Overview

The DN Solutions PUMA 4100 XLA is the extra-long bed variant of the PUMA 4100, stretching the Z-axis to a massive 3,180 mm to handle workpieces up to 3,152 mm (124 in) — that's over 10 feet of turning length. It pairs a 12-inch chuck with the highest spindle speed in the 4100 family at 3,000 RPM, making it the go-to machine for very long shaft work where surface speed matters.

The spindle delivers 35 kW (47 hp) with 1,584 N-m (1,168 ft-lb) of torque. Max turning diameter is 550 mm (22 in). Axis travels are 352 mm on X and 3,180 mm on Z, with rapids at 16/20 m/min. The 12-station turret gives you the full tool complement for multi-zone programs that are common on long shafts with different diameter steps.

At 11,900 kg (26,235 lb) on a 7,024 mm x 2,276 mm footprint, this machine needs over 23 feet of floor space just for the frame — plus loading clearance on the tailstock end for 10-foot workpieces. It runs FANUC control and box-way construction throughout.

The XLA fills a specific niche: shafts, rollers, tubes, and cylindrical components between 5 and 10 feet long that need CNC precision and the ability to maintain surface speed at smaller diameter steps. The 3,000 RPM ceiling means a 3-inch diameter section still gets 900+ SFM, which matters for finishing quality.

For industrial applications like long pump shafts, turbine generator shafts, long hydraulic cylinder tubes, and printing press rollers, the PUMA 4100 XLA eliminates the need for piece-parting or multiple setups. You load the entire workpiece once, program every diameter zone, and run it complete. The programmable tailstock and steady rest support are essential at these lengths.

Strengths & Limitations

Strengths

3,152 mm (124 in) turning length handles shafts and cylindrical parts over 10 feet long in a single setup
3,000 RPM spindle speed maintains surface speed on smaller-diameter steps common on long multi-zone shafts
12-station turret accommodates the full tool variety needed for complex multi-diameter shaft programs
47 hp spindle with box-way rigidity sustains heavy roughing across the entire 10-foot bed length
12-inch chuck suits the medium-diameter shaft work this bed length is typically used for
Single-setup capability eliminates piece-parting, re-chucking, and concentricity issues on long parts

Limitations

7,024 mm (23 ft) machine length demands significant floor space plus additional room for workpiece loading
12-inch chuck limits maximum workholding diameter — step up to XLB (15-inch) for bigger parts
1,584 N-m torque is the lowest in the long/extra-long 4100 family — heavy roughing on large diameters is limited
16/20 m/min rapids across 3,180 mm Z travel means repositioning from one end to the other takes 10+ seconds
Steady rest and tailstock are practically mandatory, adding complexity and setup time

Best For

Shops turning long pump shafts, turbine shafts, and generator components over 5 feet long Hydraulic cylinder manufacturers turning long tubes and piston rods in production quantities Printing press and paper mill equipment shops making long impression rollers and shaft assemblies Wind energy manufacturers turning long blade hubs, main shafts, and yaw system components Industrial equipment builders making long conveyor rollers, process shafts, and drive components Any application where turning 10+ foot workpieces in a single setup eliminates critical concentricity errors

Frequently Asked Questions

01 Why choose the XLA over the standard LA?

The XLA adds over a meter of Z travel (3,180 mm vs 2,155 mm), extending max turning length from 84 to 124 inches. If your parts are between 5 and 10 feet long, the XLA handles them in a single setup. Both have the same 12-inch chuck, 3,000 RPM, and 47 hp spindle.

02 How do I support workpieces at 10+ feet on the XLA?

Programmable tailstock for end support, plus one or more steady rests for intermediate support. On slender shafts (L/D ratio above 8:1), you'll likely need both. The bed is designed for steady rest mounting at multiple positions. Follower rests are also an option for finishing long, slender parts.

03 Is the PUMA 4100 XLA available with a 15-inch or 21-inch chuck?

Yes. The XLB has a 15-inch chuck (2,000 RPM, 2,379 N-m torque) and the XLC has a 21-inch chuck (1,500 RPM, 3,280 N-m torque). All three share the same extra-long bed with 3,150+ mm Z travel. Pick based on your chuck size and speed requirements.

04 What does the PUMA 4100 XLA cost?

New machines run $210,000-$300,000 depending on tailstock, steady rest, chip conveyor, and other options. The extra-long bed commands a premium over the standard-bed and long-bed variants. Used XLA machines appear infrequently on the secondary market since they're typically bought for specific long-term applications.
