Grinding Out Hardened Parts

1-3-2004A corundum grinding wheel is adequate for the external grinding of the cone. To complete internal-cylindrical grinding in the shortest possible time, a CBN grinding wheel, capable of being dressed at a peripheral speed of 60 m/sec, is used. The CBN grinding wheel is re-profiled after every 100 work-pieces.

Developing a novel binderless diamond grinding wheel

Grinding wheel wear is inevitable during grinding, because of the combined actions of mechanical, physical, and chemical syntheses. A conventional grinding wheel has many types of wear, such as abrasion, crushing, and adhesion clogging, which are due to the structures of the grinding wheels and distribution of the abrasives.

Study on Grinding Processing of Sapphire Wafer

This paper reports our recent results on the diamond grinding process of single crystallized sapphire wafers. It was found that the diamond grains were severely dislodged at the wheel/ workpiece interface and the material was removed by a mixed process of both grinding and lapping. Grinding governed the wafer center while lapping dominated its
