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 optimising 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 203mm 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 508 x 406 x 394mm work cube and a 864 x 381mm 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 11.2 kW vector drive system that provides 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 30.5 m/min, and 61 mpm 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 170 litre 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.
