Abstract
Grinding processes are generally utilized for finishing hard and brittle materials with a view to achieving both high accuracies and stock removal rates. As a result of the mechanisms involved in grinding hardened steels, virtually all of the input mechanical energy is transformed into heat energy. When grinding hardened parts, the proportion of heat entering the work-material can lead to thermal damage, but in grinding unhardened materials it may be possible to use the heat for surface hardening of components. This paper deals with the investigation toward proving this idea as a realistic possibility. The primary experiments prove that advanced grinding processes are suitable for surface strengthening of soft-annealed or tempered parts. This new kind of heat treatment process called “grind-hardening” will be illustrated in this paper.
