BTA Drilling Machine Used for Helicopter Manufacturing
May 1, 2018
The DeHoff BTA/STS 2084 is designed for drilling on-center holes using the BTA/STS process. It is being utilized to manufacture drive shafts for helicopter tail rotors. The shaft begins as a solid piece of high-strength alloy steel, and a center hole is drilled in a single pass using the BTA machine. This process results in weight reduction for the finished drive shaft.
The BTA/STS 2084 has a 2" (50.8 mm) diameter drilling capacity and an 84" (2,134 mm) drilling depth. It has a single spindle with a 20 HP spindle motor, and a 4-speed gearbox delivers twice the torque of a standard DeHoff model. The machine can also be offered with slide travels of 36" (914 mm), 60" (1,524 mm) or 120" (3,048 mm).
All DeHoff machines are made in the USA and feature a cast iron drill head base with hardened and ground steel box ways, plus hand-scraped and fitted saddle, gibs and straps (versus linear guide ways and milled surfaces).
