Abstract
322,250. Helin, E. Sept. 6, 1928. Lathes; tools.-In making a locknut, a thread, having a curved axis, is cut in a nut-blank by a cutter of single tooth form having the necessary movement relative to the blank. To allow for the curvature, the blank has a smaller bore than usual. The tool 7, which may be a milling cutter or have a tooth 1, Fig. 5, with a chamfering edge 3, is preferably rotated about the axis b, Fig. 1, while the blank is moved about the centre r and, if desired, kept parallel to itself as shown in Fig. 3. The tool is withdrawn radially during the return of the blank and is then fed radially a greater distance for the next cut. All the movements may be effected by known means on a lathe. Figs. 9 and 10 show nuts, with. exaggerated bend, produced by the two methods.
