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 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 accommodates heavier workpieces up to 4600kg machine weight, suited for larger-diameter turning applications.
Q
What are the advantages of the synchronized twin-spindle and dual gang tooling design?
The synchronized twin-spindle and dual gang tool post system enables automatic part hand-off between the main and sub-spindles without manual re-clamping. This allows complete multi-surface machining in a single setup, dramatically reducing geometric tolerances, improving part-to-part consistency, and maximizing production throughput.
Q
How does the precision feed system achieve micron-level positioning accuracy?
Each axis uses a direct-drive configuration combining servo motors with pre-tensioned precision ball screws. This is further enhanced by high-rigidity linear guideways and an automatic lubrication system. Together, these components achieve a rapid traverse rate of 30 m/min and a repeatability of ±0.0025mm, while minimizing thermal displacement during extended operations.
Q
What type of tooling system does the machine use, and how many tools can it hold?
Both the NXX-26AS and NXX-36AS use a Gang-type Tooling system with a T-style gang tool post. Each machine supports a maximum tool capacity of 16 pieces, accommodating O.D. tools of 20×20mm and boring bars up to Φ25mm in diameter, enabling versatile and rapid tool indexing for high-mix production.
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, paired with an integrated air cooler. This combination maintains optimal hydraulic oil temperature stability throughout prolonged machining cycles, reduces noise levels, and prevents performance degradation caused by overheating — ensuring consistent and reliable long-term operation.
Q
What safety and environmental features does the machine enclosure provide?
The machine features a fully enclosed protective housing with a sleek, minimalist design and superior waterproof sealing. The lightweight sliding doors are integrated with safety interlocks that prevent accidental opening during operation. This ensures full compliance with modern workshop safety standards, protects operators from coolant and chip hazards, and maintains a clean working environment.
