A New Preparation Method for Resinoid-Bonded CBN Wheels

Summary Truing and dressing for super-abrasive wheels are extremely difficult because of their high degree of hardness. In this study, a new preparation method for resinoid bonded super-abrasive wheels, in which truing and dressing were integrated, were developed. By adopting the developed equipment, these two conditioning processes can be carried out simultaneously, and therefore, non-machining time can be reduced considerably. A metal bonded diamond wheel and steel wire brushes were combined to make up the preparation tool. Through a series of fundamental experiments, a recommended preparation condition has been established from the viewpoint of the truing as well as the dressing efficiency and wear resistance of the preparation tool.
