DN Solutions PUMA 2100 Y II

The DN Solutions PUMA 2100 Y II is the Y-axis turning center in the 2100 platform without a sub-spindle. It gives you off-center milling capability on an 8-inch chuck lathe at a lower price point than the full SY II configuration. For shops that need Y-axis milling but handle backworking separately or do not need it, the Y II hits the right balance of capability and cost.

The main spindle runs 22 kW (29 hp) with 358 Nm (264 ft-lb) of torque at up to 5,000 RPM. That is a strong power-to-size ratio for the 8-inch chuck class, and 5,000 RPM gives you excellent surface speed on small to mid-size diameters in both steel and aluminum. Max turning diameter is 406 mm (16 in) with 520 mm (20.5 in) of turning length on the standard-bed configuration.

The Y-axis provides 105 mm (4.1 in) of off-center travel. Combined with C-axis positioning and 5,000 RPM live tools on the 12-station turret, you can mill flats, cut slots, drill off-center holes, and create features that would otherwise require a trip to the VMC. X-axis travel is 260 mm (10.2 in) and Z-axis provides 590 mm (23.2 in), with 30 m/min rapids on both axes.

Without the sub-spindle, the PUMA 2100 Y II is mechanically simpler. That translates to lower acquisition cost, lower maintenance, and simpler programming. If your parts only need work on one end, or you handle backworking on a separate machine, the Y II gives you the Y-axis milling advantage without paying for sub-spindle capability you will not use.

The FANUC 0i-TF Plus control is standard. The PUMA II generation brings improved rigidity and thermal compensation over the older GT and DNT series. This machine competes directly with the Haas ST-20Y, Mazak QT-200MY, and Okuma LB2000 EX II MY in the hotly contested 8-inch Y-axis lathe segment.
