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 for NXX-46D vs. Φ62mm for NXX-52D), maximum 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). Both models share the same bed dimensions, travel ranges, and turret configuration.
Q What type of guideway system does this CNC lathe use, and what are its advantages?
The machine uses high-rigidity precision linear guideways paired with pre-tensioned ball screws directly coupled to servo motors. This setup, combined with an intelligent automatic lubrication system, delivers superior positioning precision (±0.0025mm repeatability), minimizes thermal deformation, and supports rapid traverse rates of up to 30 m/min on both X and Z axes.
Q How fast is the turret tool-changing speed, and how many tool stations are available?
The standard 160-type hydraulic indexing turret supports up to 10 tool stations. With bi-directional shortest-path tool selection, the tool-to-tool indexing time is just 0.3–0.5 seconds (adjacent station time: 0.5 seconds), making it highly efficient for high-volume disk-type component machining.
Q What is the bed design of this CNC lathe, and why is a 30° slant-bed used?
The machine features an integrated premium cast iron base with a 30° slant-bed design, manufactured using resin-sand casting with a reinforced rib-and-plate internal structure. The slant-bed configuration provides outstanding structural rigidity and vibration damping, while also optimizing chip evacuation and improving operator ergonomics for easier access to the workpiece.
Q Is the tailstock programmable, and what workpieces can it support?
Yes. The hydraulic-controlled tailstock features a fully programmable/automatic quill (Φ80mm diameter, 80mm travel) with a Morse Taper 4# (NXX-46D) or 5# (NXX-52D) spindle. It supports a tailstock body travel of 480mm, significantly expanding the machine's capability for processing long-shaft workpieces with superior stability and ease of operation.
Q What safety and enclosure features does this CNC lathe provide?
The machine is equipped with a fully enclosed guarding system that ensures superior coolant and chip containment during operation. The sliding doors are ergonomically designed for effortless opening and closing, and are integrated with safety interlocking devices that prevent accidental access during machining, ensuring a high level of operator protection without compromising workflow convenience.
