Case Study: Alstom Boosted Bogie Production with a Custom SORALUCE Bridge Mill

When Alstom, a global leader in railway transportation technology, needed to streamline production for two different types of bogie frames, they turned to a trusted partner in multitasking innovation—SORALUCE. The result? A highly customized PM40 Bridge-Type Multitasking Machine that delivers tight tolerances, 24/7 uptime, and operational efficiency above 90%. Here’s how this advanced solution is helping Alstom set new standards in bogie machining.

Meeting Demands of a Global Rail Leader

Alstom required a solution flexible enough to handle different bogie designs while maintaining extreme accuracy across large parts. With operations running non-stop and tolerances as tight as 2 µm over nearly 1.7 meters, the project demanded not only power, but precision engineering and reliable automation.

Custom-Engineered PM40 Bridge Mill

The PM40 Bridge-Type Multitasking Machine was configured specifically to handle the size, complexity, and flexibility Alstom required. Key machine specs include:

• 196" X-axis, 177" Y-axis, and 78" Z-axis travel

• Two massive 157" x 118" tables

• Automatic Head Changer with 5 positions

• Robot Tool Arena with a 395-tool capacity

This configuration enables seamless handling of large parts and complex geometries without constant tool change delays or manual intervention.

Automatic Head Changer & Custom Angular Heads

The machine’s automatic head changer offers five head positions for seamless angle changes. With custom angular heads, Alstom gets the reach and precision to nail every detail of bogie geometry.

Digital Enhancements: DAS+ & Adaptive Control

Equipped with DAS+ (Dynamic Active Stabilizer) and Adaptive Control technology, the machine dynamically compensates for vibration and cutting conditions in real-time. These smart controls enhance tool life, improve surface finish, and maintain dimensional accuracy on every part.

Production Uptime & Efficiency Beyond 90%

Thanks to the dual-table setup and robust multitasking design, Alstom runs the PM40 machine 24/7 with an overall equipment effectiveness (OEE) greater than 90%. The machine’s ability to switch between bogie types without lengthy setup changes minimizes idle time and maximizes throughput.

The SORALUCE PM40 proves what’s possible with the right multitasking solution, reach out to Morris and Select Machining Technologies to learn more.
