Product Description

Machine Structural Features
Spindle & Bed Rigidity
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.
Axis Drive & Tooling
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.
Twin-Spindle Synchronization
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.
Hydraulic & Cooling Unit
The hydraulic unit incorporates a famous Taiwan-branded variable displacement pump and a high-efficiency air-cooling system, ensuring ultra-quiet operation and stable temperature control during continuous production.
Enclosed Guarding & Safety
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 main difference between the NXX-26AS and NXX-36AS models?
The NXX-26AS features a 65° slant bed angle, a max swing over bed of Φ400mm, and a total power capacity of 22kW, while the NXX-36AS has a 45° slant bed, a larger max swing of Φ500mm, and a total power of 18kW. The NXX-36AS also supports a larger max bar capacity (Φ35mm vs. Φ25mm) and a higher machine weight of 4,600kg.
Q
What type of spindle bearing configuration does this machine use?
The machine uses a high-rigidity cartridge-type spindle system with an integrated monoblock structure. It features a precision-grade imported bearing layout in a 'front-3-rear-2' configuration, which ensures exceptional speed stability and heavy-duty cutting performance suitable for high-precision machining.
Q
Does the machine support simultaneous machining with both spindles?
Yes. The twin-spindle and twin-gang configuration supports simultaneous machining and dynamic synchronization between the main and sub-spindles. All processes can be completed in a single setup, which eliminates cumulative errors from secondary handling and guarantees superior geometric tolerances.
Q
What is the positioning repeatability of the X and Z axes?
Both the X1/X2 and Z1/Z2 axes achieve a positioning repeatability of ±0.0025mm on both models (NXX-26AS and NXX-36AS). This high precision is achieved through directly coupled pre-tensioned ball screws, high-performance servo motors, and high-precision linear guideways.
Q
What tooling system does the machine use and how many tools can it hold?
Both models use a T-type gang tooling module (Gang-type Tooling) as the standard turret type, supporting a maximum tool capacity of 16 pieces. O.D. tools are sized at 20×20mm, and the boring bar diameter is Φ25mm. The system ensures ultra-fast indexing and interference-free operation.
Q
How is the machine's hydraulic and cooling system designed for continuous production?
The hydraulic unit incorporates a Taiwan-branded variable displacement pump combined with a high-efficiency air-cooling system.
