Product Description

Structural Features
This CNC machine features a monolithic cartridge-type spindle unit designed for high rigidity, high precision, and heavy-duty machining. The spindle is supported by imported precision bearings in a '3+2' (front-triple, rear-double) layout, driven by a high-performance spindle servo system. This configuration ensures exceptional rotational accuracy, superior rigidity, and high load capacity during high-speed operations. The bed structure utilizes an integrated premium cast iron base with a 30° slant-bed design. Crafted using resin-sand casting and a reinforced rib-and-plate internal structure, it offers outstanding structural rigidity and vibration damping, while simultaneously optimizing operator ergonomics and chip evacuation paths.
X and Z axes feature high-rigidity precision linear guideways paired with pre-tensioned ball screws, which are directly coupled to the servo motors via flexible couplings. To ensure sustained accuracy, the system is equipped with an intelligent automatic lubrication system that provides continuous forced lubrication to the rails and screws. This configuration achieves superior positioning precision, minimizes thermal deformation, and enables rapid traverse rates of up to 30 m/min.
Hydraulic station is equipped with premium Taiwanese variable displacement pumps, hydraulic motors, and solenoid valves, integrated with a high-efficiency air-cooled heat exchanger to ensure low noise levels and stable oil temperatures. The machine offers a choice of hydraulic or servo rotary turrets, both featuring exceptional rigidity and rapid indexing. Supporting bi-directional shortest-path tool selection, the system achieves a lightning-fast tool-to-tool time of 0.3–0.5 seconds, making it ideally suited for the heavy-duty machining of disk-type components.
Hydraulic-controlled tailstock features a fully programmable/automatic quill, ensuring a robust structure and effortless operation. This configuration significantly expands the machine's capability for processing long-shaft workpieces while maintaining superior stability.
The machine is equipped with an aesthetically pleasing, fully enclosed guarding system that provides superior coolant and chip containment. The sliding doors are designed for effortless operation and are integrated with safety interlocking devices, ensuring an optimal balance between operator protection and convenience.

Frequently Asked Questions
Q What is the difference between the NXX-46D and NXX-52D models?
The primary differences lie in the spindle bore diameter (Φ56mm vs Φ62mm), max bar capacity (Φ45mm vs Φ51mm), spindle speed range (0–4000 r/min vs 0–3000 r/min), main motor power (7.5Kw vs 11Kw), and total power consumption (11Kw vs 14.5Kw). The NXX-52D is better suited for heavier-duty applications requiring a larger bore and more power.
Q What type of guideway system does this CNC lathe use?
Both models use high-rigidity precision linear guideways paired with pre-tensioned ball screws directly coupled to servo motors via flexible couplings. This configuration delivers superior positioning accuracy, minimal thermal deformation, and rapid traverse rates of up to 30 m/min on both X and Z axes.
Q How fast is the tool change (indexing) time on this machine?
The standard 160-10 Station Hydraulic Indexing Turret achieves a tool-to-tool indexing time of 0.5 seconds for adjacent stations. With the optional servo rotary turret, the tool-to-tool time can be as fast as 0.3–0.5 seconds, supporting bi-directional shortest-path tool selection for maximum efficiency.
Q What repeatability accuracy can be expected from the X and Z axes?
Both the X-axis and Z-axis achieve a repeatability accuracy of ±0.0025mm on both the NXX-46D and NXX-52D models. The spindle radial and axial run-out accuracy is ≤0.003mm, and spindle face flatness accuracy is ≤0.01mm/Φ100mm.
Q Is this CNC lathe suitable for machining long-shaft workpieces?
Yes. The machine is equipped with a hydraulic-controlled tailstock featuring a fully programmable/automatic quill (Φ80mm quill diameter, 80mm quill travel, 480mm body travel). This design significantly expands the machine's capability for processing long-shaft workpieces while maintaining superior stability and ease of operation.
Q What safety and operator-friendly features are included?
The machine features a fully enclosed guarding system with sliding doors designed for effortless operation. Safety interlocking devices are integrated into the doors to ensure operator protection. The 30° slant-bed design also optimizes chip evacuation and operator ergonomics, while the intelligent automatic lubrication system ensures long-term reliable performance with minimal maintenance.
