Thermal Analysis of Grinding - ScienceDirect

For High Efficiency Deep Grinding (HEDG) using CBN wheels with large depths of cut and fast workspeeds, preheated material ahead of the grinding zone is removed together with the chips, thereby lowering the temperature on the finished surface. Analytical models have been developed which take all of these effects into account.

Grinding Sparks in Explosive Environments - TFT Pneumatic

Whereas cutting and grinding create sparks by particle removal at high speed that creates frictional heat, welding raises the temperature of a localized area to a level where the material melts. The use of high-temperature gases and electrical arcs in welding means that as no mechanical energy has imparted the distance the sparks travel is reduced.
