Product Description

Key Structural Features

To meet the demands of heavy-duty and high-precision machining, this machine features a monolithic cartridge-type spindle design. It is equipped with a '3-front, 2-rear' configuration of imported precision-grade bearings and driven by a high-performance spindle servo motor. This setup ensures high rigidity, superior accuracy, and consistently stable speeds, effortlessly handling heavy-load tasks. The machine bed is cast from high-quality iron using the resin sand process. The 30° slant bed structure, reinforced with dense internal ribbing, significantly enhances structural rigidity and vibration dampening, while simultaneously optimizing the ergonomic workspace and chip evacuation efficiency.

The motion axes are equipped with high-rigidity linear guideways and precision pre-tensioned ball screws, which are directly coupled to the servo motors via flexible couplings. This configuration, integrated with an intelligent automated lubrication system, ensures forced lubrication for both rails and screws. This results in superior positioning accuracy, minimized thermal deformation, and achieves rapid traverse speeds of up to 30 m/min.

Hydraulic station incorporates renowned Taiwanese variable displacement pumps, hydraulic motors, and solenoid valves. Equipped with a high-efficiency air-cooling system, it ensures low operational noise and consistent oil temperature control, providing a reliable power source for long-term continuous operation.

Available with either hydraulic or servo rotary turrets, the system offers superior rigidity and rapid tool-changing speeds. It supports bi-directional shortest-path tool selection, with an indexing time of only 0.3–0.5 seconds. The tool capacity remains unaffected by workpiece size, making it ideally suited for heavy-duty machining of disk-type components.

The machine features a fully enclosed splash guard with a modern aesthetic and superior sealing performance. The sliding doors operate smoothly and are equipped with a safety interlocking mechanism, ensuring maximum operator protection and comprehensive equipment safety.

Frequently Asked Questions
Q What is the difference between the NXX-46B and NXX-46BL models?
The NXX-46BL offers a larger max swing over bed (Φ500mm vs Φ480mm), a greater max machining length (360mm vs 320mm), a larger swing over turret carriage (Φ220mm vs Φ125mm), and a higher X/Z axis servo motor power (1.8Kw vs 1.3Kw), making it better suited for larger disk-type workpieces.
Q What type of spindle bearing configuration does this machine use?
The machine uses a monolithic cartridge-type spindle with a '3-front, 2-rear' configuration of imported precision-grade bearings, driven by a high-performance spindle servo motor to ensure high rigidity, superior accuracy, and stable speeds under heavy-load conditions.
Q What is the maximum rapid traverse speed of the axes?
The Z-axis achieves a rapid traverse speed of up to 30 m/min, while the X-axis reaches 24 m/min. This is made possible by the combination of high-rigidity linear guideways, precision pre-tensioned ball screws, and direct servo motor coupling.
