Product Description

Key Structural Features
The unit adopts a professional-grade sleeve spindle with a monolithic design, supported by a high-precision 3-front/2-rear bearing configuration. Coupled with a rear-drive servo system, it maintains exceptional stiffness and operational stability during heavy loads. The 65° slant bed, engineered from high-grade resin-sand casting with an intensive ribbed-plate architecture, combines superior anti-vibration properties with an ergonomic workflow for seamless chip disposal.
Precision Feed System & Tooling
High-Speed Feed Mechanism: Each axis features a direct-drive configuration with servo motors and pre-tensioned precision ball screws. Integrated with high-rigidity linear guideways and an automatic lubrication system, it achieves a 30 m/min rapid traverse and micron-level positioning accuracy while effectively minimizing thermal displacement.
T-Type Gang Tooling: The unique T-style gang tool post supports versatile multi-tool configurations, ensuring rapid and seamless tool indexing for maximized throughput.
Synchronized Twin-Spindle & Dual-Gang-Tooling
The synchronized operation of twin spindles and dual gang tool posts enables dynamic part hand-off (re-gripping) between the main and sub-spindles. This allows for complete multi-surface machining in a single setup, significantly reducing geometric tolerances and ensuring superior part consistency.
Hydraulic & Cooling Performance: Equipped with premium Taiwanese variable pumps and solenoid valves, the system features an integrated air cooler to guarantee quiet operation and optimal oil temperature stability during prolonged cycles.
The machine features a fully enclosed protective housing with a sleek, minimalist aesthetic and superior waterproof sealing. The lightweight sliding doors are integrated with safety interlocks, ensuring full compliance with high-standard modern workshop requirements for operator safety and environmental cleanliness.

Frequently Asked Questions
Q1: What is the difference between the NXX-26AS and NXX-36AS models?
The NXX-26AS features a 65° slant bed with a spindle bore of Φ36mm, max bar capacity of Φ25mm, and a total power of 22kW, making it ideal for smaller, high-precision parts. The NXX-36AS uses a 45° slant bed with a larger Φ45mm bore, Φ35mm bar capacity, and a machine weight of 4,600kg, suited for heavier and larger workpieces up to Φ450mm diameter.
Q2: What is the advantage of the synchronized twin-spindle design?
The synchronized twin-spindle configuration allows dynamic part hand-off between the main and sub-spindles without operator intervention. This enables complete multi-surface machining in a single setup, dramatically reducing cycle times, minimizing geometric tolerances, and ensuring superior part-to-part consistency.
Q3: What positioning accuracy can the NXX series CNC lathe achieve?
Both models achieve a repeatability of ±0.0025mm on both X and Z axes, with spindle runout accuracy of ≤0.003mm and spindle face flatness of ≤0.01mm/Φ100. The coaxiality between main and sub-spindles for synchronization is ≤0.01mm, ensuring micron-level precision for demanding applications.
Q4: What type of tooling system does the NXX series use, 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 simultaneously. The O.D. tool size is 20×20mm and the boring bar diameter is Φ25mm. This design enables rapid, seamless tool indexing for maximized production throughput.
Q5: How does the machine ensure thermal stability and long-term precision during continuous operation?
The machine integrates pre-tensioned precision ball screws with an automatic lubrication system and high-rigidity linear guideways to minimize thermal displacement. The hydraulic system is equipped with an integrated air cooler using premium Taiwanese variable pumps and solenoid valves, maintaining optimal oil temperature and ensuring stable precision during prolonged machining cycles.
Q6: Does the NXX series meet modern workshop safety and environmental standards?
Yes. The NXX series features a fully enclosed protective housing with superior waterproof sealing and a minimalist aesthetic. 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.
