Overview
The DN Solutions PUMA 700 LM II is a large-bore, heavy-duty horizontal turning center that steps well beyond the PUMA 5100 series into true big-iron territory. With a 24-inch chuck, 900 mm (35 in) max turning diameter, and 3,200 mm (126 in) of turning length, this machine handles workpieces that would overflow anything in the 4100 or 5100 range.
The spindle is a monster: 55 kW (74 hp) pushing 8,076 Nm (5,957 ft-lb) of torque through a 375 mm (14.8 in) bore. That through-bore is big enough to pass large-diameter tubular stock without a bar feeder. The spindle tops at 1,500 RPM, which delivers excellent surface speed on the large-diameter work this machine is designed for.
What sets the LM II apart from the base 700 M II is the long bed. Z-axis travel reaches 3,235 mm (127 in), compared to 1,650 mm on the standard-bed variant. The L designation also adds a Y-axis with 200 mm (8 in) of travel for off-center milling, making this a true mill-turn machine for large parts. The 12-station turret runs live tools at 3,000 RPM.
Axis rapids are 12 m/min on X and 10 m/min on Z — slow compared to smaller machines, but moving 22,000 kg (48,502 lb) of iron accurately requires controlled motion. The box-way construction is heavy-duty throughout, designed for decades of production abuse on the toughest materials.
The FANUC 0i-TF Plus control handles the programming and machine control. At this machine class, most shops are running G-code with custom macros, and the FANUC platform supports that workflow well. The PUMA 700 LM II represents a serious capital investment, but for shops in power generation, oil and gas, marine, and heavy industry, it's the kind of machine that defines their capability.

Strengths & Limitations
Strengths
- 8,076 Nm (5,957 ft-lb) of torque is immense — handles the heaviest roughing passes in any material
- 375 mm (14.8 in) spindle bore passes large-diameter tubular stock and hollow workpieces
- 24-inch chuck with 35-inch swing covers workpieces far beyond the capability of 5100-class machines
- Y-axis with 200 mm travel enables off-center milling on large parts without secondary setups
- 3,200 mm max turning length handles long shafts, rollers, and tubular components
- 22,000 kg machine mass provides exceptional thermal stability and vibration absorption
Limitations
- 10 m/min Z-axis rapids are slow — expect long non-cutting traverse times on long parts
- 22,000 kg requires heavy industrial foundations and specialized rigging for installation
- 7.3 meter machine length demands a large dedicated floor space
- High capital cost limits this machine to shops with consistent large-part volume to justify the investment
- 3,000 RPM max live tool speed is lower than smaller PUMA machines (4,000-6,000 RPM)

Frequently Asked Questions
01
The LM II has the long bed — 3,235 mm Z-axis travel versus 1,650 mm on the M II. Max turning length is 3,200 mm vs 1,600 mm. Both have the same spindle, chuck, Y-axis, and live tooling. Choose the LM II for long parts; the M II saves floor space and cost for shorter chucking work.
02
The large bore lets you pass tubular workpieces through the spindle for pipe and casing work. It also allows larger-diameter bar stock to be fed through for long production runs. In oil and gas applications, this bore size is especially valuable for machining pipe fittings and couplings.
03
The 200 mm Y-axis travel with 3,000 RPM live tooling allows off-center drilling, tapping, milling flats, cutting keyways, and machining bolt hole patterns. Combined with C-axis interpolation, you can produce complex mill-turn features on large parts without moving them to a separate VMC.
04
At 22,000 kg, you'll need a reinforced concrete foundation typically 400-500 mm thick with vibration isolation if other precision machines are nearby. DN Solutions provides detailed foundation drawings and specifications. A structural engineer should review the installation site before delivery.
05
Plan for 2-3 weeks from rigging-in to production. That includes positioning, leveling, electrical hookup, hydraulic fill, geometric alignment verification, and test cutting. The long bed requires especially careful leveling to maintain accuracy across the full travel. Most dealers handle the full installation and commissioning.
