The highly popular DT-1 Drill/Tap center from Haas Automation, Inc., is now available with a 20000-rpm inline direct-drive spindle, giving customers the ability to run higher feedrates for small tools and high-speed machining operations.

The optional 20K spindle is ideal for applications that require high spindle speeds, and is powerful enough to mill hard-to-machine materials. It allows rigid tapping to 5000 rpm, with up to four times retract speed to reduce cycle times. The spindle is powered by a 11.2kW vector drive system that yields 21.7Nm of cutting torque, and the motor is coupled directly to the spindle to reduce heat, increase power transmission, and provide excellent surface finishes.

The DT-1 is a lean-style machining center with a compact footprint that allows multiple machines to be placed side-by-side, allowing for the most efficient use of valuable shop floor space. It features a generous 508mm x 406mm x 394mm work cube and 660mm x 381mm T-slot table, while maintaining a very small footprint. The machine provides cutting feedrates to 30.5m/min for high-speed milling, and the 20+1 side-mount tool changer swaps tools quickly to reduce non-cutting time. High-speed 61.0m/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.

Built in the USA by Haas, the DT-1 Drill/Tap Center is backed by the worldwide network of Haas Factory Outlets – the most extensive system of support and service in the industry.
