Frequently Asked Questions
Q
What is the difference between the NXX-26AS and NXX-36AS models?
The NXX-26AS features a 65° slant bed angle, a max swing diameter of Φ400mm, a spindle bore of Φ36mm, and a total power of 22kW. The NXX-36AS has a 45° slant bed, a larger max swing of Φ500mm, a spindle bore of Φ45mm, and a total power of 18kW — making it better suited for larger-diameter workpieces.
Q
What is the advantage of the synchronized twin-spindle design?
The synchronized twin-spindle system enables dynamic part hand-off between the main and sub-spindles without manual re-clamping. This allows complete multi-surface machining in a single setup, significantly reducing geometric errors and improving part-to-part consistency and production efficiency.
Q
What type of tooling system does this machine use?
Both models use a T-Type Gang Tooling system (Gang-type Tooling), supporting up to 16 tools simultaneously. The gang tool post supports versatile multi-tool configurations with O.D. tool size of 20×20mm and boring bar diameter of Φ25mm, enabling rapid and seamless tool indexing.
Q
What positioning accuracy can these CNC lathes achieve?
Both the NXX-26AS and NXX-36AS achieve a repeatability of ±0.0025mm on both X and Z axes, with spindle runout accuracy of ≤0.003mm and coaxiality for synchronization of ≤0.01mm — meeting the demands of high-precision manufacturing applications.
Q
How does the hydraulic and cooling system ensure stable long-term operation?
The machine is equipped with premium Taiwanese variable pumps and solenoid valves, along with an integrated air cooler. This configuration maintains optimal oil temperature stability and quiet operation even during extended machining cycles, minimizing thermal displacement and ensuring consistent accuracy.
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 lightweight sliding doors integrated with safety interlocks.
