceramic cutting inserts at slide turning - cast iron 25P. Five types of cutting materials were tested in total (571, D210, D230, D420, D460) and their tool life was monitored at constant cutting parameters – at slide turning on a turning lathe CMM SLIVEN. Criterion of tool wear was set at VBBmax = 0,6 mm and after every 5th machined workpiece was recorded the conditions of cutting edge. The cast iron 25P was machined material, used for car engines. This work was created in order to meet demand the Saint Gobain Advanced Ceramics Ltd company, Turnov which is producer of these supplied ceramic tools.
