The DT-1 Drill/Tap center from Haas Automation, Inc., is now available with a 20,000-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 for applications that require high spindle speeds, and powerful enough to mill hard-to-machine materials. It allows rigid tapping to 5,000 rpm, with up to four times retract speed to reduce cycle times. The spindle is powered by a 15 hp vector drive system that yields 16 ft-lb of cutting torque, and the motor is coupled directly to the spindle to reduce heat, increase power transmission, and provide improved 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 shop floor space. It features a 20" x 16" x 15.5" work cube and 26" x 15" T-slot table, while maintaining a very small footprint. The machine provides cutting feedrates to 1,200 ipm for high-speed milling, and the 20+1 side-mount tool changer swaps tools quickly to reduce non-cutting time. High-speed 2,400 ipm 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 45-gallon flood coolant system is standard, with options for a programmable coolant nozzle and high-pressure through-spindle coolant systems.
