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 angle, a spindle bore of Φ36mm, max bar capacity of Φ25mm, and a total power capacity of 22 kW, while the NXX-36AS has a 45° slant bed, a larger spindle bore of Φ45mm, max bar capacity of Φ35mm, and a total power of 18 kW. The NXX-36AS also offers a greater max turning length of 200mm and a higher machine weight of 4,600 kg.
Q What type of tooling system does this CNC lathe use?
Both models use a T-Type Gang Tooling system (gang-type tool post) that supports up to 16 tools. The unique T-style gang tool post enables versatile multi-tool configurations and rapid, seamless tool indexing for maximized machining throughput.
Q How does the synchronized twin-spindle system benefit production?
The synchronized twin-spindle and dual gang tool post configuration allows dynamic part hand-off (re-gripping) between the main and sub-spindles. This enables complete multi-surface machining in a single setup, significantly reducing geometric tolerances, minimizing part handling, and ensuring superior consistency across production runs.
Q What positioning accuracy and repeatability can be expected?
Both models achieve a spindle runout accuracy of ≤0.003 mm and axis repeatability of ±0.0025 mm on both X and Z axes. The main/sub-spindle coaxiality for synchronization is ≤0.01 mm, making these machines suitable for high-precision machining applications.
Q What measures are taken to ensure thermal stability and long-term accuracy?
Each axis uses pre-tensioned precision ball screws with a direct-drive servo motor configuration, combined with high-rigidity linear guideways and an automatic lubrication system to minimize thermal displacement. The hydraulic system is equipped with an integrated air cooler using premium Taiwanese variable pumps and solenoid valves to maintain optimal oil temperature during prolonged machining cycles.
Q Is this machine suitable for modern workshop safety and cleanliness standards?
Yes. The machine features a fully enclosed protective housing with superior waterproof sealing and a sleek, minimalist design. The lightweight sliding doors are integrated with safety interlocks, ensuring full compliance with high-standard modern workshop requirements for both operator safety and environmental cleanliness.
