The paper introduces the precision processing technology of grinding using magnetic fluid and presents the working mechanism of magnetic-fluid grinding.Based on Preston equation
it also establishes a mathematical modeling for magnetic-fluid grinding
so as to study relationship between the effects of grinding and the variation of such technological parameters as revolving speed of work-piece
intensity of magnetic field
distance between work-piece surface and magnetic center
grinding time
etc.Analysis on the grinding of Si_3N
4
ceramic-balls proves that the model has been well established.
