Understanding The Causes Of Grinding Burn Helps

grinding temperature exceeds the tem - pering temperature of the workpiece material. Overtempering causes the workpiece surface to soften. Residual tensile stress is caused by thermal expansion of the workpiece be - yond its yield stress, which puts the ma-terial close to the surface under constant tension. This tension degrades the ma -
