Solidified-free dual-phase abrasive particle tool and manufacture method for same

The invention provides a solidified-free dual-phase abrasive particle tool and a manufacture method for the same. A matrix of the solidified-free dual-phase abrasive particle tool is made of 304 stainless steel bars in which a martensite/ferritic structure is left after special local thermal treatment; and iron powder and white corundum abrasive particles are solidified by polyvinyl acetate on a magnetic field of the 304 stainless steel bars. Under reciprocating and circumferential effects of an external rotating magnetic field, the solidified-free dual-phase abrasive particle tool carries outaxial reciprocating motion and axial rotating motion on the inner wall of a deep hole of a work piece respectively. The iron powder and white corundum solidified on the 304 stainless steel bars keepgetting dissolved in a grinding fluid with the polyvinyl acetate, so a solidified abrasive particle state is gradually transformed to a free abrasive particle state. Grinding work is completed by thesolidified abrasive particl
