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

Q1: 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 (7.5 Kw vs. 11 Kw), and total power consumption (11 Kw vs. 14.5 Kw). The NXX-52D is better suited for heavier workpieces requiring larger bore capacity and higher torque.
Q2: What type of spindle bearing configuration does this CNC lathe use?
The machine uses a '3+2' bearing layout — three precision bearings at the front and two at the rear — with imported precision bearings. This configuration delivers exceptional rotational accuracy, superior rigidity, and high load capacity, especially during high-speed operations.
Q3: What is the tool-to-tool indexing time for the turret?
The standard hydraulic indexing turret achieves a tool-to-tool time of 0.3–0.5 seconds, supporting bi-directional shortest-path tool selection. This rapid indexing makes the machine highly efficient for disk-type component machining.
Q4: How does the automatic lubrication system work on the X and Z axes?
The intelligent automatic lubrication system provides continuous forced lubrication to both the linear guideways and ball screws on the X and Z axes. This ensures sustained positioning accuracy, minimizes thermal deformation, and extends the service life of critical components.
Q5: Is the tailstock programmable, and what workpieces does it support?
Yes, the hydraulic-controlled tailstock features a fully programmable/automatic quill. It is designed to significantly expand the machine's capability for processing long-shaft workpieces, maintaining superior clamping stability throughout the operation.
Q6: What safety features are included with the machine guarding system?
The machine is equipped with a fully enclosed guarding system offering superior coolant and chip containment. The sliding doors are lightweight and easy to operate, and are integrated with safety interlocking devices that prevent accidental access during machining, ensuring both operator safety and operational convenience.
