Haas Automation offers its DT-1 drilling/tapping center with a 20,000-rpm, inline direct-drive spindle, enabling operators to run higher feed rates for small tools and high-speed machining operations. The optional 20,000-rpm spindle is ideal for applications that require high speeds, and powerful enough to mill hard-to-machine materials, the company says. It enables rigid tapping at 5,000 rpm, with four times faster retract speed to reduce cycle times. The spindle is powered by a 15-hp vector drive system that yields 16 foot-pounds of cutting torque, and the motor is coupled directly to the spindle to reduce heat, increase power transmission and provide quality surface finishes. The machine has a 20" × 16" × 15.5" work envelope and 26" × 15" T-slot table. The machine provides cutting feed rates ranging to 1,200 ipm for high-speed milling, and the 20+1 side-mount toolchanger swaps tools quickly to reduce non-cutting time.

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, enabling multiple machines to be placed close together. In addition to the 45-gallon flood coolant system, the drilling/tapping center also includes options for a programmable coolant nozzle and high-pressure through-spindle coolant systems.
