Pneumatic Tapping Units
The ability to vary torque and feed rate independently on Airmachines’ Self Feed Units provides the unit with a unique characteristic. It can function as a lead screw tapper, using the tap itself as the lead screw.
Two types of tapper heads are available. The heavy-duty head on the 600 and 900 rpm units is capable of tapping up to 3/8″ threads. The medium duty head on the 1500 rpm unit is capable of tapping up to 1/4″ threads. Positive drive chucks are available with flex collets, see Flex Collet chart at the right.
