Overview
The DN Solutions PUMA 2100 LSY II is the full-capability variant of the PUMA 2100 II series, combining a long bed, sub-spindle, and Y-axis with box-way construction for maximum rigidity. The designation breaks down as L (long bed), S (sub-spindle), Y (Y-axis), II (second generation). This is DN Solutions' premium small-to-mid-size turning platform for complex done-in-one parts that demand both heavy cutting authority and precise milling capability.
The main spindle delivers 18.5 kW (25 hp) at 4,500 RPM with 318 Nm (235 ft-lb) of torque through an 8-inch (210 mm) chuck. That's PUMA-class box-way rigidity paired with mill-turn versatility. Max turning diameter is 340 mm (13.4 in) with a generous 540 mm (21.3 in) of turning length on the long-bed platform. The 12-station turret runs live tools at 6,000 RPM.
The Y-axis provides ±52.5 mm (±2.07 in) of off-center travel for true milling of flats, hexagons, keyways, and off-center holes. The sub-spindle picks up parts after main-spindle operations for backside machining, delivering complete parts from bar stock. Axis travels span 230 mm (9 in) on X, ±52.5 mm on Y, and 620 mm (24.4 in) on Z, with rapid traverse at 24/10/30 m/min.
The key advantage of the PUMA 2100 LSY II over the LYNX 2100 LSYA/LSYB is construction. Box ways absorb vibration and provide damping that linear guide machines can't match, especially during heavy interrupted cuts. If you're running cast iron, forgings, or tough alloys where chatter is a concern, the PUMA's box-way construction delivers noticeably better surface finish and tool life. At approximately 4,500 kg (9,921 lb), it's heavier than the LYNX but that mass translates directly to cutting stability. FANUC 0i-TF Plus control is standard.

Strengths & Limitations
Strengths
- Box-way construction provides superior vibration damping and rigidity vs linear guide competitors
- Y-axis + sub-spindle + live tooling for complete done-in-one processing of complex parts
- 318 Nm torque with 8-inch chuck handles aggressive roughing in tough materials with minimal chatter
- Larger work envelope than LYNX 2100: 340 mm turning diameter and 540 mm turning length
- PUMA-class rigidity translates to better surface finish and longer tool life on interrupted cuts
- 6,000 RPM live tooling provides versatile secondary milling capability on both spindles
Limitations
- 24/30 m/min rapids are slower than the LYNX 2100's 30/36 m/min due to box-way construction
- 4,500 kg weight and 3,200 mm length require more floor space than comparable LYNX variants
- Price premium of $25-40K over the LYNX 2100 LSYB for box-way construction
- ±52.5 mm Y-axis travel is the same as lighter LYNX variants — no increase with the heavier platform

Frequently Asked Questions
01
The PUMA uses box-way construction while the LYNX uses linear guides. Box ways provide better vibration damping, superior rigidity on interrupted cuts, and longer machine life under heavy use. The PUMA also has a larger work envelope (340 mm vs 300 mm turning diameter). Choose the PUMA for heavy cutting; the LYNX for speed and value.
02
The 'II' indicates the second generation of the PUMA 2100 platform. Gen II machines feature improved thermal stability, updated casting designs, and the latest FANUC 0i-TF Plus control with iHMI touchscreen interface.
03
The PUMA 2100 II and DNT 2100 are closely related platforms. The 2100 LSY II specifically adds Y-axis and sub-spindle to the long-bed configuration. The DNT 2100 series offers various combinations (M, MB, etc.) but the LSY II is the full-featured variant with all capability options.
04
Yes. With a bar feeder, parts catcher, chip conveyor, and coolant management, it runs unattended production of complete parts. The sub-spindle handles part transfer, and the Y-axis enables all milling features. The box-way construction provides the long-term reliability needed for extended unattended runs.
