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

Abstract:

Article Preview

A solid-type diamond rotary dresser consisting of 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 the other discrete-type rotary dressers used thus far, in which it continuously contacts the grinding wheel and leaves a spiral on the grinding wheel surface. The solid-type diamond rotary dresser was mounted on a low-speed spindle supported by journal bearings, and its dressing performance was compared with those of two discrete-type rotary diamond dressers: a dressing roll on which surface single diamond grains are brazed and a dressing roll made of a metal-bonded diamond wheel. It is found that the solid-type diamond rotary dresser tends to bring about rough grinding conditions among the three dressers.
