One Machine. Complete Machining. Infinite Flexibility.

The PUMA SMX2100ST is DN Solutions' flagship multitasking platform, engineered for complete part machining—from raw bar to finished component—in one cycle. Built on a one-piece slant bed casting with a symmetric column design, this compact mill-turn center integrates a 12,000 rpm B-axis milling spindle, left and right turning spindles, and a lower turret for simultaneous multi-surface machining. With dual tool changers and Y+B-axis movement, the SMX2100ST eliminates setup delays and enables true 5-axis contouring and positional work. Whether tackling impellers, orthopedic implants, aerospace blisks, or multi-step hydraulic housings, this machine excels at precision-driven complexity.

5-Axis Power with B-Axis Milling Spindle and Twin Spindles

At the heart of the machine is a high-speed 12,000 rpm B-axis milling spindle delivering 22 kW (29.5 hp) of cutting power. Its B-axis swings ±120°, allowing access to virtually any angle without reclamping. The left and right turning spindles (5,000 rpm and 6,000 rpm, respectively) allow for synchronized part handoff and full front/back machining. These are paired with a lower turret that can operate independently or simultaneously with the milling spindle for balanced or pinch turning. This hybrid architecture allows users to mill, turn, drill, tap, and perform Y/B-axis interpolation—all within a single machine cycle.

Lower Turret with Servo-Driven BMT Tooling

The 10-station lower turret on the SMX2100ST adds another level of flexibility by enabling simultaneous OD/ID turning or independent milling using live tools (optional). Each station supports rigid tapping, and the turret’s positioning accuracy ensures tight tolerances during balanced cutting. In multi-tasking environments, the lower turret significantly reduces cycle times by allowing parallel machining—such as rough turning with the turret while finish-milling with the upper head. This layered approach maximizes throughput and tool engagement while minimizing idle time.

Advanced Automation, Intelligence, and Thermal Stability

Automation and reliability are cornerstones of the SMX2100ST. The tool magazine offers 40 stations standard (up to 120 optional), and tool probing comes standard for fast setup and wear detection. The symmetric column design reduces thermal distortion, while the roller-type LM guideways and precision ball screws ensure high-speed positioning and repeatability. Disturbance torque detection and thermal compensation help protect tooling and spindles during continuous use. For long-run unattended operation, the machine integrates seamlessly with bar feeders, part catchers, robotic cells, and chip management systems.

Intuitive Operation via FANUC 31i-B5 + CUFOS

Operators interface with the FANUC 31i-B5 CNC and a 19″ touchscreen iHMi, delivering high-speed processing, 5-axis control, and intelligent diagnostics. The system includes DN Solutions' CUFOS (Customized Flexible Operation Solution)—a suite of features for digital part simulation, conversational programming, and in-cycle monitoring. EZ Guide i software also supports simplified cycle generation with graphical prompts. This intelligent control ecosystem ensures machinists of all skill levels can maximize the machine’s potential without writing complex G-code.

FAQ Section

What makes the SMX2100ST different from a regular CNC lathe?

Unlike traditional lathes, the SMX2100ST combines full turning, milling, and 5-axis capability in a single machine. It has a B-axis milling spindle, dual turning spindles, and a lower turret—all enabling complete part production without additional setups or machines.

Can the SMX2100ST perform simultaneous multi-axis machining?

Yes. The machine allows for simultaneous operation of the upper spindle head and the lower turret. You can rough-turn with the turret while finish-milling with the B-axis head, or perform dual-side machining using both spindles—greatly reducing cycle times.

What types of parts are best suited for this machine?

The SMX2100ST excels at complex, multi-featured parts like impellers, orthopedic implants, aerospace components, energy couplings, or any component requiring angular milling, back-side machining, or tight feature-to-feature tolerance in one setup.

How does the CUFOS system improve operator productivity?

CUFOS includes a suite of control-side enhancements like digital part simulation, on-screen monitoring, and conversational programming tools. It lowers the skill barrier for operators while improving setup speed and in-process awareness.

Is the SMX2100ST a good candidate for lights-out machining?

Absolutely. With built-in tool probing, thermal compensation, disturbance detection, and optional automation integrations (robots, conveyors, part catchers), this machine is ideal for unattended, high-precision, long-run applications.
