Frequently Asked Questions
Q
What is the key difference between the NXX-26AS and NXX-36AS models?
The NXX-26AS features a 65° slant bed, a max swing diameter of Φ400mm, a spindle bore of Φ36mm, and a total power of 22kW, making it ideal for smaller, high-precision parts. The NXX-36AS offers a 45° slant bed, a larger max swing diameter of Φ500mm, a spindle bore of Φ45mm, and is suited for heavier workpieces up to Φ450mm in diameter.
Q
What is the advantage of the synchronized twin-spindle and dual-gang-tooling design?
The synchronized twin-spindle system allows dynamic part hand-off between the main and sub-spindles, enabling complete multi-surface machining in a single setup. This eliminates the need for re-fixturing, significantly reducing geometric tolerances and improving overall part consistency and production efficiency.
Q
What positioning accuracy and repeatability can these machines achieve?
Both the NXX-26AS and NXX-36AS achieve a repeatability of ±0.0025mm on all axes (X1/X2 and Z1/Z2). The spindle runout accuracy is ≤0.003mm, and the main/sub-spindle coaxiality for synchronization is ≤0.01mm, ensuring micron-level precision throughout the machining process.
Q
How does the T-Type Gang Tooling system benefit production throughput?
The T-style gang tool post supports versatile multi-tool configurations with a maximum capacity of 16 tools per setup. Its unique design enables rapid and seamless tool indexing, minimizing idle time between operations and maximizing overall machining throughput for high-volume production environments.
Q
What measures are in place to ensure thermal stability and long-term accuracy?
The machine employs a direct-drive axis configuration with pre-tensioned precision ball screws and an automatic lubrication system to minimize thermal displacement. The hydraulic system is equipped with premium Taiwanese variable pumps and an integrated air cooler, ensuring optimal oil temperature stability during extended machining cycles.
