Product Description

Structural Features
1
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.
2
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 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.
3
Hydraulic station is equipped with premium 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.
4
Hydraulic-controlled tailstock features a fully programmable/automatic quill, ensuring a robust structure and effortless operation. This configuration significantly expands the capability for processing long-shaft workpieces while maintaining superior stability.
5
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 (Φ 56mm vs. Φ 62mm), max. bar capacity (Φ 45mm vs. Φ 51mm), 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 suited for heavier-duty applications requiring a larger bore and higher torque.
Q What type of spindle bearing configuration is used in these CNC lathes?
Both models use a '3+2' bearing layout — three precision bearings at the front and two at the rear. This arrangement, combined with imported precision bearings and a high-performance spindle servo system, ensures exceptional rotational accuracy, rigidity, and load capacity during high-speed operations.
Q What is the tool-change speed of the turret system?
The standard 160-10 Station Hydraulic Indexing Turret achieves a tool-to-tool indexing time of just 0.5 seconds (adjacent stations). The system supports bi-directional shortest-path tool selection, and optional servo rotary turrets can achieve tool-to-tool times as fast as 0.3 - 0.5 seconds.
Q How does the automatic lubrication system work on the X and Z axes?
The automatic lubrication system delivers 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 precision components over long-term operation.
Q Is the tailstock programmable, and what workpiece lengths can it support?
Yes. The hydraulic-controlled tailstock features a fully programmable/automatic quill with a travel of 80mm and a body travel of 480mm. This design is specifically optimized for long-shaft workpiece processing, providing robust support and superior stability throughout the machining cycle.
Q What safety and enclosure features does the machine include?
The machine is equipped with a fully enclosed guarding system that provides superior coolant and chip containment. The sliding doors are engineered for smooth, effortless operation and incorporate safety interlocking devices, ensuring comprehensive operator protection while maintaining easy access for setup and maintenance.
