40. Decoding the Grinding Zone—A Study on Track Grinding Wheels

Grinding plays a major role in the manufacturing of majority of industrial parts like cutting tool, camshafts, crankshaft, connecting rods, etc. Bearing is one such part where every individual component is ground before final assembly. Grinding of Inner Ring (IR) track of bearing assembly offers a great challenge due to high grinding stock, good surface finish requirement, and profile accuracy. What happens at the grinding zone has always been a black art for years due to lack of scientific understanding. This paper presents an approach to develop Bearing Inner Ring (IR) track grinding wheels by using the output of the grinding diagnostic tools and relating to the microscopic interactions at grinding zone with right combination of grains with special focus on grain shape and structure. Here using the diagnostic tool, signals were collected from grinding interface, data was analyzed and inferences were drawn.
