DN Solutions PUMA 2600 SYB II

The DN Solutions PUMA 2600 SYB II is the big-bore variant of the 2600 SY II, stepping up to a 12-inch chuck while retaining the Y-axis, sub-spindle, and live tooling configuration. The B designation means big bore — a 12-inch chuck with a higher-torque spindle for shops that need more clamping capacity and cutting force than the standard 10-inch SY II provides.

The main spindle delivers 26 kW (35 hp) with a massive 1,123 Nm (828 ft-lb) of torque at up to 2,800 RPM. That is nearly double the torque of the 10-inch SY II (1,123 vs 599 Nm), making it a serious roughing machine in steel, stainless, and alloy materials. The sub-spindle runs at 4,500 RPM with 7.5 kW (10 hp) — smaller than the 10-inch variant but still capable of backside turning, drilling, and finishing.

Max turning diameter is 376 mm (15 in) with 725 mm (28.5 in) of turning length. The Y-axis provides 105 mm (4.1 in) of off-center travel. X-axis travel is 260 mm (10.2 in) and Z-axis runs 830 mm (32.7 in) with 30 m/min rapids on both axes.

The 12-station turret drives live tools at 5,000 RPM. Combined with Y-axis and C-axis, you get the full mill-turn package on a heavy-duty platform. The FANUC 0i-TF Plus control handles the multi-axis coordination.

At 6,200 kg (13,669 lb), the SYB II is a substantial machine built for shops that need the 12-inch chuck's extra clamping force and bore diameter. The trade-off versus the 10-inch SY II is lower spindle speed and a smaller sub-spindle, but the torque advantage is massive. If your parts demand more than a 10-inch chuck can hold, or you are cutting tough materials that benefit from high torque at moderate speeds, the SYB II is the right configuration.
