DN Solutions PUMA DNT 2600 M

Short, heavy and set up for chuck work with a few milled features: the DN Solutions PUMA DNT 2600M is a 10 in box-way turning center with 610 mm (24 in) of maximum turning length, 680 mm (26.8 in) of Z travel and live tools to 6,000 rpm. It turns up to 380 mm (15 in) in diameter from a 12-station turret.

The same machine exists with a longer bed. The PUMA DNT 2600 LM lists 1,030 mm (40.5 in) of turning length on 1,100 mm (43.3 in) of Z. If the longest part on the schedule fits inside 610 mm (24 in), the shorter machine is the smaller commitment on the floor: 3,355 mm (132.1 in) long and 4,350 kg (9,590 lb), against 3,800 mm (149.6 in) and 4,950 kg (10,913 lb) for the PUMA DNT 2600 LM. Its width is 1,729 mm (68.1 in) and its height 1,780 mm (70.1 in).

At the spindle the table gives 26 kW, 735 N·m and a 3,500 rpm top speed. That pairing favours torque over speed. Large-diameter roughing in steel and cast iron sits well inside it, while small-diameter work in aluminium or brass will run out of surface speed at 3,500 rpm. The chuck is 10 in, with 12 in listed as an option.

Because Z moves are short, rapid traverse decides little of the cycle; the listed rates are 24 m/min (944.9 ipm) on X and 30 m/min (1,181.1 ipm) on Z. In a production cell, what happens around the cut counts for more. DN describes the DNT series as leaving no chip accumulation in the internal machine space, and lists an inverter-type chip conveyor and, as an option, a servo auto door for automation.

There is no Y travel in the table. Rotary-tool work is confined to what X travel of 260 mm (10.2 in) and the spindle centreline can reach, which means bolt-circle drilling on the face, radial holes and tapping, not pockets or offset flats.
