Product Description

Machine Structural Features
Our high-rigidity cartridge-type spindle system features an integrated monoblock structure, paired with a precision-grade imported bearing layout in a 'front-3-rear-2' configuration. Driven by a dedicated rear-mounted servo motor, it delivers exceptional speed stability and heavy-duty cutting capability, making it ideal for high-precision machining scenarios. The base is constructed from high-strength cast iron using a resin-sand casting process. The 45° inclined bed design, combined with a dense reinforcement rib layout, significantly enhances structural rigidity and vibration dampening while optimizing ergonomic operation and chip evacuation efficiency.
Each X/Z axis is directly coupled with pre-tensioned ball screws via flexible couplings and driven by high-performance servo motors. Combined with high-precision linear guideways and an intelligent centralized lubrication system, the machine achieves high-speed (30m/min rapid traverse) and high-precision positioning with superior thermal compensation. The T-type gang tooling module supports versatile tool configurations, ensuring ultra-fast indexing and interference-free operation.
The innovative twin-spindle and twin-gang configuration supports simultaneous machining and dynamic synchronization between the main and sub-spindles. By completing all processes in a single setup, the system effectively guarantees superior geometric tolerances and eliminates cumulative errors from secondary handling.
The hydraulic unit incorporates a Taiwan-branded variable displacement pump and a high-efficiency air-cooling system, ensuring ultra-quiet operation and stable temperature control during continuous production.
The machine features a fully enclosed guarding structure with a modern, aesthetic design and superior sealing performance. The lightweight sliding doors are equipped with a safety interlock mechanism, perfectly balancing operational convenience with workplace safety.

Frequently Asked Questions
Q What is the key difference between the NXX-26AS and NXX-36AS models?
The NXX-26AS and NXX-36AS differ primarily in machining capacity and size. The NXX-36AS offers a larger max. swing over bed (Φ500mm vs Φ400mm), greater max. turning length (200mm vs 100mm), and a larger bore diameter (Φ45mm vs Φ36mm), making it suitable for heavier and larger workpieces. The NXX-26AS features a higher slant bed angle (65° vs 45°) and greater X-axis rapid traverse rate (30m/min vs 24m/min).
Q What advantages does the twin-spindle and twin-gang configuration offer?
The twin-spindle and twin-gang configuration enables simultaneous machining and dynamic synchronization between the main and sub-spindles. All processes can be completed in a single setup, which eliminates cumulative errors caused by secondary handling and guarantees superior geometric tolerances — significantly improving both productivity and part quality.
Q What type of spindle bearing configuration is used in these machines?
Both models use a high-rigidity cartridge-type spindle system with an integrated monoblock structure. The spindle employs a precision-grade imported bearing layout in a 'front-3-rear-2' configuration, driven by a dedicated rear-mounted servo motor. This design delivers exceptional speed stability and heavy-duty cutting capability for high-precision machining applications.
Q How does the machine achieve high-precision positioning?
High-precision positioning is achieved through the combination of pre-tensioned ball screws directly coupled via flexible couplings, high-performance servo motors, high-precision linear guideways, and an intelligent centralized lubrication system. The system also incorporates superior thermal compensation, achieving a repeatability of ±0.0025mm on both X and Z axes.
Q What tooling system is used, and how many tools can be mounted?
Both the NXX-26AS and NXX-36AS use a T-type gang tooling module as the standard turret type. 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. The gang tooling design ensures ultra-fast indexing and interference-free operation.
Q What safety and operational features does the machine enclosure provide?
The machine is equipped with a fully enclosed guarding structure featuring a modern aesthetic design and superior sealing performance. The lightweight sliding doors incorporate a safety interlock mechanism that prevents accidental opening during operation, ensuring a safe working environment while maintaining convenient operator access during setup and inspection.
