STARRAG BUMOTEC S191 CNC LATHE

Technical Description

The Fanuc 31i-B5 CNC Control is a high-performance system designed for complex multi-axis machining applications. It features a **Fanuc 31i-B5 control platform** capable of managing up to **96 axes and 24 spindle axes with simultaneous 5-axis machining**, supporting enhanced precision and high-speed operation. The machine parameters include an X-axis travel of **16.14 inches** and Z-axis travel of **15.75 inches**, with a **distance between centers of 18 inches**. The spindle assembly includes a primary spindle bore of **1.90 inches**, a spindle speed up to **30,000 RPM** driven by a **30 HP motor**, and a secondary spindle capable of **60,000 RPM** with a bar capacity of **1.25 inches** on both spindles. The system provides **60 tool positions** and supports B-axis rotation with a travel range of **+115 to -25 degrees**, enabling complex 5-axis tool orientations. Advanced features of the CNC include digital servo control, high-resolution position inputs down to 0.001mm or 0.0001", and AI contour control for smooth and precise toolpath execution. The controller offers multiple programmable axes and spindle controls with robust interpolation capabilities and supports preventive maintenance functions to maximize uptime. Additional functionalities, such as high-speed smooth TCP, collision avoidance, and adaptive feed control, enhance machining efficiency and quality. The system supports versatile programming languages including EIA/ISO, and advanced 3D tool compensation and monitoring features, making it suitable for demanding milling, turning, and mill-turn applications requiring precision and high productivity. This controller is optimized for complex parts with accelerated cycle times and superior surface finishes.
