  • 213 Study on Relationships between Surface quality and Contamination in Grinding Fluid

抄録

In this study, the grinding of SCM 415 steel hardened by carburization and quenching treatments was carried out under supply of coolant included chips or abrasive grains. The correlations between surface quality and contents of chips and abrasive grains were investigated with respect to the number of scratch, surface roughness and grinding forces. The number of scratches gradually increased up to ca. 100/10^2cm^2 against contents of contaminations. In addition, it is noticed that abrasive grains have significant effects on formation of scratches rather than the chips in grinding fluid.
