Outer Race grinding is a plunge kind of grinding. The grinding time and process quality consists of two aspects: one aspect is the microscopic topography of the surfaces, and the other aspect is the physical and mechanical properties of the surface heat-affected layer material.
In addition, the grinding tem - perature depends on the work-piece (table) speed. With proper coolant application, the tempera - ture can be kept to a minimum at low table speeds, as is the case with creep-feed grinding. T h e t e m p e r a ture can be kept low at high table speeds, too, as in high-e f ficiency deep grinding. HEDG
