Abstract

1,109,277. Grinding twist drills. MIKROMAT DRESDEN, VEB. 13 Sept., 1965, No. 38944/65. Headings B3B, B3D and B3T. A grinding machine for relieving twist drills comprises an axially-movable sleeve 9 having a dog on each end, the forward dog 16 for engaging a dog 16<1> fixed to the machine frame to locate levers 10, 10<1> on the sleeve to engage the flutes of a twist-drill blank delivered to the machine, and the rearward dog 8<1> for engaging a dog 8 on the work-spindle drive means 6 to ensure correct positioning of the drill in relation to the drive means.
