The grinding process is commonly used as the final stage of processing. It is used to produce elements that require more tolerance and smooth surface. Considering other processing, such as turning or milling, grinding requires very high energy input per unit volume of material removal. A significant proportion of this energy in the process turns into heat in the grinding zone, which …

"Creep-feed grinding is a process that can deliver more than you realize," Wiss says. With creep-feed grinding, manufacturers can take larger depths of cut than they can with traditional surface grinding. Even added to a slow traverse rate, the material removal rate (MRR) that can be achieved is much higher than that of finish grinding.
