Description

technical field

[0001] The invention belongs to the technical field of powder metallurgy, and relates to the preparation of a high-hardness alloy material, in particular to a method for preparing an alloy polishing disc material used for processing and dressing diamond tools and diamond grinding wheels. Background technique

[0002] Since diamond is the hardest substance in nature and has strong chemical inertness, it is recognized as one of the difficult-to-machine materials. However, it is precisely because diamond has unique physical and chemical properties that the tools it prepares play an irreplaceable role in the field of precision and ultra-precision machining. Tribochemical polishing is a new diamond polishing method that combines mechanical and chemical polishing. Due to its simple equipment, high processing efficiency and low process cost, it has great development prospects in the field of diamond product processing. The core content of tribochemical polishing te...
