China Suppliers NXX-46BL Slant Bed CNC Lathe with Rotary Turret - Precision Manufacturing from Factory
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 the NXX-46BL models?
The NXX-46BL offers a larger max. swing over bed (Φ500mm vs Φ480mm), a greater max. machining length (360mm vs 320mm), and a larger max. swing over turret carriage (Φ220mm vs Φ125mm). The NXX-46BL is better suited for machining larger disk-type components, while both models share the same spindle bore, speed range, and turret configuration.
Q
What type of spindle design does this CNC lathe use, and why is it important?
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 consistently stable speeds — all critical for heavy-duty and high-precision machining applications.
Q
What is the maximum rapid traverse speed of the Z-axis?
Both the NXX-46B and NXX-46BL achieve a Z-axis rapid traverse rate of 30 m/min, enabled by high-rigidity linear guideways and precision pre-tensioned ball screws directly coupled to servo motors via flexible couplings.
Q
How fast is the tool-changing (indexing) time on the turret?
The servo indexing turret supports bi-directional shortest-path tool selection with an indexing time of only 0.3 seconds (0.3–0.5 seconds range). Both models support up to 12 tools and are compatible with O.D. tools of 25×25mm and boring bars up to Φ32mm.
Q
What repeatability accuracy can this machine achieve?
Both models achieve a repeatability accuracy of ±0.0025mm on both the X-axis and Z-axis. Spindle radial and axial run-out is ≤0.003mm, and spindle facing flatness accuracy is ≤0.01mm over Φ100mm, making these machines suitable for high-precision part production.
Q
What safety and protection features does this machine include?
The machine is equipped with a fully enclosed splash guard featuring a modern aesthetic and superior sealing performance. The sliding doors operate smoothly and include a safety interlocking mechanism to ensure maximum operator protection. The hydraulic station also incorporates a high-efficiency air-cooling system for stable and safe long-term operation.
