Deep Hole Drilling Machines



DeHoff BTA/STS 2084

Eldorado KM75-48

Kays Engineering will display the DeHoff BTA/STS 2084 and the Eldorado KM75-48.

BTA Drilling Machine

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).

DeHoff machines are made in the U.S. 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). "This results in superior vibration damping, extended tool life and improved surface finish," said a company spokesperson.

Eldorado KM75-48

The Eldorado KM75-48 is a 3-axis gundrilling machine used to manufacture products like transmission shafts, manifolds and mold matrices. The machine includes updated Beckhoff controls with G-code programming, which provides enhanced flexibility. Complex gundrilling operations can be performed with a single fixturing set-up.

The KM75-48 features a knee fixture table to provide 3-axis CNC gundrilling capability. Drill capacity is 0.078" to 0.75" (1.98 to 19.1 mm). Drill slide travel in the Z-axis is 48" (1,219 mm), with table travel of 24" (610 mm) in the X-axis and 12" (305 mm) in the Y-axis.

Eldorado machines are made in the USA and feature hardened and ground box ways and hand-scraped mating components (versus linear guide ways and milled surfaces). This results in enhanced vibration damping, extended tool life and improved surface finish.
