Overview

The DN Solutions PUMA 2600 LSYB II is the ultimate configuration in the 2600 Y-axis turning center lineup: long bed, sub-spindle, Y-axis, and big bore with a 12-inch chuck. Every letter in the designation adds capability — L for long bed, S for sub-spindle, Y for Y-axis milling, B for big bore. This is the machine for shops that refuse to compromise on any axis of capability.

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. That massive torque handles heavy roughing in stainless, alloy steels, and Inconel without hesitation. The sub-spindle runs at 4,500 RPM with 7.5 kW (10 hp) for backworking operations. Max turning diameter is 376 mm (15 in) with 1,245 mm (49 in) of turning length.

The Y-axis provides 105 mm (4.1 in) of off-center travel. Combined with C-axis and 5,000 RPM live tools on the 12-station turret, you get full mill-turn capability across the entire length of the part. Z-axis travel runs 1,350 mm (53.1 in) and X-axis provides 260 mm (10.2 in), with 30 m/min rapids on both axes.

At 7,950 kg (17,527 lb), the LSYB II is the heaviest standard configuration in the 2600 lineup. The footprint runs 4,438 mm (175 in) long by 1,945 mm (77 in) wide. This mass translates to outstanding stability on heavy, long-reach cuts.

The LSYB II is a specialized machine for specialized work. It handles long, heavy parts with features on both ends and off-center milled geometry in tough materials — think large hydraulic cylinders, heavy-duty couplings, oil and gas components, and defense parts. If your work demands every capability the 2600 platform offers in one machine, this is it.

Strengths & Limitations

Strengths

Maximum capability in one machine: long bed, sub-spindle, Y-axis, and 12-inch big-bore chuck
1,123 Nm of torque handles the heaviest roughing jobs in tough materials without stalling
1,350 mm Z-axis travel with 1,245 mm turning length covers long parts in the 12-inch chuck class
Sub-spindle enables done-in-one production for long parts with features on both ends
Y-axis with 105 mm travel adds off-center milling across the full part length
7,950 kg mass provides exceptional stability for long, heavy workpiece machining

Limitations

Most expensive configuration in the entire 2600 Y-axis lineup
7.5 kW sub-spindle is less powerful than the 10-inch LSY II's 15 kW sub-spindle
2,800 RPM spindle speed limits surface footage on small-diameter and aluminum work
4,438 mm footprint and 7,950 kg weight demand significant floor space and foundation investment

Best For

Shops needing every capability the 2600 platform offers in a single machine for long, heavy parts Oil and gas manufacturers with large-bore, long tubular components requiring milling and backworking Defense contractors producing precision long parts in tough materials with complex geometry Heavy equipment manufacturers with long couplings, cylinders, and shafts needing done-in-one capability Production environments where process consolidation on long parts justifies the premium investment

Frequently Asked Questions

01 What does LSYB stand for?

L = long bed, S = sub-spindle, Y = Y-axis, B = big bore (12-inch chuck). It is the most heavily configured variant in the 2600 Y-axis lineup, combining every available capability into one machine.

02 How does the LSYB II compare to the LSY II?

The LSYB II has a 12-inch chuck (vs 10-inch), 88% more torque (1,123 vs 599 Nm), and more spindle power (26 vs 22 kW). The trade-offs are lower spindle speed (2,800 vs 4,000 RPM), a smaller sub-spindle (7.5 vs 15 kW), and slightly shorter turning length (1,245 vs 1,280 mm).

03 Is the LSYB II overkill for my shop?

If your parts fit in a 10-inch chuck and do not require the extra torque, the LSY II is more cost-effective with a faster spindle and more powerful sub-spindle. The LSYB II is specifically for shops that need the 12-inch big-bore capacity on long parts with full mill-turn capability.

04 What does a PUMA 2600 LSYB II cost?

Expect $195,000-$260,000 new. This is the flagship 2600 configuration and commands a significant premium. However, it replaces what would otherwise be three machines and three setups for complex long parts.
