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 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.

Both models feature a monolithic cartridge-type spindle design equipped with imported precision-grade bearings in a '3-front, 2-rear' configuration, driven by a high-performance spindle servo motor to ensure high rigidity and stable speed under heavy-load tasks.
The 30° slant bed structure is cast from high-quality resin sand iron and reinforced with dense internal ribbing. This design greatly enhances structural rigidity, dampens vibration, improves ergonomic access, and optimizes chip evacuation efficiency.
The motion system, featuring high-rigidity linear guideways, precision pre-tensioned ball screws, and an automated lubrication system, achieves rapid traverse speeds of up to 30 m/min.
The system supports hydraulic or servo rotary turrets with bi-directional shortest-path tool selection, offering a rapid tool-to-tool indexing time of only 0.3 to 0.5 seconds.
The machines are built with a fully enclosed splash guard offering superior sealing performance. The sliding doors operate smoothly and include a safety interlocking mechanism for maximum operator and equipment protection.
The NXX-46BL has a larger max swing over bed (Φ500mm vs Φ480mm), longer max machining length (360mm vs 320mm), and a larger swing over the turret carriage (Φ220mm vs Φ125mm) compared to the NXX-46B.
