TRAUB TNA 400 HORIZONTAL MACHINING CENTER

The TRAUB TNA 400 is a high-precision horizontal machining center designed for versatile turning applications. It features a main spindle capable of machining up to a 15.55" diameter and 29.53" length, with a maximum spindle bar diameter of 2.56". The spindle operates at speeds up to 4,000 RPM, delivering 29.5 HP of power, suitable for medium to large series production. The machine includes a primary turret tool carrier with 12 tool positions, all capable of rotary operation, powered by 7.4 HP motors reaching 4,000 RPM. It supports simultaneous cutting with a single tool across 2 axes, offering axial travels of 8.86" (X-axis), 29.57" (Z-axis), and a maximum feed rate and rapid traverse of 590 inches per minute on both X and Z axes, ensuring fast and accurate material removal. The machine’s robust design includes rigid mineral cast bed construction for enhanced stability and vibration damping. Its work area facilitates excellent accessibility for setups and chip evacuation, optimized for long boring bars and efficient tool changes. The TRAUB TNA 400 integrates advanced control with a turret capable of precision indexing, supporting live tools and high-speed machining. The unit’s configuration allows precise machining of complex parts with stable spindle torque and high feed rates, making it ideal for tooling, prototyping, and serial production environments. Its combination of spindle power, tool flexibility, and axis travel makes it a reliable solution for precision horizontal turning tasks.
