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 CNC lathe 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 (7.5 Kw vs 11 Kw), and total power consumption (11 Kw vs 14.5 Kw). The NXX-52D is better suited for larger-diameter workpieces and heavier-duty operations.
Q What type of spindle bearing configuration is used in these CNC lathes?
The spindle is supported by imported precision bearings arranged in a "3+2" layout — three bearings at the front and two at the rear. This configuration delivers exceptional rotational accuracy, high rigidity, and strong load-bearing capacity, making it ideal for high-speed and heavy-duty machining tasks.
Q How fast is the tool indexing speed on the turret?
The machine achieves a tool-to-tool indexing time of just 0.3–0.5 seconds, thanks to the high-performance hydraulic or servo rotary turret with bi-directional shortest-path tool selection. This rapid indexing capability significantly improves production efficiency, especially for disk-type component machining.
Q What guiding system is used for the X and Z axes?
Both X and Z axes use high-rigidity precision linear guideways paired with pre-tensioned ball screws, directly coupled to servo motors via flexible couplings. An intelligent automatic lubrication system provides continuous forced lubrication to both rails and screws, ensuring sustained accuracy, minimal thermal deformation, and rapid traverse rates up to 30 m/min.
Q Is the tailstock programmable, and can it handle long-shaft workpieces?
Yes. The hydraulic-controlled tailstock features a fully programmable and automatic quill with a travel of 80mm and a body travel of 480mm. This robust design significantly expands the machine's capability for processing long-shaft workpieces while maintaining superior stability and ease of operation.
Q What safety and enclosure features does this CNC lathe offer?
The machine is equipped with a fully enclosed guarding system that provides superior coolant and chip containment. The sliding doors are designed for effortless operation and incorporate safety interlocking devices, ensuring optimal operator protection while maintaining convenient access to the machining area.
