Development of electroplated diamond wheel for helical boring of fine ceramics

1^st report: Wheel end profile and state of abrasive cutting edge interference

Abstract

This paper describes the development of an electroplated diamond wheel with longer tool life in the helical boring process of fine ceramics. The states of interference between the wheel end and workpiece were estimated by 3D-CAD. Moreover, force distributions of abrasive cutting edges on the wheel end were analyzed using grinding forces monitored during the process. The results indicated that conventional wheels with flat or ball-shaped end profiles cut with abrasive cutting edges on the wheel end. On the other hand, the wheels with spheroid ends proposed here have longer tool life, twice or more that of convention wheels, because the abrasive cutting edges on the wheel end effectively.
