Overview

The DN Solutions PUMA 3100 SY is the standard-bed sub-spindle Y-axis variant in the 3100 turning center platform — a 12-inch chuck machine that combines high torque, Y-axis milling, and sub-spindle backworking for done-in-one capability on larger parts. If you have outgrown the 2600 class and need more clamping force and rigidity with full mill-turn functionality, the 3100 SY is the step up.

The main spindle delivers 30 kW (40 hp) with 1,123 Nm (828 ft-lb) of torque at up to 3,000 RPM. That is more spindle power than the 2600 SYB II (30 vs 26 kW) at a higher top speed (3,000 vs 2,800 RPM), giving you better performance across a wider range of part sizes. The sub-spindle runs at 4,000 RPM for backworking operations including backside turning, drilling, and finishing.

Max turning diameter is 420 mm (16.5 in) with 765 mm (30.1 in) of turning length. The Y-axis provides a generous 130 mm (5.1 in) of off-center travel — 25% more than the 2600 platform's 105 mm. That extra Y-axis range opens up larger milled features and wider off-center hole patterns. X-axis travel is 293 mm (11.5 in) and Z-axis gives you 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 the larger Y-axis travel, C-axis, and sub-spindle, the 3100 SY provides serious mill-turn capability that can handle parts previously requiring a dedicated multi-tasking machine. The FANUC 0i-TF Plus control is standard.

At 7,000 kg (15,432 lb), the 3100 SY has significant mass for vibration damping. The footprint is 3,908 mm (154 in) long by 1,978 mm (78 in) wide. This machine bridges the gap between the mid-size 2600 platform and the heavy-duty PUMA 4100/5100 series, giving you 12-inch chuck done-in-one capability without the cost and footprint of the larger machines.

Strengths & Limitations

Strengths

30 kW (40 hp) spindle with 1,123 Nm torque at 3,000 RPM provides more power and speed than the 2600 SYB
Done-in-one capability with Y-axis, sub-spindle, and live tooling on a 12-inch chuck platform
130 mm Y-axis travel is 25% more than the 2600 class — handles larger off-center features
420 mm max turning diameter exceeds the 2600's 376 mm for stockier parts
293 mm X-axis travel provides more clearance for larger workpiece diameters
7,000 kg mass delivers excellent stability and vibration damping

Limitations

Significantly more expensive than the 2600 SY II or SYB II configurations
765 mm max turning length may be limiting — step up to the LSY for longer parts
3,908 mm footprint is larger than the 2600 standard-bed machines
3,000 RPM spindle speed is moderate for small-diameter high-speed work

Best For

Shops that have outgrown the 2600 class and need more torque, diameter, and Y-axis travel Production environments requiring done-in-one 12-inch chuck capability for mid-to-large parts Aerospace and defense manufacturers with complex parts needing Y-axis milling and backworking Heavy equipment and automotive tier suppliers with flanges, housings, and gear blanks Shops seeking a step up from the 2600 platform without jumping to PUMA 4100/5100 heavy-duty machines

Frequently Asked Questions

01 How does the 3100 SY compare to the 2600 SYB II?

The 3100 SY offers 30 kW at 3,000 RPM versus the 2600 SYB's 26 kW at 2,800 RPM. It has 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). Both share 1,123 Nm of torque. The 3100 is the clear upgrade path for shops needing more capability.

02 What does a PUMA 3100 SY cost?

New machines run $185,000-$250,000 depending on options. That places it above the 2600 SYB II but below the PUMA 4100 sub-spindle configurations. The 3100 SY offers significant capability for the investment.

03 Is there a long-bed version?

Yes, the PUMA 3100 LSY adds long-bed capability with 1,350 mm of Z-axis travel and 1,285 mm of turning length. If your parts exceed about 700 mm, the LSY gives you the extra reach with the same spindle, Y-axis, and sub-spindle configuration.

04 What is the sub-spindle capable of?

The 4,000 RPM sub-spindle handles backside turning, drilling, tapping, and finishing. After main spindle operations, the part transfers automatically to the sub-spindle for B-side completion. This eliminates manual rechucking and second-op setups.
