Grinding Machines an overview ScienceDirect Topics

Grinding spindle drives of surface grinding machines require steplessly adjustable numbers of rotation speed up to about 10,000 min –1. In dependence on the grinding wheel diameter, cutting speeds of about 400 m/s are achieved so that high speed machining conditions are reached. The spindle power of surface grinders depends on the field of application and may amount up to 80 kW. Coolant

Grinding and Polishing ASM International

Grinding uses fixed abrasives—the abrasive particles are bonded to the paper or platen—for fast stock removal. Polishing uses free abrasives on a cloth; that is, the abrasive particles are suspended in a lubricant and can roll or slide across the cloth and specimen. A book edited by Marinescu et al. describes in detail the scientific aspects of ceramic abrasion processes. Some companies
