Pneumatic tapping machine will tap from M3 to M32 in Steel ,Stainless Steel,Copper, Aluminum, Plastic material and so on. The taps are held in a quick change collet system driven by a pneumatic motor. The motor is mounted on a articulated arm which maintains parallel motion. The smooth arm action allows the tap to be brought into position swiftly and easily. The pneumatic motor is equipped with a chuck and each tap is held in its own collet. Each collet has a ratchet clutch, the torque is preset for each size of tap preventing tap breakage. The clutch system will allow blind holes as well as through holes to be tapped. The torque clutch allows the tap to stop turning when it encounters any obstruction that may cause tap breakage. With the increase in speed over hand tapping and removing tapping operations from manual and CNC machinery, our tapping arm will prove to be an affordable alternative.
