TechniDrill gundrilling machine for aerospace applications

The TechniDrill 2.00-30-48 is a gundrilling machine used to manufacture airplane aileron actuation cylinders. The actuation cylinder starts as a solid bar. The gundrilling machine drills the large primary hole in a single pass, without the need for a pilot hole. Secondary processes are then utilized to finish the cylinder.

The TechniDrill 2.00-30-48 has a gundrilling diameter capacity of 2.0 inches (50.8 mm) and a maximum gundrilling depth of 48 inches (1219 mm). It features a 30 horsepower AC spindle motor and two-speed gearbox to provide versatile gundrilling performance. The workpiece is counter-rotated during gundrilling via pneumatically operated 3-jaw chucks, which increases the accuracy of the drilled hole.

TechniDrill gundrilling machines are designed and manufactured by Kays Engineering in Marshall, Missouri, USA.
