Dec 08, 2016 · A downside of centerless grinding is you can't have as many ple axes operating on the workpieces. However, there are many parts where the process addresses the limitations of machining in terms of dimensions, materials, and surface finishes. That's why we like to say that where machining ends, the centerless grinding process begins.

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.
