Haas Automation has boosted the spindle speed of its very successful DT-1 Drill/Tap centre from 12,000 rpm to 15,000 rpm, giving customers the ability to run higher feed rates for small tools and high-speed machining operations.

The DT-1 is a compact, high-speed drill and tap machine with full milling capabilities. The machine features a generous 508mm x 406mm x 394mm work cube and 660mm x 381mm T-slot table, while maintaining a very small footprint. The powerful BT-30 taper spindle now spins to 15,000 rpm, and allows rigid tapping to 5000 rpm, with up to four times retract speed. The spindle is coupled directly to the motor for smooth, quiet operation and extreme thermal stability. An 11.2kW vector drive system provides 62Nm (peak) of cutting torque for milling and boring operations.

The DT-1 provides cutting feed rates to 30.5m/min for high-speed milling, and the machine's 20+1 side-mount tool changer swaps tools quickly to reduce non-cutting time. High-speed 61m/min rapids combine with high acceleration rates to shorten cycle times and increase throughput.

For efficient chip removal, the DT-1 features steeply sloped internal sheet metal. Optional twin chip augers transport chips to exit at the rear of the machine, allowing multiple machines to be placed close together. A 170L flood coolant system is standard, with options for a programmable coolant nozzle and high-pressure through-spindle coolant systems.
