Overview

The DN Solutions PUMA 4100 LMA is the long-bed, 12-inch chuck version of the PUMA 4100 series — a serious production turning center built for shops running mid-to-large parts that need both reach and rigidity. With 2,060 mm (81 in) of max turning length and a 550 mm (22 in) max turning diameter, this machine handles long shafts, cylinders, and tubular components that shorter-bed lathes can't touch.

The spindle puts out 37 kW (50 hp) with 1,024 N-m (755 ft-lb) of torque at up to 3,000 RPM. That's production-grade power — you can push hard in steel and stainless without watching the load meter nervously. The 12-inch (305 mm) chuck grips securely, and the A2-11 spindle nose is standard for this class of machine.

Axis travels are 352 mm (14 in) on X and 2,155 mm (85 in) on Z, with rapids at 16/20 m/min. The 12-station turret runs live tooling at 4,000 RPM for cross-drilling, tapping, and milling. Having milling capability on a machine with over 2 meters of Z-travel means you can put cross-holes and features along the full length of a shaft without moving it to a machining center.

At 11,050 kg (24,361 lb), the PUMA 4100 LMA is a substantial machine that needs proper foundations. But that mass is working for you — the heavy castings and rigid construction soak up vibration and hold tolerance during heavy cuts. The FANUC 0i-TF Plus control manages the turning and milling operations.

This machine fills the gap between the mid-range PUMA 2600 and the heavy-duty PUMA 5100. If your shop regularly turns parts in the 12-inch chuck range with lengths over a meter, the 4100 LMA gives you the reach, power, and rigidity to do it efficiently.

Strengths & Limitations

Strengths

2,060 mm (81 in) turning length handles long shafts and tubular work that shorter lathes can't
37 kW (50 hp) with 1,024 N-m torque gives production-grade cutting authority in tough materials
12-inch chuck and 550 mm swing cover mid-to-large parts in a single setup
Live tooling at 4,000 RPM adds milling capability across the full length of the work envelope
Heavy 11,050 kg construction provides excellent vibration damping and rigidity
FANUC 0i-TF Plus control is the industry standard with broad support

Limitations

16/20 m/min rapids are slower than smaller machines — adds non-cutting time on production runs
11,050 kg requires engineered foundations and significant rigging to install
3,000 RPM max speed limits small-diameter work where higher speeds improve finish
No sub-spindle in the LMA configuration — strictly main-spindle with optional tailstock

Best For

Oil & gas shops turning long shafts, drill pipe, and tubular components Hydraulic cylinder manufacturers needing extended turning length Power generation and industrial equipment makers producing long shaft assemblies Job shops handling large, long parts that don't fit on 8-10 inch chuck lathes Shops needing milling features along the length of long turned parts Production facilities replacing older heavy-duty lathes with modern CNC capability

Frequently Asked Questions

01 What's the difference between the PUMA 4100 LMA, LMB, and LMC?

All three share the same long bed with 2,155 mm Z-travel. The LMA has a 12-inch chuck at 3,000 RPM with 1,024 N-m torque. The LMB steps up to 15-inch at 2,000 RPM with 1,611 N-m. The LMC goes to 21-inch at 1,500 RPM with 2,432 N-m. Choose based on your typical part diameter and material hardness.

02 How does the LMA compare to the standard PUMA 4100 MA?

Same spindle specs and chuck size. The LMA has 2,060 mm turning length versus the MA's 1,010 mm. The LMA is about 1,450 kg heavier. If your parts fit within 1,010 mm, the MA saves floor space and cost. If you need the reach, the LMA is the only option.

03 Can I use a tailstock on the PUMA 4100 LMA?

Yes, a programmable tailstock is a standard option and highly recommended for long shaft work. With over 2 meters of turning length, tailstock support is essential for maintaining dimensional accuracy and preventing deflection on slender parts.

04 What kind of foundation does the 4100 LMA need?

At 11,050 kg, you need a reinforced concrete foundation — typically 8-12 inches of concrete with proper isolation. DN Solutions provides foundation drawings with the machine order. The long footprint means the load is distributed, but the total weight concentration needs engineering review.
