Overview

The DN Solutions PUMA 5100 LYA is the long-bed, 15-inch chuck variant with Y-axis capability in the PUMA 5100 heavy-duty turning platform. It takes the proven 5100 LA base — 650 mm swing, 37 kW spindle, long-bed Z travel — and adds a programmable Y-axis for off-center milling operations on large, heavy parts that would be impractical to move to a secondary machine.

The spindle delivers 37 kW (50 hp) with 2,432 Nm (1,794 ft-lb) of torque at up to 2,000 RPM. Max turning diameter is 650 mm (26 in) with 2,042 mm (80 in) of turning length on the long bed. The 15-inch chuck provides solid clamping on medium-to-large diameter workpieces while maintaining 2,000 RPM for reasonable surface speeds across a range of diameters.

The Y-axis provides +/-80 mm (160 mm total, 6.3 in) of off-center travel — larger than the 3100 series due to the bigger machine platform. Combined with the 12-station turret running live tools at 4,000 RPM and C-axis positioning, you can drill off-center bolt patterns, mill flats, cut keyways, and tap holes along the full length of parts approaching 2 meters. When your workpiece weighs 500 kg or more, eliminating the crane lift to a VMC isn't just saving time — it's a fundamental safety and quality improvement.

X-axis travel is 362 mm (14 in), Z is 2,155 mm (85 in). Rapids run 16 m/min on X, 20 m/min on Z, and 8 m/min on Y. Box-way construction throughout provides the rigidity this class demands. At 12,100 kg (26,675 lb), the machine has serious mass behind it. The FANUC 0i-TF Plus control handles the multi-axis coordination with standard Y-axis G-code programming.

Strengths & Limitations

Strengths

Y-axis with 160 mm travel brings off-center milling to the heavy-duty 5100 long-bed platform
2,432 Nm torque and 37 kW spindle handle aggressive roughing on large-diameter parts
2,042 mm turning length accommodates long shafts and rollers with milled features
15-inch chuck with 2,000 RPM balances clamping force with surface speed flexibility
Eliminates dangerous and time-consuming crane lifts to secondary machines for milling operations
Box-way construction and 12,100 kg mass provide stability during heavy mill-turn operations

Limitations

2,000 RPM spindle speed limits high-speed finishing on small-diameter features
12,100 kg requires reinforced foundations and professional rigging
Y-axis adds significant cost over the non-Y PUMA 5100 LMA variant
5.9 meter footprint demands dedicated floor space planning

Best For

Power generation shops machining long turbine shafts with keyways, flats, and bolt patterns Oil and gas manufacturers producing large valve bodies and pump shafts with milled features Heavy equipment builders turning large-diameter shafts with cross-holes and off-center features Marine component manufacturers needing mill-turn capability on propeller shafts and drive components Job shops handling large, heavy parts where moving to a VMC is impractical or unsafe

Frequently Asked Questions

01 How does the PUMA 5100 LYA compare to the 5100 LMA?

The LYA adds a 160 mm Y-axis for off-center milling. All other specs — spindle, chuck, bed length, turret — are identical. The LMA has C-axis milling only (on-center). If your parts need off-center drilled or milled features, the LYA eliminates secondary VMC setups.

02 What does a PUMA 5100 LYA cost?

New machines run $265,000-$345,000 depending on options. The Y-axis adds roughly $25,000-$35,000 over the comparable LMA. The ROI comes from eliminating crane lifts and secondary setups on heavy parts.

03 How does the 15-inch chuck LYA compare to the 21-inch LYB?

The LYA uses a 15-inch chuck at 2,000 RPM with 2,432 Nm torque, while the LYB steps up to 21-inch chuck at 1,500 RPM with 2,958 Nm torque. Choose the LYA when your parts fit within the 15-inch grip and you benefit from the higher RPM ceiling.

04 Can the Y-axis handle heavy milling or just light operations?

The Y-axis with 4,000 RPM live tooling handles production-level milling operations. It's not a machining center replacement for heavy pocketing, but it's fully capable of milling flats, keyways, cross-drilling, and tapping on large turned parts. The box-way construction provides the rigidity for these operations.
