Chat OnlineSpecific grinding energy causing thermal damage in
Thermal damage that occurs during machining processes is undesirable due to its detrimental effects. Grinding temperatures generated during grinding are a direct consequence of the energy input to the process. Grinding burn is one such type of thermal damage. Excessive grinding temperatures cause thermal damage to the workpiece.

The proportion of the grinding energy entering the workpiece may be analysed either for the whole grinding wheel-workpiece contact zone or for the average grain contact zone which is two orders of magnitude smaller. An analysis which does not clearly apply to one zone or the other introduces conceptual difficulties since the relative speed seen by the workpiece is very different for the two cases.
