Overview
The DN Solutions PUMA 2100 SY II is the full-featured variant in the 2100 Y-axis turning center lineup, combining a Y-axis, sub-spindle, and live tooling on an 8-inch chuck platform. The S stands for sub-spindle and the Y for Y-axis milling — together they give you done-in-one capability for complex parts that need turning, off-center milling, and backworking in a single setup. If you are running parts with features on both ends and cross-drilled or milled geometry, this is the machine that eliminates your second and third ops.
The main spindle delivers 22 kW (29 hp) with 358 Nm (264 ft-lb) of torque at up to 5,000 RPM. That is a step up from the older DNT 2100 M series in both speed and power, reflecting the newer PUMA II generation platform. The sub-spindle runs at 6,000 RPM with 15 kW (20 hp), giving you serious capability for backworking operations — not just parting off, but full turning, drilling, and finishing on the B-side.
Max turning diameter is 406 mm (16 in) with 520 mm (20.5 in) of turning length. The Y-axis provides 105 mm (4.1 in) of travel for off-center milling — enough for flats, slots, and eccentric features that would otherwise require a separate VMC setup. X-axis runs 260 mm (10.2 in) and Z-axis gives you 590 mm (23.2 in). All rapids hit 30 m/min on both X and Z axes.
The 12-station turret drives live tools at 5,000 RPM. Combined with the Y-axis and C-axis, you can mill pockets, drill off-center holes, cut keyways, and engrave — true mill-turn capability on a turning platform. The FANUC 0i-TF Plus control handles the multi-axis coordination smoothly.
At 5,550 kg (12,236 lb), the SY II carries more mass than the base DNT 2100 models due to the sub-spindle assembly and Y-axis mechanism. The footprint is 3,190 mm (126 in) long by 1,945 mm (77 in) wide. For shops producing complex parts that currently require two or three setups across a lathe and mill, the PUMA 2100 SY II consolidates everything into one machine and one program.

Strengths & Limitations
Strengths
- Full done-in-one capability with Y-axis, sub-spindle, and live tooling eliminates second and third ops
- 22 kW main spindle at 5,000 RPM provides excellent speed for aluminum and steel in the 8-inch chuck class
- 6,000 RPM sub-spindle with 15 kW is powerful enough for real backworking, not just parting off
- 105 mm Y-axis travel handles flats, slots, keyways, and eccentric features without a separate VMC
- 30 m/min rapids on both axes keep non-cutting time low in high-volume production
- 406 mm max turning diameter is generous for an 8-inch chuck machine
Limitations
- Sub-spindle and Y-axis add significant cost over the base 2100 Y II or DNT 2100 M
- 520 mm max turning length is short — longer parts need the LSY II variant
- 5,550 kg weight requires more floor prep than simpler 2-axis lathes
- 358 Nm torque is adequate but not exceptional for heavy roughing in tough materials

Frequently Asked Questions
01
The SY II adds a sub-spindle (6,000 RPM, 15 kW) for backworking operations. The Y II has the Y-axis and live tooling but no sub-spindle, so parts need to be manually rechucked for B-side work. If your parts have features on both ends, the SY II eliminates that handling.
02
The 2100 SY II is a different class of machine. It adds Y-axis (105 mm travel), sub-spindle (6,000 RPM), and runs the main spindle at 5,000 RPM versus 4,500 on the DNT. It is significantly more capable for complex parts but costs $40,000-$60,000 more.
03
Yes, bar feeder integration is a standard option. The 8-inch chuck accommodates common bar stock sizes. Combined with the sub-spindle for backworking and automatic part transfer, this is an excellent lights-out bar production machine.
04
With 105 mm of Y-axis travel and 5,000 RPM live tools, you can mill flats, cut slots and keyways, drill off-center holes, and create eccentric features. Combined with C-axis interpolation, it handles most secondary milling operations that would otherwise require a VMC.
