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 famous 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 features a 65° slant bed angle, a larger spindle motor power of 7.5 Kw, and a higher X-axis rapid traverse rate of 30 m/min. The NXX-36AS uses a 45° slant bed, supports a larger max. bar capacity of Φ35mm, and has a greater machine weight of 4600 kg, making it more suitable for larger workpiece machining applications.
Q What type of spindle bearing configuration is used in these CNC lathes?
Both models use a high-rigidity cartridge-type spindle system with an integrated monoblock structure, featuring a precision-grade imported bearing layout in a 'front-3-rear-2' configuration. This design ensures exceptional speed stability and heavy-duty cutting capability for high-precision machining.
Q Can the NXX series machines perform complete part machining in a single setup?
Yes. The innovative twin-spindle and twin-gang configuration supports simultaneous machining and dynamic synchronization between the main and sub-spindles. This allows all processes to be completed in a single setup, guaranteeing superior geometric tolerances and eliminating cumulative errors from secondary handling.
Q What is the positioning repeatability of the X and Z axes?
Both the X1/X2 and Z1/Z2 axes on the NXX-26AS and NXX-36AS achieve a repeatability of ±0.0025 mm. This is made possible by the combination of pre-tensioned ball screws, high-performance servo motors, high-precision linear guideways, and an intelligent centralized lubrication system.
Q What tooling system does the NXX series use, and how many tools can it hold?
The NXX series uses a T-type gang tooling module as the standard turret type, supporting up to 16 tools. It accommodates O.D. tools of 20×20 mm and boring bars up to Φ25 mm in diameter, ensuring versatile tool configurations with ultra-fast indexing and interference-free operation.
Q How does the hydraulic and guarding system contribute to safe and stable operation?
The hydraulic unit incorporates a Taiwan-branded variable displacement pump with a high-efficiency air-cooling system, ensuring ultra-quiet operation and stable temperature control during continuous production.
