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
Q1: 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), and a higher max. turning diameter for disk/shaft components. It also has a slightly higher servo motor power (1.8Kw vs 1.3Kw) and total power consumption (12Kw vs 11Kw), making it better suited for heavier and larger workpiece machining.
Q2: 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 accuracy, and stable spindle performance even under heavy-load conditions.
Q3: What is the maximum spindle speed and rapid traverse rate of the NXX-46B/BL series?
Both models support a spindle speed range of 0–4000 r/min with continuously variable (CV) speed control. The Z-axis achieves a rapid traverse rate of up to 30 m/min, while the X-axis reaches 24 m/min, enabling efficient and productive machining cycles.
Q4: How does the turret system work on the NXX-46B/BL CNC lathe?
Both models are equipped with a standard servo indexing turret supporting up to 12 tools. The turret supports bi-directional shortest-path tool selection with a tool-to-tool indexing time of just 0.3 seconds. Hydraulic turret options are also available for applications requiring additional rigidity.
Q5: What lubrication system is used for the guideways and ball screws?
An intelligent automated lubrication system is integrated into the machine to provide forced lubrication for both the linear guideways and precision pre-tensioned ball screws. This minimizes wear, reduces thermal deformation, and ensures long-term positioning accuracy and reliability.
Q6: What safety features are included in the machine design?
The NXX-46B/BL series features a fully enclosed splash guard with smooth-operating sliding doors and a built-in safety interlocking mechanism. This ensures that the machine cannot be operated when the guard is open, providing maximum protection for the operator and surrounding equipment.
