This paper proposes a new grinding-fluid-supply system for improving the grinding performance of a CBN wheel. The system generates cavitations in the fluid flow, which is expected to provide higher cooling and superior grinding-chip removal capability. The system is applied to one-pass surface grinding of steel plates, and residual stress and surface roughness are evaluated. The system has a major effect on improving surface roughness, but has a minor effect on reducing the residual stress under shallow-cut grinding conditions. The effects appear greater under the heavier grinding conditions. |
