METHOD OF FLAT VIBRATION GRINDING Russian patent published in 2012 - IPC B24B7/02 B24B1/04 B23Q3/15 

FIELD: process engineering.

SUBSTANCE: invention relates to machine building, particularly, to machining of hard-to-machine metals and alloys. Method comprises continuous application of low-frequency and amplitude torsional oscillations to machined billet, said frequency and amplitude matching with grain sizes of diamond abrasive tool. Electromagnetic rectangular plate is arranged on strips from antifriction material, atop the case, to bore blunt hole at the plate center on the side of bottom face. Rotor offset journal is fitted into said hole. Twisted magnetic duct is arranged on rotor end faces with short-circuited secondary. Rotor is incorporated with end induction motor including stator with twisted magnetic core made integral with case lower part that has m₁-phase primary. Said rotor is arranged between magnetic core faces to rotate there between, on support barrel pressed in case lower part central bore.

EFFECT: higher quality and efficiency.
