Research into Dry Turning of Welded Surface by Replaceable Cutting Insert with Closed Loop Heat Removal

A special tool has been devised incorporating a closed loop system based on Peltier thermoelectric couples to cool replaceable hard alloy inserts. Experimental research has been done into dry turning of a X20Cr13 steel welded surface with a SECO cubic boron nitride circular plate at the cutting speed increasing from 100 to 300 m/min. It has been determined that Ra surface roughness decreases by 22% while Rz surface roughness goes down by 26%; in addition, the wear flat of tool tips diminishes by 17%. © 2018 Published under licence by IOP Publishing Ltd.The work was supported by Ministry of Education and Science of the Russian Federation, contract № 02.G25.31.0148 with Sverdlovsk Instrumental Plant within the framework of Research and Development Project No Н979.210.007/15, July 28, 2015 for the federal autonomous educational institution of higher education “Ural Federal University”
