Abstract

1,225,397. Grinding. VSESOJUZNY NAUCHNO-ISSLEDOVATELSKY KONSTRUKTORSKOTEKHNOL - OGICHESKY INSTITUT PODSHIPNIKOVOI PROMYSHLENNOSTI. 29 Aug., 1968, No. 41293/68. Heading B3D. A method of abrasively treating surfaces of hardened steel articles, such as bearing races 1, comprises securing an abrasive tool 3 in the form of a radially movable bar or bars and the article to be machined to respective stocks of a machine tool, and effecting relative rotation at a peripheral speed of 150-200 m./min. and effective longitudinal movement of 1-10 m./min. between the tool and article. As described, a plurality of bearing races 1 are rotated while a tool 4 having a bar or bars 3 is reciprocated within the races to machine the bores thereof which may be cylindrical or tapered. After each double stroke, the bars are shifted transversely to effect a radial feed of 5-10 Á/m. per stroke. The races may be chrome-carbon steel and during machining by bars of corundum do not exceed a temperature of 250‹ C. A mixture of kerosene and spindle oil is used as a coolant and lubricant.
