Overview

The DN Solutions PUMA 2100 LY II pairs Y-axis milling and live tooling with the PUMA 2100 II's box-way construction on a long-bed platform, without the cost of a sub-spindle. The designation breaks down as L (long bed), Y (Y-axis), II (second generation). For shops that need the rigidity and vibration damping of box-way construction with Y-axis milling capability, but don't require backworking, this is the value proposition.

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. Max turning diameter is 340 mm (13.4 in) with 540 mm (21.3 in) of turning length on the long-bed platform. The box-way construction provides superior cutting stability compared to linear guide machines, especially on interrupted cuts in cast iron and forgings.

The Y-axis provides ±52.5 mm (±2.07 in) of off-center travel for true milling of flats, hexagons, keyways, and off-center features. The 12-station turret runs live tools at 6,000 RPM. 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.

At approximately 4,200 kg (9,259 lb), the PUMA 2100 LY II is lighter than the LSY II variant (no sub-spindle weight) but retains all the box-way rigidity that makes the PUMA platform a step above the LYNX series. It's positioned for shops that want PUMA-class cutting performance with Y-axis milling at a price point $30-40K below the full LSY II configuration. Parts that only need one-end machining but demand superior surface finish and tight tolerances in tough materials are the sweet spot. 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 + live tooling enables true off-center milling at a lower cost than the sub-spindle LSY II
318 Nm torque with box-way damping delivers excellent surface finish on tough materials
Larger work envelope than LYNX 2100: 340 mm turning diameter and 540 mm turning length
$30-40K savings over the LSY II when sub-spindle isn't needed
PUMA-class durability for 24/7 production environments

Limitations

No sub-spindle — backside operations require a second setup on another machine
24/30 m/min rapids are slower than linear guide machines due to box-way construction
4,200 kg weight requires more substantial floor preparation than comparable LYNX variants
±52.5 mm Y-axis travel is the same as lighter machines in the lineup

Best For

Shops cutting tough materials where box-way rigidity provides measurably better finish and tool life Production of parts with off-center features that only need one-end machining Aerospace and defense manufacturers with tight tolerance requirements on hard alloys Shops wanting PUMA-class rigidity with Y-axis at a lower price than the full LSY II Facilities upgrading from older box-way lathes that want to add Y-axis capability

Frequently Asked Questions

01 What's the difference between the LY II and the LSY II?

The LSY II adds a sub-spindle for machining both ends of the part in one cycle. The LY II has the same box-way construction, Y-axis, and live tooling but no sub-spindle. Choose the LY II when parts only need one-end machining and save $30-40K.

02 Why choose the PUMA 2100 LY II over the LYNX 2100 LYB?

The PUMA uses box-way construction while the LYNX uses linear guides. Box ways provide better vibration damping, more rigidity on interrupted cuts, and longer machine life under heavy use. The PUMA also has a larger work envelope. Choose the LYNX for speed and value; the PUMA for heavy cutting and durability.

03 How does box-way construction affect cycle times?

Box ways have slightly slower rapids (24/30 m/min vs 30/36 m/min on linear guides) due to higher friction. On short-cycle parts with lots of rapid moves, the LYNX is faster. On longer-cycle parts with significant cutting time, the PUMA's ability to take heavier cuts often reduces overall cycle time despite slower rapids.

04 Is the PUMA 2100 LY II suitable for bar-fed production?

Yes. With a bar feeder and parts catcher, it runs unattended production. The only limitation vs the LSY II is that parts drop out after main-spindle machining without backside work. For parts that don't need backworking, the LY II is an excellent bar-fed production machine.
