Superhard material grinding wheel dressing method and device

Abstract

The invention discloses a superhard material grinding wheel dressing method and device. The superhard material grinding wheel dressing method comprises the steps that firstly, a groove profile of a machined part is preliminarily dressed through electrosparking; the primarily dressed machined part is recorded as a first machined part; rough machining, medium machining and finish machining are sequentially performed on the machined part through a first electrode, a second electrode and a third electrode in an electric spark machining module; the first machined part is precisely dressed through transfer printing cooperation of a diamond roller and a dressing grinding wheel; and finally, a diamond roller is adopted as a dressing tool for a second machined part, and the dressing grinding wheelis replaced to perform precise dressing on the second machined part. Efficient and precise dressing and sharpening of metal-contained superhard material grinding wheels with conductive properties suchas metal binders and composite binders are implemented; the problems that the superhard material grinding wheels are poor in dressing precision and sharpening precision, high in machining efficiencyand the like are solved; and groove shape precision controllable efficient machining and precise sharpening machining of superhard material grinding wheel precise grooves are implemented.

Description

technical field [0001] The invention relates to the technical field of dressing of grinding wheels, in particular to a method and device for dressing superhard material grinding wheels. Background technique [0002] Superabrasive grinding wheels refer to grinding wheels with diamond or cubic boron nitride as abrasive grains. The hardness of the abrasive is much higher than that of corundum and silicon carbide abrasives. The main features are: high hardness, high sharpness, high thermal conductivity, and high grinding efficiency. Under the same conditions of use, the grinding force is smaller than that of ordinary grinding wheels and consumes less power. , saving power; due to the sharp grinding, even when the grinding efficiency is high, the temperature in the grinding area is lower than that of ordinary grinding tools, avoiding defects such as burns and cracks on the working surface, reducing plastic deformation, and ensuring the workpiece being machined The shape, size an...
