Unleashing Complex Part Production with the SMX3100ST Multi-Axis Mill Turn Center

The PUMA SMX3100ST stands as a pinnacle of multi-axis machining technology, meticulously engineered to address the most demanding challenges in modern manufacturing. As a high-performance multi-axis mill turn machine, it seamlessly integrates advanced milling and turning capabilities within a single, robust platform, revolutionizing how complex workpieces are produced. This innovative design, featuring a total of nine axes, empowers engineers to execute intricate geometries and achieve superior surface finishes with unparalleled flexibility and precision. 

By combining multiple operations into one setup, the SMX3100ST significantly reduces cycle times, minimizes non-cutting periods through fast rapid traverse rates, and ensures long-term high accuracy, making it an indispensable asset for industries prioritizing efficiency and quality. This strategic consolidation of processes directly translates into substantial buyer benefits, including reduced lead times, decreased changeover times, and optimized setup durations, aligning perfectly with just-in-time production requirements.

Precision Engineering and Advanced Control Systems for Unrivaled Performance

The engineering excellence of the SMX3100ST is evidenced by its exceptional precision and stability, crucial for heavy and interrupted cutting operations. At its core, the machine features a FANUC 31i-B5 with CUFOS dual path 5-axis simultaneous control, providing comprehensive command over its sophisticated kinematics, including C-axis contouring, Y-axis off-center machining, and B-axis any-angle milling/drilling capabilities. This advanced control system is complemented by a robust, one-piece, heavily ribbed casting bed and heavy-duty linear roller guideways that inherently inhibit thermal deformation and twisting while providing excellent vibration dampening. 

Further enhancing precision, the X1-Axis incorporates linear glass scales, effectively nullifying the impact of thermal expansion on slides and ball screws, thus ensuring tighter part tolerances with fewer offset adjustments. Integral motors on both the left and right spindles, alongside a 12,000 rpm milling spindle, deliver high torque for aggressive material removal and pristine finishes, all while maintaining precise thermal control via spindle chillers.

Operational Efficiency, Automation, and Long-Term Reliability

Designed for sustained productivity and minimal operator intervention, the SMX3100ST integrates a suite of automation and reliability features that underscore its value proposition for B2B manufacturing. An automated part unloading system, complete with a part ejector, coolant flush, part catcher, and conveyor, facilitates unattended operation, particularly when coupled with a bar feeder. 

Tool changes are rapid, with an 80-station Automatic Tool Changer (ATC) delivering a mere 1.8-second tool-to-tool change time. Durability is built-in, with large-diameter double-nut ball screws protected by an unexpected disturbance torque detection system featuring an "airbag function" to minimize crash damage and downtime. 

The machine’s advanced cooling system boasts multi-stage pumps, providing 10 bar (145 psi) for the milling spindle and 4.5 bar (65 psi) for the lower turret, ensuring optimal chip evacuation and extended tool life, with an optional 1000 PSI coolant system available for even more demanding applications. 

Furthermore, eco-friendly grease lubrication for guideways and ball screws reduces maintenance and operating costs, while a comprehensive two-year machine parts and control warranty demonstrates the manufacturer's confidence in its enduring performance. The SMX3100ST is ideal for critical applications across the aerospace, automotive, and energy sectors, handling everything from intricate parts to the largest and most complex components.
