DeHoff 2072TC Gundrilling Machine Has Five-Axis Capability

Kays Engineering Inc.’s DeHoff 2072TC is a gundrilling machine with five-axis capability. The gundrilling spindle is mounted on a traveling column to provide the X-axis and Y-axis movement while a CAT 40 spindle is also mounted on the traveling column to enable secondary operations like milling and tapping. According to the company, the machine is ideal for drilling complex hole patterns, like those seen in heat exchangers, manifolds and molds.

The 2072TC has a 2” (50.8-mm) gundrilling capacity and a 72” (1829-mm) slide travel. The traveling column provides 60” (1524 mm) of X-axis travel and 46” (1168 mm) of Y-axis travel.

Workpiece fixturing options include a stationary T-slot table and a rotary table with self-centering hydraulic vises, the company says. The rotary table provides B-axis rotation, and is mounted on a W-axis slide to provide clearance when rotating a long workpiece. Load capacity for the entire work table is 9,000 lbs (4,082 kg).

According to the company, the machine features a cast-iron drill head base with hardened and ground steel box ways, plus hand-scraped and fitted saddle, gibs, and straps (versus linear guideways and milled surfaces).
