STUDY ON WORKPIECE BURN OF HIGH SPEED TOOL STEEL W18Cr4V

Wen Xiaomin and Zhou Zehua 1st Dept.of Mech.Eng.,South China Univ.of Tech.  
Workpiece burn is an important factor to damage machined surface quality.In this paper,by taking hardened high speed tool steel W18Cr4V as workpiece material,the effects of grinding depth,workpiece speed on workpiece burn are studied,and micro- hardness of the ground surface layer as well as burn colour of the surface are analysed.Through the experiments,some change regu- lations of workpiece burn are recognized and the paper has some guidance to practice to a certain degree.
