METHOD OF VIBRATION GRINDING Russian patent published in 2012 - IPC B24B1/04 B24B7/02 B06B1/18 

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. Device is used with its case top provided with washer made from antifriction material that doubles as antifriction bearing and rectangular plate is arranged to support workpiece. Bracket is arranged on bottom face of said plate and rigidly connected with waveguide incorporated with mechanism of impulse-oscillatory loading of billets made up of hydraulic pulse generator. Hammer of the latter is arranged to act on waveguide to generate the plate crosswise oscillations. To orient motion in horizontal plane, helical compression spring of pulse loading mechanism is used to return plate with workpiece, bracket and waveguide after hammer impact into initial position.

EFFECT: higher quality and efficiency.
