Surface quality of high-speed cutting plates in flat grinding by new abrasive wheels of “Saint-Gobain Abrasive” company

Abstract

Abstract The article detected the surface qualities of high-speed plates – HS10-4-3-10; HS6-5-1; HS18-0-1; W12V3Co10Mo3 and W9Co5 at flat grinding by news abrasive wheels of company “Saint-Gobain Abrasive” – 5NQ46IVS3; 5SG46K12VXP, 5SG46I12VXP, 5SG60K12VXP, TGX80I12VCF5 with using statistical approach. Parameters of surface quality were estimated allowing: microrelief Ra and Sm; form accuracy FLTt and microhardness HV. Because of violation of the condition of homogeneity and normal distribution of variance deviations, nonparametric statistical method was selected for analysis experimental data. According by results of research were recommended using abrasive wheels: 5NQ46IVS3 and 5SG46K12VXP for the formation of parameters Ra, FLTt, HV; and abrasive wheels 5SG46I12VXP and 5SG60K12VXP for the provision parameter Sm.
