Built for Complex Machining in a Single Setup

The DN Solutions PUMA SMX2600ST is a high-performance 5-axis mill-turn center designed to handle the most complex components with unmatched precision and efficiency. Combining upper B-axis milling, twin spindles, and a lower turret, this multitasking platform offers complete front- and back-side machining of intricate parts—from bar to finished product—in one seamless cycle. Its ±120° B-axis tilt and synchronized spindles allow angular milling, compound contouring, and full 6-sided machining, making it ideal for aerospace, energy, and medical applications requiring tight tolerances and part consistency.

Dual Spindles and B-Axis Milling for Ultimate Flexibility

At the heart of the SMX2600ST is a powerful 12,000 rpm milling spindle with HSK-T63 taper and 22 kW (29.5 hp) output, capable of interpolated 5-axis machining using the ±120° B-axis rotation. The main spindle delivers 5,000 rpm with a 3.1" bar capacity and 30 hp cutting power, while the sub-spindle offers 6,000 rpm and 20.1 hp for high-speed part transfer and backworking. These systems work in tandem to enable complex machining strategies like pinch turning, multi-angle drilling, and simultaneous OD/ID operations—significantly reducing part cycle time and improving throughput.

Lower Turret for Simultaneous and Balanced Cutting

The 10-station lower turret brings an extra axis of productivity, enabling dual cutting paths with the upper head for operations like roughing and finishing in parallel. It supports live tools and is servo-driven for accurate positioning. This turret enhances part complexity handling and reduces idle time by allowing operations on both spindles concurrently. Ideal for operations like grooving, threading, or drilling on secondary surfaces, the lower turret makes the SMX2600ST an elite multitasking center with true parallel processing capability.

Thermal Stability, Structural Integrity, and Automation Ready

The SMX2600ST is built on a robust slant-bed Meehanite® casting with symmetric column structure, designed to resist thermal deformation and vibration during heavy cuts. Preloaded LM roller guideways and dual-anchored ball screws ensure rigidity and high-speed accuracy across all axes. The machine features integrated tool probing, disturbance torque monitoring, and thermal compensation systems to maximize uptime and tool life. With a standard 40-tool magazine (expandable to 120), high-pressure coolant options, and part catcher/robot interfaces, it's ready for full automation in high-mix, high-volume environments.

Smart Control and Operator-Friendly Interface

The machine is powered by the FANUC 31i-B5 control with 19″ iHMi touchscreen, delivering high-speed 5-axis processing and intuitive navigation. The standard CUFOS (Customized Flexible Operation Solution) suite includes digital twin simulation, in-process monitoring, and conversational cycle generation. With EZ Guide i onboard, operators can program turning, milling, and drilling cycles on the shop floor without writing G-code. These control enhancements reduce setup times and training curves, empowering shops to get the most from the SMX2600ST’s capabilities.

FAQ Section

Who is the SMX2600ST best suited for?

This machine is ideal for manufacturers needing to produce complex parts in aerospace, defense, medical, or energy sectors. It shines in applications where multiple angled cuts, compound surfaces, and back-side features are required—such as turbine blades, orthopedic implants, or valve housings.

Can the SMX2600ST run lights-out or unattended?

Yes. The machine supports robotic part handling, bar feeding, automatic tool probing, and monitoring systems like disturbance torque detection and thermal compensation—making it highly reliable for unmanned or overnight operations.

What’s the difference between the SMX2100ST and SMX2600ST?

While both offer multitasking capabilities, the SMX2600ST offers larger workpiece capacity (29.5″ diameter vs. 20.1″), more power (30 hp vs. 22 hp spindle), and greater part length support (59.1″). It's designed for heavier-duty applications and larger parts.

Does the B-axis head allow true 5-axis machining?

Yes. The ±120° B-axis milling spindle enables simultaneous 5-axis contouring and positional machining. This allows the SMX2600ST to perform advanced operations like impeller milling, angled hole drilling, and multi-surface contouring with full accuracy.

What software comes standard with this machine?

The SMX2600ST includes FANUC 31i-B5 control with DN Solutions’ CUFOS platform, EZ Guide i conversational software, and full digital twin simulation. These tools help reduce programming complexity and increase operator confidence.
