Frequently Asked Questions
Q1: What is the difference between the NXX-26AS and the NXX-36AS models?
The NXX-26AS features a 65° slant bed, a spindle bore of Φ36mm, max bar capacity of Φ25mm, and a total power of 22kW, 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 18kW. The NXX-36AS also offers a larger max turning length (200mm) and greater machine weight (4600kg), making it suited for heavier workpieces.
Q2: What is the advantage of the synchronized twin-spindle and dual-gang-tooling design?
The synchronized twin-spindle and dual gang tool post system allows for dynamic part hand-off between the main and sub-spindles without manual re-clamping. This enables complete multi-surface machining in a single setup, significantly reducing geometric tolerances, improving part consistency, and increasing overall production efficiency.
Q3: What positioning accuracy can these CNC turning centers achieve?
Both the NXX-26AS and NXX-36AS achieve a repeatability of ±0.0025mm on X1/X2 and Z1/Z2 axes. Spindle runout accuracy is ≤0.003mm and spindle face flatness is ≤0.01mm/Φ100, ensuring micron-level precision suitable for high-tolerance manufacturing applications.
Q4: What type of tooling system is used, and how many tools can it hold?
Both models use a T-Type Gang Tooling system (gang-type tool post), which supports up to 16 tools. The O.D. tool size is 20×20mm and the boring bar diameter is Φ25mm. This configuration ensures rapid and seamless tool indexing for maximized throughput in high-volume production environments.
Q5: How does the machine ensure thermal stability and long-term operational reliability?
The feed system uses pre-tensioned precision ball screws with an automatic lubrication system to minimize thermal displacement. The hydraulic system is equipped with premium Taiwanese variable pumps and an integrated air cooler, guaranteeing stable oil temperature and quiet operation even during prolonged machining cycles.
Q6: Is the machine suitable for modern workshop safety and environmental standards?
Yes. The machine features a fully enclosed protective housing with superior waterproof sealing and lightweight sliding doors integrated with safety interlocks. This design ensures full compliance with high-standard modern workshop requirements for operator safety, environmental cleanliness, and ease of chip disposal via the ergonomically designed slant bed.
