Development of Solid-Type Diamond Rotary Dresser Utilizing CVD Diamond Disc - Application to High-Speed Rotary Dresser

摘要

A solid-type diamond rotary dresser utilizing a CVD diamond disc is developed and applied to the dressing of a vitrified CBN grinding quill for internal grinding. This dresser has a feature not found in discrete-type diamond rotary dressers that have been used thus far, which have continuous contact with the grinding quill and exert static dressing force. The solid-type rotary diamond dresser was mounted on a high-speed spindle rotating at 33 m/sec, and basic dressing performance was investigated. It was found that the solid-type diamond rotary dresser has almost the same performance as the discrete-type diamond rotary dresser in terms of grinding force, ground roughness and grinding wheel wear.
