Pneumatic tapping machine is driven by compressed air, safe, fast and efficient; small pressure and air volume (0.3-0.8 mpa), super-large torsion output;.It can tap various materials such as steel, iron, copper, aluminium and plastics; cylinder with overload protection device, tapping damage is less, screw tooth accuracy is high; operation is simple and light, no need of experience and force at all; processing cost is higher than CNC processing. Core, milling machine with tapper or manual tapping is much lower; heavier workpiece does not need positioning device or movement, and the working area is very large (radius 100-2000 mm); positioning is fast and high cutting speed, increasing production; through hole or blind hole, tapping can not break, vertical, (omnidirectional) angle; processing range is large: (M3-M24). Product, guarantee of service life.
Pneumatic tapping machine is equipped with precise torsion drum clamp with overload protection device. Torsion cylinder clamp adopts the principle of automobile clutch, even if it is blind hole, there is no need to worry about twisting tapping. It can effectively control the twisting force to ensure that the tap is not easy to twist or damage. The accuracy of screw teeth reaches grade 7 or above, and there are no broken teeth or bad teeth when tapping through hole or blind hole.
