Abstract

PURPOSE:To grind drill tips simply and accurately by rocking a drill holder by manipulating a hand wheel provided at one end of a rocking shaft and at the same time by moving the holder longitudinally with a longitudinal feeding of roller of the intermediate section of the rocking shaft. CONSTITUTION:After a drill holder 14 is pulled away from a rocking arm 13 and a screw sleeve 33 is rotated to open up a long jaw 31 to insert a drill, the screw sleeve is rotated to fix the drill to the holder 14. At this time, the position of the direction of the front and rear of the drill is determined by a locator 37, and the drill is mounted so that the direction of the cutting edge of the drill is made to point to the upper right by 10 deg. upwards when looking at the tip of the drill from the front in order to allow for the grinding allowance. Next, the holder 14 is connected to the rocking arm 13 by inserting its long pin 35 and short pin 36 into mounting holes 27 and 28 of the rocking arm 13. Next, a grinding wheel is started, and a longitudinal feed knob 24 is rotated as the rocking arm is rocked by a handwheel 25 to make the tip of the drill get closer to the grinding stone.
