Abstract

334,828. Lindner, H. Feb. 27, 1929, [Convention date]. Screw - threads, grinding. - A screw thread is ground by a roller having a number of annular grinding ribs 5 and arranged with its axis parallel to the axis of the screw. In order to produce the correct shape of teeth, the ribs have their crests 3 rounded to a smaller radius than that of the root c of the thread, and the roots 4 are rounded to a larger radius than that of the crest d of the thread, the flanks 1, 2 of the ribs being, slightly curved and joining tangentially the curves of the crests and roots.
