Abstract
577,028. Dressing ribbed grinders. COVENTRY GAUGE & TOOL CO., Ltd., and JELLIS, M. Oct. 28, 1944, No. 21048. [Class 60] Apparatus for profiling ribbed grinding- wheels includes a stylus co-operating with a diamond tool. running over a rotatable and cylindrical cam which is formed with multistart grooves and has a flattened profile. As shown in Fig. 1, the cam 2 is formed with multistart helical grooves 3 of the same depth but greater pitch than the ribs 4 on a grinding- wheel 5. , The diamond 7 and stylus 6 are carried by a member 8 on a slide 9, while the cam is rotatably mounted in a slide 10. The slides 9, 10 are moved along guides 11, 12 respectively so that as the cam moves one pitch axially, the tool moves one pitch of the ribs 4, either by differential screw mechanism, not shown, or by face cams 15, 16 rotated either by hand wheel 20 or by power from the main shaft 26 through a shaft 25. A cam with a pitch n times that of the grinding-wheel as n starts, is rotated at <1>/nth the speed of the grinding-wheel, and is traversed axially at n times the speed of the tool 7. A cam 24 withdraws the tool from the grinding-wheel during the return movement. In one modification, the cam has movement of rotation only and the slide carrying the tool and stylus is moved, by rack-and-pinion mechanism attached to a differential gear on the driving shaft, one pitch of the ribs 4 while the cam rotates one pitch of the grooves 3. In a further modification, the cam, with a movement of rotation only, has the same pitch as the ribs 4 but less depth and a lever is provided to increase the depth component of the tool. In a still further modification used to grind annular ribs, the grinding-wheel is independently rotated and the cam, which is axially stationary, is rotated through gearing interconnected with the main slide and is formed with grooves of the same depth as, but with the pitch a multiple of the ribs on the grinding-wheel.
