Abstract

1384792 Grinding SOC NOUVELLE DE ROULEMENTS 23 May 1972 [15 July 1971] 24214/72 Heading B3D A centreless grinding machine comprises a rotatably driven bearing surface for axially engaging a workpiece 1, Fig. 1, and having a horizontal axis of rotation S, a pair of radial bearing shoes 5, 6 disposed angularly to each other against which the workpiece is urged by having its centre la disposed eccentric in relation to the axis S, the bearing mid-point of the shoes being located on a half-circumference overlying the axis 1a of the workpiece, a grinding wheel 7 which urges the workpiece with radial pressure against at least one of the shoes, and means 9 for feeding workpieces to the bearing surface and shoes. As applied to an internal centreless grinding machine, the workpiece 1 is urged against the driven bearing surface by magnetic or mechanical pressure, the shoes 5, 6 positioning the workpiece so that its centre 1a is eccentric to the centre S of the bearing surface so that it is urged against the shoes. The workpieces 1, 2, 3, 4 are successively fed to the bearing surface from an inclined trough 8 by a V-shaped portion 9 carried by the rod 10 of a piston disposed in a cylinder 11, the portion having a side member 12 on which successive workpieces roll as the portion is advanced to feed a workpiece to the bearing surface. During advance of the portion 9, the magnetic or mechanical pressure is discontinued so that a lever 13, rocked about a pivot 14 by the workpiece 2 being fed engaging a roller 16, pushes the ground workpiece 1 into a discharge shoot 17. An embodiment for external centreless grinding is similar to that shown in Fig. 1 but, in order to avoid a long travel of the piston-rod, the cylinder is mounted on a pivot and the V-shaped portion has a roller bearing on an inclined cam.
