Abstract

The invention discloses an anti-interference tool for a complex-profile superhard grinding wheel base body and a machining method of the anti-interference tool, breaks through a traditional forming grinding method, and achieves anti-interference precision machining and anti-interference turning machining of a high-precision complex-profile superhard material grinding wheel base body profile through cooperative use of two specially-made precision tools. Various complex profile contours can be conveniently, efficiently and freely switched, the machining cost is greatly reduced, and the machining efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of superhard material processing, and in particular relates to an anti-interference tool for superhard grinding wheel substrates with complex profiles and a processing method thereof. Background technique [0002] For precision grinding of high-precision and complex surfaces, superhard material grinding wheels have the advantages of high precision and the ability to process various complex shapes and contours. , rotor grinding and other fields have more and more broad application prospects. The key features of the above fields are the dimensional accuracy and the complex shape and contour of the grinding part, which requires that the precision of the superhard material grinding wheel must strictly meet the requirements of higher precision. The precision of the superhard material grinding wheel first depends on the machining precision of its substrate. At present, domestic processing of superhard material g...
