Overview

The DN Solutions PUMA 5100 B is a heavy-duty 2-axis horizontal turning center that steps up from the 4100 series with a larger swing, more spindle power, and a frame designed to muscle through demanding cuts. With a 21-inch chuck, 650 mm (26 in) max turning diameter, and a 45 kW (60 hp) spindle pushing 4,041 Nm (2,980 ft-lb) of torque, it's built for shops that need to move serious material.

The spindle tops out at 1,500 RPM — this isn't a high-speed machine. It's a torque machine. The 4,041 Nm means you can take deep, aggressive cuts in 4340, stainless, Inconel, and cast iron without the spindle giving up. Box-way construction on X and Z axes keeps the tool stable through interrupted cuts and heavy roughing passes where lighter machines would chatter.

Axis travels are 362 mm on X and 1,105 mm on Z, giving you 992 mm (39 in) of usable turning length. Rapids hit 16 m/min on X and 20 m/min on Z. The 10-station turret handles standard production tooling needs, and the FANUC control provides the programming flexibility that every shop expects.

At 10,600 kg (23,369 lb), the PUMA 5100 B has the mass to back up its cutting capability. That weight translates directly into dampening and stability when you're taking aggressive cuts on large-diameter parts. For shops in aerospace, oil and gas, heavy equipment, and power generation that regularly turn large, heavy forgings and castings, the 5100 B delivers the capacity and rigidity to get through the work without drama.

Strengths & Limitations

Strengths

45 kW (60 hp) spindle with 4,041 Nm of torque handles aggressive heavy roughing in tough materials like stainless and Inconel
21-inch chuck grips large-diameter forgings, castings, and flanges securely for heavy cuts
650 mm max turning diameter provides generous swing for large workpieces
Box-way construction delivers vibration damping and stability during interrupted cuts on demanding materials
10,600 kg machine mass contributes to overall rigidity and chatter resistance
FANUC control with widespread industry support and operator familiarity
Proven PUMA 5100 platform with strong reputation in heavy-duty production environments

Limitations

1,500 RPM spindle speed limits small-diameter work and aluminum machining where higher speeds improve finish
992 mm turning length may be insufficient for long shaft work — consider the LA, LB, or XL variants for longer parts
10-station turret limits tool variety compared to 12-station options on other PUMA models
No live tooling or Y-axis on this variant — milling and off-center features require a second machine
10,600 kg weight requires solid floor prep and professional rigging

Best For

Heavy industry shops turning large-diameter parts in steel, stainless, and cast iron Aerospace and defense manufacturers machining forgings and heavy alloy components Oil and gas shops producing flanges, couplings, and heavy tubular components Power generation and heavy equipment manufacturers turning large castings and shafts Job shops handling heavy, short-to-medium length parts that demand high torque and rigidity

Frequently Asked Questions

01 What's the difference between the PUMA 5100 B and the PUMA 4100 B?

The PUMA 5100 B steps up significantly: 650 mm max turning diameter versus 550 mm, 45 kW spindle versus 35 kW, and 4,041 Nm torque versus 2,379 Nm. Both use box-way construction and FANUC controls. The 5100 B is the choice when your parts are larger and need more cutting power.

02 What does a PUMA 5100 B cost?

New PUMA 5100 B machines typically run $160,000-$220,000 depending on options like programmable tailstock, chip conveyor, steady rest, and tool setter. Used machines from recent years sell in the $70,000-$130,000 range.

03 Can the PUMA 5100 B handle Inconel and other superalloys?

Yes. The 45 kW spindle and 4,041 Nm of torque combined with box-way rigidity make it well-suited for tough materials like Inconel, Waspaloy, and high-nickel alloys. Lower RPM with high torque is the right approach for these heat-resistant materials.

04 What if I need more turning length than 992 mm?

DN Solutions offers the PUMA 5100 LA (2,082 mm), LB (2,042 mm), XLA (3,082 mm), and XLB (3,042 mm) variants for longer work. All share the same 650 mm swing and heavy-duty spindle platform.
