Rockford Ettco Procunier's high-speed, high-volume tapper is for those who need the productivity of a versatile independent drilling and tapping machine without the expense of a CNC machine. Servo position control provides rapid advance and retraction, which substantially reduces cycle time, according to the company. This control flexibility enables a tap to be retracted twice as fast as it enters a workpiece and eliminates the need for a lead screw. The unit is also available with multiple spindle heads.
