Abstract

371,648. Grinding screw threads. LINDNER, H., 57, Fruchtstrasse, Berlin. May 28, 1931, No. 15661. Addition to 329,241, [Class 60, Grinding or abrading &c.]. [Class 60.] A screw thread, for example, on a tap 3, is ground by a tool 1 mounted on an axis parallel to that of the tap and having a multi-ribbed part 2 for rough grinding of the thread, and from one to six ribs 4 for finishing the thread. The part 2 is of the same length as the work 3 and the thread is roughed out by giving the work a single rotation and moving it axially to the extent of one thread, which is then finished by feeding the tool axially from one end to the other of the work, utilizing the ribs 4. The speed of rotation of the tool and of the axial feed may be increased during the finishing operation ; the part 2 may be softer than the part 4. The thread crests are rounded by the ribs 2 and the roots by the ribs 4 ; the diameter of the ribs 4 is greater than that of the ribs 2 to enable the ribs 2 to clear the work during the finishing operation.
