Experimental tool life tests of indexable inserts for stainless steel machining

摘要

The paper is focused on the issue of cutting tools for group of materials M, according to ISO 513, more exactly the area of stainless steel machining. The aim is to analyse and compare the current range of milling tools, namely Pramet Tools and competition (Mitsubishi, Sandvik and Seco). The main objective is to make a practical comparison of selected milling cutters and their inserts. In terms of experimental machining tests an aimed experiment on tool life comparison will be conducted under real cutting conditions in Pramet Tools testing laboratory. Tests are performed on the milling centre - Kovosvit MAS MCV 1270 Power and stainless steel X2CrNiMo17-12-2 was selected as machined material. In conclusion photographs are shown of tool wear on tool faces and flanks, tool wear progress for both groups and final results.
