DN Solutions PUMA 2600 LYB II

The DN Solutions PUMA 2600 LYB II combines every size advantage the 2600 platform offers: long bed, Y-axis, and big bore. The L means long bed for extended Z-axis travel, Y gives you off-center milling, and B denotes the 12-inch big-bore chuck with a high-torque spindle. For shops that need to turn long, heavy parts with off-center features in tough materials, this is the configuration that covers it all.

The main spindle delivers 26 kW (35 hp) with 1,123 Nm (828 ft-lb) of torque at up to 2,800 RPM through a 12-inch chuck. Max turning diameter is 376 mm (15 in) with 1,245 mm (49 in) of turning length — the long bed gives you nearly double the standard-bed capacity. Z-axis travel runs 1,350 mm (53.1 in).

The Y-axis provides 105 mm (4.1 in) of off-center travel for milling operations. Combined with C-axis positioning and 5,000 RPM live tools on the 12-station turret, you can handle flats, keyways, cross-holes, and other features that would typically require a VMC second op. X-axis travel is 260 mm (10.2 in) with 30 m/min rapids on both axes.

At 7,950 kg (17,527 lb), the LYB II is the heaviest of the standard Y-axis 2600 variants. That mass is your friend when turning long parts in interrupted cuts — the machine stays stable where lighter platforms would chatter. The footprint runs 4,438 mm (175 in) long by 1,945 mm (77 in) wide.

This machine does not include a sub-spindle. The LSYB II variant adds one for backworking. But if your long, heavy parts are single-ended and need the torque advantage of the 12-inch big-bore spindle with Y-axis milling, the LYB II delivers that capability without the added cost and complexity of a sub-spindle.
