Overview
The DN Solutions DNX 2100 is a compact multi-tasking turning center that bridges the gap between a standard Y-axis lathe and a full B-axis multi-tasking machine. Where the SMX series adds a B-axis milling head for full angular machining, the DNX 2100 takes a more practical approach — it combines a powerful turning spindle with Y-axis capability and a BMT live tooling turret, giving shops genuine multi-tasking productivity without the programming complexity and price premium of B-axis machines.
The main spindle delivers 22 kW (30 hp) at 4,000 RPM through an 8-inch chuck, with 573 Nm (423 ft-lbs) of torque. The 12-station BMT turret provides live tooling at 6,000 RPM with 5.5 kW (7.4 hp), and the Y-axis extends +/- 52.5 mm (105 mm total travel) for off-center drilling, milling, and tapping. A sub spindle running at 5,000 RPM with 15 kW (20 hp) enables back-working for complete done-in-one processing.
Axis travels span 260 mm on X, 105 mm on Y (+/- 52.5 mm), and 620 mm on Z, with 350 mm (13.8 in) max turning diameter and 570 mm (22.4 in) max turning length. Bar capacity is 65 mm (2.6 in) through the main spindle. Rapid traverse rates of 30 m/min on X and 36 m/min on Z keep cycle times tight.
The DNX 2100 runs on a FANUC 0i-TF Plus control — simpler and more familiar than the 31i-B5 used on SMX machines, which is an advantage for shops transitioning from standard turning. At roughly 6,500 kg (14,330 lb), it has a much smaller footprint than SMX machines and fits into existing turning cell layouts. New machines price between $180,000 and $280,000, making it one of the most cost-effective entry points into multi-tasking with Y-axis and sub-spindle capability.

Strengths & Limitations
Strengths
- Compact multi-tasking capability with Y-axis, sub spindle, and BMT live tooling provides done-in-one processing at a fraction of the cost and complexity of B-axis machines
- FANUC 0i-TF Plus control is simpler and more familiar than the 31i-B5 on SMX machines, making it an easier transition for shops upgrading from standard turning centers
- 6,500 kg machine weight and compact footprint fits into existing turning cell layouts without the foundation work and floor space demands of larger multi-tasking machines
- BMT turret with 6,000 RPM live tooling at 5.5 kW delivers genuine milling capability for hex flats, cross-holes, keyways, and other features that would otherwise require a second operation
- Sub spindle with 5,000 RPM and 15 kW enables complete back-working including turning, drilling, and live tooling operations on the second side
Limitations
- No B-axis milling head means angular machining is limited to what the turret-mounted live tools can reach — complex compound-angle features still need a machining center
- 105 mm Y-axis travel is modest compared to larger mill-turn machines, limiting the size and position of off-center milled features
- 350 mm max turning diameter and 570 mm turning length constrain part size — shops with larger work need the PUMA 2600SY or SMX series
- 12-station turret limits tool capacity for complex parts compared to the 60-80 tool ATCs on SMX machines

Frequently Asked Questions
01
New DNX 2100 machines typically price between $180,000 and $280,000 depending on configuration. Base machines with Y-axis and live tooling start around $180K; adding the sub spindle and full options package pushes toward $280K. That's roughly half the price of an SMX 2600, making it one of the most accessible multi-tasking turning centers on the market.
02
The DNX 2100 is essentially an evolution of the PUMA 2100SY platform with updated design and kinematics optimized for multi-tasking. The key differences are in the turret and live tooling performance — the DNX series features upgraded BMT tooling with higher rigidity and speed. Both share similar work envelopes and spindle specs, but the DNX represents the current-generation platform.
03
For many small to medium parts under 350 mm diameter, yes. The Y-axis and BMT live tooling handle hex flats, cross-holes, keyways, off-center drilling, and light milling. The sub spindle completes back-side features. The limitation is parts with complex angular milling or large milled pockets — those still benefit from a dedicated machining center or B-axis mill-turn like the SMX series.
04
The 65 mm bar capacity works with standard magazine and hydrodynamic bar feeders from LNS, IEMCA, FMB, and Edge Technologies. Most shops pair it with a 6-foot or 12-foot magazine feeder for unattended production. The FANUC control supports standard bar feeder interface protocols for automated bar change and remnant management.
