The redesigned DeHoff 2072TC from Kays Engineering (Marshall, MO) is a gundrilling machine with 5-axis capability. The gundrilling spindle is mounted on a traveling column to provide the X-axis and Y-axis movement. A CAT 40 spindle is also mounted on the traveling column to enable secondary operations like milling and tapping. The machine is ideal for drilling complex hole patterns, like those seen in heat exchangers, manifolds and molds. Features include:
- A 2-inch (50.8 mm) gundrilling capacity and a 72-inch (1829 mm) slide travel.
- A traveling column that provides 60 inches (1524 mm) of X-axis travel and 46 inches (1168 mm) of Y-axis travel.
- Workpiece fixturing options including a stationary T-slot table and a rotary table with self-centering hydraulic vises. 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).
- 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 accuracy and surface finish.
- Standard elements such as a high-pressure coolant system and Beckhoff controls with G-Code programming capability.
