METHOD OF TRIMMING AND ROUNDING OF SHARP EDGE CORNERS OF WORKPIECES Russian patent published in 1994 - IPC

FIELD: mechanical engineering. SUBSTANCE: method involves wetting cavities with fluid with added ingredients providing temporary fixation of abrasive medium, placement of workpieces to abrasive medium whose fractions account for 0.1-0.5 of size of cavities and filling cavities with the medium. Then workpieces are machined by loose abrasive and abrasive medium is removed from workpiece cavities by their dipping to solution neutralizing effect of abrasive medium fixation. EFFECT: enhanced operating efficiency and improved machining by filling cavities of threads and gears with working fluid for the period of workpiece machining.
