Abstract

1,010,620. Grinding. A.C.H. FIBER SERVICE Inc. March 22, 1963, No. 11443/63. Heading B3D. A method of grinding a hollow drill 14 having a continuous exterior periphery 15 comprises rotating the drill about its axis while it is advanced against the grindstone with the end of the drill bearing on the grindstone throughout the thickness of the wall, and stopping the rotating and advancing substantially simultaneously to produce a continuous spiral edge with a shoulder between the high and low ends of the spiral. The drill has a threaded rear end which is received in the threaded end 12 of a holder 11 rotatable and axially movable by means of a screw thread in a support 8. The support is pivotally connected to a base 1 movable along guides on a table 2 by a screw 4. The support 8 is clamped in a desired angular position relative to the base by a screw 9 and the holder advanced to bring the tip of the tool into contact with the grinding wheel. Thereafter, the holder is rotated through 360 degrees to form the spiral edge on the drill, the rotation of the holder being limited by a pin 17 engaging a stop 18. Specification 1,010,619 is referred to.
