Description
Technical field
The present invention relates to magnetic grinding Material Field, especially a kind of exceptional hardness magnetic abrasive grain and preparation method thereof.
Background technology
Magnetic grinding (Magnetic Abrasive Finishing, abbreviation MAF) processing technology is the new work of skin processing
Skill, new technology.It is to form " flexible magnetic using the externally-applied magnetic field gravitational attraction magnetic abrasive grain acted between grinding tool and workpiece
Brush ", to improve workpiece surface quality.
In high-accuracy surface is ground, this method has preferable flexibility, adaptivity, self-sharpening, controllability.Wen Sheng
It is small, without metamorphic layer, processing quality is high, efficient and tool without carrying out wear-compensating, without correction of the flank shape the features such as, widely apply
In manufacturings such as machinery, mold, automobile, bearing, semiconductor and aviations, but since magnetic abrasive is to lapping efficiency, essence
Degree, surface quality play decisive role, restrict magnetically grinding processing technology and deeply promote.Thus develop processing effect it is good,
Magnetic abrasive at low cost, with long service life, to pushing the fast development of magnetically grinding technology to have great importance.

Technology develops and widely applied key link, and the research of magnetic abrasive technology of preparing is imperative.
And currently, magnetic grinding efficiency existing in the prior art is low, magnetic abrasive prepare difficult, of high cost etc. because
Element has done many research and probe work in terms of magnetic abrasive preparation, has developed a variety of preparation methods in succession, such as bond both at home and abroad
Method, sintering process, plasma powder fusion method, simple and mechanical mixing method etc., make the technology of preparing of magnetic abrasive obtain larger hair
Exhibition.But it prepares problem with regard to the magnetic abrasive of function admirable, large-scale industrial production to be solved at all not yet.Also locate in China
In the research and development primary stage, achievement in research does not integrate with market.Magnetic abrasive prepared by mull technique, due to being needed in advance to product
Briquet is wanted, the equipment such as the electric furnace containing inert gas, laser machine are needed.Although mull technique method and process is simple, it is real to be easy
It is existing, cost is relatively low, but tissue looseness, associativity is poor, density is low, thermal stability is poor, abrasive grain is mutually easy to fall off, and the service life is shorter, and
The magnetic abrasive that is bonded when temperature is higher makes the table of processing form furvous, and original finished surface is easy contaminated damage etc.
The defects of.
