PUMA SMX Series

The milling and turning capabilities of the PUMA SMX series allow for fast and precise machining of workpieces in one set-up. The machines in this multi-tasking turning center family are very rigid and employ thermal compensation features that provide constant exceptional performance.

High-Performance Multi-Tasking CNC

The PUMA SMX3100L is engineered for manufacturers who demand precision, flexibility, and throughput in a single setup. With advanced multi-axis capabilities, including B-axis tilting, Y-axis travel, and full contouring C-axis control, this machine enables the machining of highly complex parts without secondary operations. Its integral spindle motor and high-speed automatic tool changer reduce downtime, while thermal growth compensation ensures consistent accuracy during long production runs.

Productivity Through Advanced Automation

Equipped with an 80-tool servo-driven ATC, the SMX3100L delivers rapid 1.8-second tool-to-tool changes, minimizing non-cutting time. The FANUC 31i-B5 control with CUFOS provides powerful 5-axis simultaneous machining and collision protection for safe, efficient workflows. The addition of a programmable servo tailstock and optional steady rests ensures rigidity and support for both slender and heavy shafts, enhancing versatility across industries.

Superior Cutting Power and Accuracy

The machine is built with rigid linear roller guideways, glass scales, and large-diameter double-nut ball screws, giving it exceptional positional accuracy and vibration dampening. With 3,000 rpm turning spindle (40 hp) and 12,000 rpm milling spindle (35 hp), it handles both heavy stock removal and fine surface finishing. Operators benefit from the Tool Center Point Control (TCPC) system, simplifying complex programming while improving cycle times and toolpath efficiency.

Designed for Reliability and Uptime

The PUMA SMX3100L is designed with reliability in mind:

Thermal growth compensation sensors for consistent precision
Automatic tool setter for quick offset calibration
High-capacity coolant system (10 bar standard, 1,000 psi optional) for chip evacuation and tool longevity
Collision Protection System (CPS) integrated into CUFOS for enhanced safety

With a robust construction and integrated automation, this multi-tasking center delivers high accuracy, reduced setup time, and lower cost-per-part, making it ideal for aerospace, energy, and precision component manufacturing.

FAQ Section

What makes the PUMA SMX3100L different from standard mill-turn machines?

Unlike traditional mill-turn centers, the SMX3100L integrates a B-axis tilting milling spindle, Y-axis travel, and full contouring C-axis, enabling complete machining of complex geometries in one setup. This reduces part handling, minimizes errors, and improves throughput. Its FANUC 31i-B5 control with Tool Center Point Control (TCPC) simplifies 5-axis programming and ensures efficient toolpath optimization.

How does the SMX3100L maintain accuracy during long production runs?

The machine incorporates thermal growth compensation sensors, a spindle chiller, and precision glass scales on the X1 axis. These features counteract heat-related expansion, ensuring stable tolerances over extended machining cycles. Its robust spindle bearings and rigid bed design further contribute to long-term repeatability and surface quality.

What industries benefit most from the SMX3100L?

The SMX3100L is designed for industries that require complex, high-precision parts, such as aerospace, energy, oil & gas, defense, and medical device manufacturing. Its ability to handle both heavy-duty roughing and fine finishing in a single setup makes it well-suited for low-volume, high-mix production as well as high-volume manufacturing.

Can the PUMA SMX3100L handle large workpieces?

Yes. The machine supports a maximum turning diameter of 25.98" (660 mm) and a turning length up to 100" (2,540 mm), with a bar capacity of 4.0" (102 mm). Combined with a heavy-duty bed, servo-driven tailstock, and optional steady rests, it can efficiently process both large shafts and intricate multi-axis parts.

How does the machine improve operator productivity?

Operator convenience is prioritized with a swiveling, height-adjustable control panel, quick-access chuck pressure controls, and a large 10.4” ATC operator’s LCD with camera monitoring. Features such as the automatic tool setter and tool load monitoring system reduce setup times, minimize errors, and keep machining operations running smoothly.
