Kays Engineering's TechniDrill TBTA-10-180 is a deep-hole drilling machine using the BTA process (Boring & Trepanning Association).
The machine can drill holes up to 10 inches in diameter from solid using the trepanning process. The machine has applications in both the aerospace and oil & gas industries.
The trepanning process doesn't drill the entire diameter of the hole, only a ring of material on the periphery. Instead of turning all the removed material into chips, a core is left in the center of the hole. This enables the machine to drill larger diameter holes with less required horsepower.
The TBTA-10-180 is a single spindle machine with 10 inches (254 mm) of trepanning diameter capacity and 180 inches (4,572 mm) of trepanning depth. It has the capability for both a rotating tool and a counter-rotating workpiece, both of which are driven by 100 HP motors.
TechniDrill deep hole drilling machines are designed and manufactured by Kays Engineering in Marshall, Missouri, USA.
