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
Q What is the difference between the NXX-26AS and NXX-36AS models?
The NXX-26AS features a 65° slant bed with a max swing diameter of Φ400mm and a bar capacity of Φ25mm, while the NXX-36AS offers a 45° slant bed, a larger max swing diameter of Φ500mm, and a bar capacity of Φ35mm — making it suited for heavier, larger-diameter workpieces.
Q What does the synchronized twin-spindle feature enable?
The synchronized twin-spindle and dual gang tool post system enables dynamic part hand-off (re-gripping) between the main and sub-spindles. This allows complete multi-surface machining in a single setup, significantly reducing geometric tolerances and improving part consistency.
Q What rapid traverse rate does the machine achieve?
The NXX-26AS achieves a rapid traverse rate of 30 m/min on both X and Z axes. The NXX-36AS achieves 24 m/min on the X axis and 30 m/min on the Z axis, supported by direct-drive servo motors and pre-tensioned precision ball screws.
Q How is thermal displacement minimized in these CNC lathes?
Thermal displacement is minimized through the integration of high-rigidity linear guideways, an automatic lubrication system, and an integrated air cooler within the hydraulic circuit. These features maintain optimal oil temperature and structural stability during prolonged machining cycles.
Q What is the positioning repeatability of these machines?
Both the NXX-26AS and NXX-36AS achieve a positioning repeatability of ±0.0025mm on both X and Z axes, with a spindle runout accuracy of ≤0.003mm, ensuring micron-level precision for demanding applications.
Q What safety and enclosure features are included?
The machines feature a fully enclosed protective housing with superior waterproof sealing and a sleek minimalist design. Lightweight sliding doors are integrated with safety interlocks to ensure full compliance with modern workshop safety and environmental cleanliness standards.
