Abstract

306,711. Hughes, V. A. B., (Cincinnati Grinders, Inc.). Feb. 25. 1928. Centreless grinding; wheels; guides and rests. -Machines for polishing cylindrical work, comprise a regulating wheel rotating at low speed, and having an operative surface of a substantially non-yielding nature, a relatively soft operating wheel rotating at a high speed and having an operative surface of a yielding nature, and integral work support. The bed 20 of the machine is provided with guides 21, 22 for slides 23, 24, which are adjusted to and from each other by hand wheels and screws 42, 44 and carry bearings for the regulating wheel 34 and operating wheel 28 respectively. The former is composed of an annular ring of fibrous material compressed to present a hard surface to the work and the latter is also composed of fibrous material such as canvas but built up in flat layers so as to present a soft surface to the work and have a polishing action only. The work is supported by a blade 35 and guides 38, 39, all being lined by a soft material such as leather so as not to injure the work. The leather may be attached to the blade and guides by glue. The axis of the regulating wheel 34 is inclined to the horizontal at an angle of about 6‹ to feed the work axially whilst rotating it. and the rate of feed may be increased by inclining the support 35 through its adjustable end connections 36, 37. The regulating wheel engages the work tangentially, making a line contact therewith but the operating wheel engages the work over a considerable surface. The diameter of the work is not reduced appreciably during its passage through the machine but foreign materials which are in the nature of a minute film produced by oxidation are removed.
