A method for increasing the wear resistance of metal-cutting tools

Abstract

In domestic machine-building industries, there is a problem with the consumption of metal-cutting tools during machining due to the wear of the cutting edges. This is especially observed in the manufacture of parts from difficult-to-machine materials. The project AR14972884 "Improving the wear resistance of metal-cutting tools by the running-in method" is aimed at solving this problem. Preliminary running in as a method of increasing the durability and reliability of the tool is economically justified in relation to expensive tools, the operation of which is associated with high material and technical costs.
The article presents the results of the study during the operation of worm cutters made of R5M5F for processing gears m=6.0 mm made of steel 12KhGSA. As well as experimental results, reflecting the effect of the speed of preliminary running-in on the durability of a modular worm cutter made of R6M5F, m = 10 mm, when machining a gear made of steel 40X. The results of the study indicate that the method of preliminary running-in of a metal-cutting tool can be considered one of the effective ways to increase tool life.
