Overview
The DN Solutions SMX 2100 is the entry point to DN Solutions' premium multitasking turning platform, and it's a machine that earns the word 'premium.' With an 8-inch chuck, 600 mm (23.6 in) max turning diameter, 1,040 mm (40.9 in) turning length, and a B-axis milling spindle, it handles complex parts that would typically require multiple machines across turning, milling, and drilling departments.
The main spindle delivers 5,000 RPM with 22 kW (29.5 hp) and 467 Nm (344.4 ft-lb) of torque. That's a significant torque upgrade over the DNX 2100 family's 326-456 Nm range, and it shows in the cutting performance. The SMX 2100 takes heavier cuts, pushes bigger tools, and maintains stability at depths that would stress lesser machines. The 600 mm turning diameter versus the DNX's 520 mm gives you room for larger workpieces.
The B-axis milling head is a dedicated spindle (not just live tooling on a turret) with its own motor and independent speed control. This means real milling operations — face milling, thread milling, contouring, and boring — at proper milling speeds and feeds. Combined with the C-axis and Y-axis, you've got a true 5-axis capable multitasking center.
At 14,900 kg (32,849 lb), the SMX 2100 is significantly heavier than the DNX 2100 platform. That mass goes into the base casting, milling spindle support, and guideway construction that let you actually use the machine's capability. The 4,845 x 2,770 mm footprint is wider than the DNX line, reflecting the more substantial milling head and axis configuration.
DN Solutions equips the SMX 2100 with the Fanuc 31i-B5 control (or equivalent high-end Fanuc), which provides the axis count and processing power that true multitasking demands. The SMX 2100 competes with the Mazak Integrex i-200, DMG Mori NTX 2000, and Okuma Multus B250 II in the premium multitasking segment.

Strengths & Limitations
Strengths
- 467 Nm spindle torque is substantially higher than the DNX platform — handles heavy roughing in tough materials
- 600 mm turning diameter accommodates larger workpieces than the DNX 2100's 520 mm limit
- Dedicated B-axis milling head provides real milling capability — not just live tooling on a turret
- 14,900 kg machine weight delivers the rigidity to use the full capability without chatter
- True 5-axis multitasking eliminates multiple machines, setups, and part handling operations
- Fanuc 31i-B5 control provides the processing power and axis count for complex multitasking programs
Limitations
- Base model has no sub-spindle — back-end operations require the S, ST, or SB variants at higher cost
- 4,000 RPM main spindle means limited surface speed on small-diameter high-speed work
- $350,000+ entry price demands serious part volume or complexity to achieve ROI
- Programming complexity requires experienced multitasking operators or dedicated CAM with post processor support
- 14,900 kg weight needs reinforced foundations and careful rigging planning

Frequently Asked Questions
01
Base SMX 2100 machines start around $350,000-$480,000 depending on configuration. Adding a sub-spindle (S variants) pushes the price higher. The full SMX 2100 LST with dual spindles and lower turret can exceed $600,000.
02
Both are premium multitasking platforms with similar capabilities. The SMX 2100 offers slightly more torque and uses a Fanuc control. The Integrex uses Mazak's Mazatrol SmoothAi control with conversational programming. Performance is comparable — the choice usually comes down to control preference, dealer support, and pricing.
03
The B variant steps up to a 10-inch main chuck with 512 Nm torque (vs 8-inch/467 Nm on the standard). It runs at 4,000 RPM instead of 5,000. Choose the B when your parts need a bigger chuck and more torque, the standard when higher speed and smaller parts are the priority.
04
The base SMX 2100 does not include a sub-spindle. The S variant adds a matched sub-spindle, the ST adds a sub-spindle plus lower turret, and the SB adds a big-bore sub-spindle. If you need complete front-and-back part production, you'll need one of these variants.
