Description

technical field [0001] The invention relates to a single-excitation elliptical ultrasonic vibration dressing device, which is suitable for the precise and efficient dressing of compact superhard grinding wheels, especially the precise and efficient dressing of diamond grinding wheels and CBN grinding wheels. Background technique [0002] It is difficult to achieve the ideal surface quality and dressing efficiency of high-strength, high-hardness compact grinding wheels using traditional dressing methods. With the common dressing method, the dressing tool and the grinding wheel wear quickly, the dressing efficiency is low, the surface quality of the grinding wheel cannot be guaranteed, and the dressing cost is high. The compact diamond grinding wheel dressing technology developed for various hard and brittle materials processing objects has solved the problem of grinding wheel dressing to a certain extent, but there are still limitations such as low dressing accuracy and dress...
