Overview

The DN Solutions PUMA 5100 LMA is the long-bed, 15-inch chuck variant in the PUMA 5100 series — a big-bore turning center designed for parts up to 650 mm (26 in) in diameter and 2,042 mm (80 in) in length. If you're turning large flanges, valve bodies, pump housings, or long shafts that exceed the swing of a 4100-class machine, this is where you step up.

The spindle delivers 37 kW (50 hp) with 2,432 Nm (1,794 ft-lb) of torque at a max speed of 2,000 RPM. That's serious grunt for heavy roughing in carbon steel, alloy steel, and cast iron. The 15-inch chuck on a large-bore spindle means you can clamp big raw stock securely, and the torque ensures you're not babying your depth of cut on interrupted surfaces.

The LMA gets a 2,155 mm (85 in) Z-axis travel, which is the long-bed configuration. X-axis cross travel is 362 mm (14 in), giving you room to swing the full 650 mm turning diameter. Rapids are 16 m/min on X and 20 m/min on Z — appropriate for a machine of this mass class. The 12-station turret runs live tools at 4,000 RPM for drilling, tapping, and milling without re-chucking.

Box-way construction throughout the machine provides the vibration damping and rigidity that large-diameter turning demands. When you're taking 5 mm depth of cut passes on a 500 mm diameter forging, you need a machine that won't chatter or deflect. The PUMA 5100's mass — 11,700 kg (25,790 lb) — works in your favor here.

The FANUC 0i-TF Plus control is standard, offering the same programming environment as every other PUMA in the lineup. Shops running a fleet of DN Solutions machines can move operators between machines without retraining. Specs sourced from DN Solutions published data.

Strengths & Limitations

Strengths

650 mm (26 in) max turning diameter accommodates large forgings, castings, and flanges that won't fit on 4100-series machines
2,432 Nm (1,794 ft-lb) of torque handles aggressive roughing on large-diameter parts in tough materials
2,042 mm max turning length covers long shaft and roller work in the long-bed configuration
12-station turret with 4,000 RPM live tooling adds milling capability without secondary setups
Box-way construction and 11,700 kg mass provide excellent vibration damping for heavy interrupted cuts
FANUC 0i-TF Plus control maintains operator consistency across multi-machine DN Solutions shops

Limitations

2,000 RPM max spindle speed limits surface speed on small-diameter features
11,700 kg requires solid foundation preparation and professional rigging for installation
Higher cost than the PUMA 4100 long-bed variants for the additional swing capacity
No Y-axis standard — off-center milling capability requires the Y-axis option or a different machine
Large footprint may require shop layout modifications to accommodate

Best For

Valve and pump manufacturers turning large housings, bonnets, and bodies up to 26 inches in diameter Power generation shops machining turbine components, generator housings, and large rotor shafts Oil and gas manufacturers producing BOP stacks, wellhead components, and large-diameter tubular parts Heavy equipment builders turning large wheel hubs, bearing housings, and structural components Job shops needing large-swing turning capability with long-bed flexibility for varying part lengths Forge shops and steel service centers finishing large forgings and castings to final dimensions

Frequently Asked Questions

01 What's the difference between the PUMA 5100 LMA and the PUMA 5100 MA?

The L in LMA stands for long bed. The LMA has 2,155 mm (85 in) of Z-axis travel versus 1,105 mm (44 in) on the MA. Max turning length is 2,042 mm vs 992 mm. Choose the LMA if your parts exceed about 1 meter in length; the MA saves floor space and weight for shorter parts.

02 How does the PUMA 5100 compare to the Okuma LU7000?

Both are large-swing horizontal turning centers in a similar class. The PUMA 5100 LMA typically comes in at a lower price point with strong FANUC-based controls. The Okuma uses their proprietary OSP control, which some shops prefer. Rigidity and capability are competitive between the two — the decision often comes down to dealer support and control preference.

03 Can I add a steady rest to the PUMA 5100 LMA?

Yes. Hydraulic steady rests are a common option for supporting long shafts and preventing deflection during turning. DN Solutions offers both fixed and follow rest configurations that mount to the bed. For shafts with high length-to-diameter ratios, a steady rest is practically mandatory for holding tolerance.

04 What coolant system comes standard?

The PUMA 5100 LMA comes with a standard flood coolant system. High-pressure coolant options up to 70 bar are available for improved chip breaking in deep-hole drilling and tough material turning. An oil skimmer and chip conveyor are common add-ons for production environments.
