    Abstract: A drilling/tapping/unscrewing apparatus including a transmission shaft of a power source on which a drilling ratio gear, a tapping ratio gear and an unscrewing ratio gear are mounted for transmitting the power of the power source to a bit. The apparatus further includes an adjustment unit for controlling the switching between the drilling, tapping and unscrewing operations of the apparatus. The adjustment mechanism includes a bit shaft on which a drilling gear, a tapping gear and an unscrewing gear are fitted. The tapping gear and the unscrewing gear are respectively engaged with the tapping ratio gear and the unscrewing ratio gear. The drilling gear and the tapping gear are controlled by an adjustment button to synchronously move up and down on the bit shaft, whereby the drilling gear can be engaged with or disengaged from the drilling ratio gear.

    Abstract: A tapping attachment for a machine having at least one rotating workpiece spindle and associated coaxial tool drive shaft. The tapping attachment couples a tapping tool to the drive shaft in a manner selectively controlling the tool to rotate with respect to a workpiece attached at one of two predetermined velocities in the same direction as the spindle. The attachment is selectively adapted so that one of the two velocities is above and the other below that of the spindle.

    Abstract: A peck-drilling apparatus for quill feed units of the type having a frame member and a tool quill of the type adapted for reciprocative movement with respect to said frame member, together with the usual means to rapidly advance a tool toward a workpiece preparatory to performing a machining operation thereon, means to slowly advance the tool while said machining operation is taking place, and means to rapidly retract said tool at the conclusion of said machining operation, wherein a peck-drilling operation is accomplished by providing a plurality of cam mounting bars fixedly mounted to the tool quill parallel to the axis of reciprocation and having various cams mounted thereon, said cams adapted to operate limit switches fixedly mounted to frame member as they pass thereby. The limit switches, together with a timer, are connected to the various operating means to rapidly advance the tool quill to the workpiece, feed the tool quill at a slow rate of speed for a time interval preset on the timer, and then to rapidly retract the tool quill to its original starting position and there-upon to return it to where the tool just finished cutting previously and again feed the tool for the preset time interval, and to repeat this cycle until the desired depth of cut is reached.
