METHOD OF GRINDING MULTI-STEP WORKPIECES Russian patent published in 2001 - IPC

FIELD: mechanical engineering. SUBSTANCE: steps are grinded with coaxial wheels, whose diameters correspond to differences of diameters of the steps to be machined. The working surfaces of the wheels are provided with projections and hollows. The length of cutting projections increases in the direction from the periphery of wheel to its center to provide the constant thickness of removed layer in any cross-section off the steps. Formulae are available for calculating the lengths of cutting projections of the large and small wheels depending on peripheral velocity of limiting worn small wheel, small and large workpiece steps, diameters of wheels and workpiece steps, rotational speed of wheels. EFFECT: enhanced grinding productivity, reduced consumption of abrasive wheel. 2 dwg, 1 tbl
