摘要
Grinding yields high temperature which not only limits the wheel life but also induces tensile residual stresses, micro-cracks, etc. at the ground surfaces. This problem becomes acute when the components are of hard and strong materials and used in dynamic loading. In such cases intensive cooling is essential. In this work various steel specimens have been surface ground under dry conditions, with soluble oil and by a liquid nitrogen jet. Significant improvements in the chip formation mechanism and reduction in specific energy requirement, grinding temperature and residual stress were observed in cryo-grinding when compared with grinding dry and with soluble oil.
