Belgium – Haas has expanded its drill/tap/mill product line with a pair of high-speed, lean-style machining centres – the DT-2 and DM-2. They both provide the same high acceleration rates, fast axis speeds and short tool change times as their smaller brethren while offering an additional 203 mm of X-axis travel and table length, with a slight increase in footprint, Haas says. According to Haas, the DT-2 and DM-2 are identical in specifications except for their 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 are built in the US and offer a 508 mm x 406 mm x 394 mm work cube and a 864 mm x 381 mm T-slot table. According to Haas, 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 set-up flexibility. Their compact footprint allows multiple machines to be placed side-by-side for efficient use of valuable shop floor space. The machines are backed by Haas’ network of factory outlets.
