Abstract

706,331. Taps. FINLAYSON, E. D. Nov. 23; 1951 [Dec. 12, 1950], No. 30317/50. Class 83 (3). [Also in Group XXIII] In grinding the taper nose of a tap 23 by turning the tap about its axis and also moving it laterally of its axis towards the grinding wheel 24 to produce backing off, the tap is simultaneously given a movement in the direction of its axis so as to produce a spiral or helical eccentric relief.
