The Nakamura-Tome JX-250 is a high-rigidity multi-tasking turning centre designed for manufacturers machining larger, more complex components with maximum precision and efficiency. Combining turning, milling and simultaneous multi-axis machining within a single platform, the JX-250 reduces setups, shortens cycle times and delivers exceptional accuracy. Equipped with the compact NT Smart Cube tool spindle, twin opposed spindles and an advanced automatic tool changer, the JX-250 provides the flexibility and performance required for demanding production environments.
