DeHoff BTA/STS 2084 Drilling Machine
The DeHoff BTA/STS 2084 is designed for drilling on-center holes using the BTA/STS process.
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 a significant weight reduction for the finished drive shaft.
The BTA/STS 2084 has a 2-inch (50.8 mm) diameter drilling capacity and an 84-inch (2134 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 inches (914 mm), 60 inches (1524 mm) or 120 inches (3048 mm).
