Cooling Capability of Cutting Fluids in Grinding

Abstract

Grinding is a machining process used in the production of components with high precision tolerances and smooth finishes. It is an extremely complex process in which the main difference between grinding and other process is the relatively large contact area between the abrasive grits and the workpiece surface. The large contact area will cause difficulties supplying cutting fluids to the grinding arc, which leads to high energy input per volume of material removed. Since most of this energy dissipates as heat, a high temperature will occur. This will not only produce thermal damage and reduce the precision and quality of the workpiece surface, but also cause wear of the grinding wheel [. Therefore, the use of a process fluid in grinding is imperative in most cases.
