  • THERMAL DAMAGE IN GRINDING

     · King and Hahn (1986) have discussed the influence of wheel speed on grinding power and have determined experimentally that very low or very high wheel speed may require high grinding power. Their results show that optimum wheel speed in most cases is in the range of 8000-10,000 f.p.m.; at higher or lower speeds, thermal damage is more likely to occur.

    The grinding procedure involves several stages, using a finer paper (higher number) for each successive stage. Each grinding stage removes the scratches from the previous coarser paper. This is more easily achieved by orienting the specimen perpendicular to the previous scratches, and watching for these previously oriented scratches to be obliterated.
