Haas Expands its Line of Drill/Tap/Mill Centers

Haas Automation’s small-footprint DT-1 Drill/Tap Center and DM-1 Drill/Mill Center are well known for their speed, accuracy, and ability to increase throughput while optimizing floor space.

 

Haas has now expanded its successful Drill/Tap/Mill product line with a pair of high-speed, lean-style machining centers – the DT-2 and DM-2 – that provide the same high acceleration rates, fast axis speeds, and short tool change times as their smaller brethren, while offering an additional 8" (203 mm) of X-axis travel and table length – with only a slight increase in footprint. 

 

The new DT-2 and DM-2 are identical in specifications, except for spindle taper and tool changer. The DT-2 is a BT30 taper machine, with a 15,000-rpm inline direct-drive spindle and a high-speed 20+1 side-mount tool changer. It is available with an optional 20,000-rpm spindle. The DM-2 is a 40-taper machine, with a 15,000-rpm inline direct-drive spindle and a high-speed 18+1 side-mount tool changer. The new DT and DM both allow high-speed rigid tapping to 5000 rpm, with up to four times retract speed to shorten tapping cycles.

 

Both machines offer a 28" x 16" x 15.5" (508 x 406 x 394 mm) work cube and a 34" x 15" (864 x 381 mm) T-slot table. The increased table size, longer X-axis travel, and larger work envelope easily accommodate multiple fixtures and multi-spindle rotary tables for increased production and setup flexibility. Yet, their compact footprint still allows multiple machines to be placed side-by-side for efficient use of valuable shop floor space. The spindle on both machines features a 15 hp (11.2 kW) vector drive system that provides 46 ft-lb (62 Nm) of cutting torque. The spindles are coupled directly to the motors to reduce heat, increase power transmission, and provide excellent surface finishes. Cutting feedrates for both machines are 1200 ipm (30.5 m/min), and 2400 ipm rapids and high acceleration rates combine to shorten cycles times and increase throughput.

 

For efficient chip removal, the DT-2 and DM-2 feature 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 rear chip-lift auger is also available for higher-volume applications. A 45-gallon (170 L) flood coolant system is standard, with options for a programmable coolant nozzle, and high-pressure through-spindle coolant systems. A wide selection of options is available to further boost productivity, including high-speed machining software, wireless tool and work probing, 4th- and 5th-axis capability, and much more.

 

Built in the USA by Haas, the DT-2 Drill/Tap Center and DM-2 Drill/Mill Center are backed by the worldwide network of Haas Factory Outlets – the most extensive system of support and service in the industry. For more information about Haas Automation and Haas products, visit www.HaasCNC.com.
