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

Q1: What is the key 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 spindle motor power of 7.5 Kw, while the NXX-36AS has a 45° slant bed, a larger max swing of Φ500mm, and a spindle motor power of 5.5 Kw. The NXX-36AS also supports a larger max bar capacity (Φ35mm vs. Φ25mm) and greater machine weight (4600 kg vs. 3500 kg), making it more suitable for larger workpiece machining.

Q2: What is the advantage of the twin-spindle and twin-gang configuration?

The twin-spindle and twin-gang configuration allows simultaneous machining and dynamic synchronization between the main and sub-spindles. All processes are completed in a single setup, which eliminates cumulative errors from secondary handling and guarantees superior geometric tolerances and dimensional consistency.

Q3: What type of guideways and ball screws are used on these CNC lathes?

Both models use high-precision linear guideways combined with pre-tensioned ball screws that are directly coupled to servo motors via flexible couplings. This configuration achieves a rapid traverse rate of up to 30 m/min and positioning repeatability of ±0.0025 mm, ensuring both speed and accuracy.

Q4: How does the hydraulic system ensure stable and quiet operation?

The hydraulic unit incorporates a Taiwan-branded variable displacement pump combined with a high-efficiency air-cooling system. This design minimizes noise levels and maintains stable oil temperature during continuous production cycles, contributing to long-term reliability and consistent machining performance.

Q5: What safety features are included in the machine guarding structure?

The machines feature 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 that prevents operation when the door is open, ensuring operator safety while maintaining convenient access for workpiece loading and inspection.

Q6: What is the maximum tool capacity and tool size supported by the gang-type tooling system?

Both the NXX-26AS and NXX-36AS support a maximum tool capacity of 16 tools using a gang-type tooling system. The O.D. tool size is 20×20 mm, and the boring bar diameter is Φ25 mm. The T-type gang tooling module supports versatile tool configurations and ensures ultra-fast indexing with interference-free operation.
