Description

Technical Field

[0001] The utility model relates to the technical field of grinding wheels, in particular to a grinding disc forming die for a CBN grinding wheel. Background Art

[0002] The forming die is a forming mechanism used in the production of CBN grinding wheels. CBN grinding wheels use cubic boron nitride abrasive as raw material, and use metal powder, resin powder, ceramic and electroplated metal as binders to make products of various shapes. The tools used for grinding, polishing and grinding are called CBN abrasive tools. CBN has more advantages than diamond grinding wheels in processing ferrous metals. Forming dies are required for the production of CBN grinding wheels.
