ABSTRACT
Precision grinding is more akin to the grinding of the past and that which is most familiar to the industry. The abrasive processes associated with precision grinding, internal diameter (ID) and outside diameter (OD) grinding, and reciprocating surface grinding for example, are neither designed, nor is it their intent, to remove large quantities of material. Abrasive machining encompasses a number of grinding processes—creep-feed grinding (CFG), continuous-dress creep-feed grinding (CDCF), high efficiency deep grinding (HEDG) and very impressive performance extreme removal (VIPER)—that use both conventional as well as superabrasive grinding wheels. Precision grinding and abrasive machining today are materials-driven technologies, but they also hold advantages over traditional methods of machining. As metals became more difficult to machine, because of their hardness, crack sensitivity, work-hardening, abrasion resistance, and the need for higher surface integrity, abrasive machining began to compete both technically as well as economically with the large chip-making processes.
