Haas Automation’s small-footprint DT-1 drill/tap center and DM-1 drill/mill center are known for their speed, accuracy and ability to increase throughput while optimizing floor space, the manufacturer says.

Haas has now expanded its 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 DT-2 and DM-2 are identical in specifications, except for spindle taper and toolchanger. 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 toolchanger. 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 toolchanger. The new DT and DM both allow high-speed rigid tapping to 5,000 rpm, with as much as 4× retract speed to shorten tapping cycles.

Both machines offer a 28" × 16" × 15.5" (508 × 406 × 394 mm) work cube and a 34" × 15" (864 × 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 shopfloor space.
