Abstract

835,989. Centreless grinders. CINCINNATI MILLING MACHINE CO. Oct. 23, 1958 [April 21, 1958], No. 33924/58. Class 60. In a centreless grinder the grinding wheel 15 and regulating wheel 30 have conical peripheries and the interposed work rest 61 has an inclined surface so that the grinding throat has the shape of a truncated cone, and power operable means are provided for feeding work into the grinding throat in timed relation to the rotation of the regulating wheel, The regulating wheel 30 is of solid metal and its front face has a recessed outer margin 55c in which are secured, by bolts 67, two arcuate cams 66 each having a face cam surface extending beyond the periphery of the front face of the regulating wheel 30. The cam surface comprises a forward dwell portion 69a, a rear dwell portion, and a central feed portion which moves a workpiece 65, e.g. a tapered roller for a roller bearing, towards the smaller end of the grinding throat. Two notches 75 are cut in the rim of the regulating wheel, one at the rear of each cam 66, and these receive and eject the finished workpieces. The regulating wheel may have only one notch or more than two, there being a corresponding number of cams. The angular velocity of the regulating wheel is indicated by a tachometer dial 38. The grinding wheel is trued by a diamond tipped bar 251 threaded in a sleeve 24 slidable in a body 23 mounted on ways 22 on a slide 21 swivelling on base 25. A cam 27 on slide 21 controls movement of the sleeve.
