Overview

The DN Solutions PUMA 3100 LSY is the top-of-the-line configuration in the 3100 Y-axis turning center platform: long bed, sub-spindle, and Y-axis on a 12-inch chuck with 30 kW (40 hp) and 1,123 Nm (828 ft-lb) of torque. It is built for shops that need to produce complex long parts with features on both ends and off-center milling — all in a single cycle without manual intervention.

The main spindle runs at up to 3,000 RPM with 30 kW of power, paired with the 12-inch chuck for maximum clamping force on larger workpieces. The sub-spindle operates at 4,000 RPM for backworking — backside turning, drilling, tapping, and finishing happen automatically after part transfer. Max turning diameter is 420 mm (16.5 in) with 1,285 mm (50.6 in) of turning length on the long-bed platform.

The Y-axis provides 130 mm (5.1 in) of off-center travel, the most generous in the PUMA Y-axis lineup below the 4100 class. 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 293 mm (11.5 in), with 30 m/min rapids on both axes.

At 8,500 kg (18,739 lb), the 3100 LSY is the heaviest variant in the 3100 lineup. The footprint runs 4,530 mm (178 in) long by 2,067 mm (81 in) wide. That mass translates to exceptional stability on heavy interrupted cuts across long workpieces.

The FANUC 0i-TF Plus control handles the multi-axis coordination between main spindle, sub-spindle, Y-axis, and turret. The 3100 LSY represents the most capable long-bed done-in-one turning center in the DN Solutions lineup before stepping up to the PUMA 4100/5100 heavy-duty class.

Strengths & Limitations

Strengths

Maximum capability in the 3100 platform: long bed, sub-spindle, Y-axis, 40 hp, 12-inch chuck
30 kW spindle at 3,000 RPM with 1,123 Nm torque handles tough materials at production feeds
1,350 mm Z-axis travel covers long parts up to 1,285 mm turning length
Sub-spindle enables automatic part transfer and backworking for done-in-one production
130 mm Y-axis travel provides generous off-center milling capability
8,500 kg mass delivers outstanding stability for long, heavy workpiece machining

Limitations

Most expensive configuration in the 3100 platform
4,530 mm footprint and 8,500 kg weight require significant floor space and foundation
3,000 RPM spindle speed may limit small-diameter high-speed aluminum work
Complex multi-axis machine requires skilled programming and experienced operators

Best For

Shops producing complex long parts with features on both ends and off-center milled geometry Oil and gas manufacturers with heavy-duty tubular components, couplings, and valve bodies Aerospace and defense contractors with precision long parts in tough materials Heavy equipment manufacturers needing done-in-one capability for shafts and cylinders Production environments where process consolidation on large parts justifies the premium investment

Frequently Asked Questions

01 How does the 3100 LSY compare to the 2600 LSYB II?

The 3100 LSY has 30 kW at 3,000 RPM versus the 2600 LSYB's 26 kW at 2,800 RPM. It offers a larger turning diameter (420 vs 376 mm), more X-axis travel (293 vs 260 mm), and 25% more Y-axis travel (130 vs 105 mm). The 3100 also has more turning length (1,285 vs 1,245 mm). It is the clear step up for shops needing more all-around capability.

02 What does a PUMA 3100 LSY cost?

Expect $210,000-$280,000 new depending on options. It is the premium configuration in the 3100 lineup. However, it replaces what would otherwise be multiple machines and setups for complex long parts.

03 Is the 3100 LSY or a PUMA 4100 a better choice?

The PUMA 4100 steps up to a 15-18 inch chuck class with significantly more torque and spindle power. If your parts fit within the 3100 12-inch chuck and 420 mm turning diameter, the 3100 LSY is more cost-effective. The 4100 is for shops that genuinely need the larger platform.

04 Can I use a steady rest with the sub-spindle?

Yes, a steady rest can support the part during main spindle operations before transfer to the sub-spindle. This is recommended for very long, slender parts with high length-to-diameter ratios to prevent deflection and chatter.
