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. swing over turret carriage (Φ220mm vs Φ125mm), a longer max. machining length (360mm vs 320mm), and a higher servo motor power (1.8Kw vs 1.3Kw), making it better suited for larger disk-type workpieces and heavier cutting loads.
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. This design ensures high rigidity, superior rotational accuracy, and stable performance under heavy-load machining conditions.
Q How fast is the tool-changing speed on the turret?
The servo indexing turret achieves a tool-to-tool indexing time of just 0.3 seconds. It supports bi-directional shortest-path tool selection, which minimizes non-cutting time and significantly improves overall machining efficiency.
Q What rapid traverse speeds do the X and Z axes achieve?
The X-axis achieves a rapid traverse rate of 24 m/min, while the Z-axis reaches up to 30 m/min. These speeds are made possible by the high-rigidity linear guideways and precision pre-tensioned ball screws directly coupled to servo motors.
Q How does the machine ensure long-term precision and minimal thermal deformation?
The machine integrates an intelligent automated lubrication system that provides forced lubrication for both linear rails and ball screws. Combined with the high-efficiency air-cooled hydraulic station that maintains consistent oil temperature, thermal deformation is minimized, ensuring sustained positioning accuracy over long-term continuous operation.
Q What safety features does the machine enclosure provide?
The machine is equipped with a fully enclosed splash guard featuring a modern design and superior sealing performance. The sliding doors operate smoothly and incorporate a safety interlocking mechanism, which prevents the machine from operating when the door is open, ensuring maximum operator safety and comprehensive equipment protection.
