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, offering 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, directly coupled to the servo motors via flexible couplings. Equipped with an intelligent automatic lubrication system for continuous forced lubrication to 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 tool-to-tool time of 0.3–0.5 seconds, ideally suited for 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

QWhat 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 suited for heavier-duty applications requiring a larger bore and more power.
QWhat type of spindle bearing arrangement is used in this CNC lathe?
The spindle uses imported precision bearings in a '3+2' layout — three bearings at the front and two at the rear. This arrangement delivers exceptional rotational accuracy, superior rigidity, and high load capacity during high-speed machining operations.
QWhat is the tool-to-tool indexing time, and how many tool stations are available?
Both models feature a 160-type, 10-station hydraulic indexing turret with a tool-to-tool indexing time of just 0.5 seconds for adjacent stations (0.3–0.5 seconds overall). The turret supports bi-directional shortest-path tool selection for maximum efficiency.
QWhat is the rapid traverse rate for the X and Z axes?
Both the X-axis and Z-axis support a rapid traverse rate of up to 30 m/min. This is achieved through high-rigidity precision linear guideways, pre-tensioned ball screws, and direct servo motor coupling, ensuring fast and accurate positioning.
QDoes the machine support long-shaft workpiece machining?
Yes. The machine is equipped with a hydraulic-controlled tailstock featuring a fully programmable/automatic quill with a travel of 80mm and a body travel of 480mm. This significantly expands the capability for processing long-shaft workpieces while maintaining superior stability.
QWhat safety and operator protection features are included?
The machine comes with a fully enclosed guarding system that provides superior coolant and chip containment. The sliding doors are engineered for effortless operation and are integrated with safety interlocking devices, ensuring maximum operator protection without compromising accessibility or convenience.
