TechniDrill TBTA-3A-6 Deep Hole Drilling Machine
Description
The TechniDrill TBTA-3A-6 is a deep-hole drilling machine using the BTA process (Boring & Trepanning Association). It can drill a 6-in. diameter hole from solid in a single pass and has 3-axis capability. The machine has applications in the aerospace, mold, and oil & gas industries.
The TBTA-3A-6 has 6 in. (152 mm) of BTA drilling capacity and 48 in. (1,219 mm) of drilling depth. The work table moves horizontally back and forth to provide the X-axis travel, and the drill slide moves vertically on a column to provide Y-axis travel. The spindle motor is available with up to 75 hp. The high-pressure coolant system is rated at 200 GPM of coolant flow and 1,500 psi of coolant pressure.
