Abstract

PURPOSE: To easily perform changeover operation of chip cutting with a knob and improve workability of drilling work through a drill, by such constitution that an automatic chip cutter is built in a drilling machine itself from the beginning.
CONSTITUTION: The upper end part of a spindle 3 fitted into the spindle sleeve of a drilling machine is constituted to a spline shaft. The first planetary gear 14, meshed to and rotated by a master gear 13, is mounted in a movable state through a needle bearing 16 to the lower stage peripheral surface S2 of a pin shaft 15 provided with a flange F in its intermediate part, further the second planetary gear 19 is mounted in a movable state through a needle bearing 20 to the upper peripheral surface S1 of the shaft 15. Then in a rotary process of the spindle 3, a differential gear 24 is differentially rotated, and a roller 27 falls in a groove 28 at a certain revolution of the spindle 3 to instantaneously remove a gap. In this way, changeover operation of cutting can be easily performed.
