Product Description

Structural Features
Spindle System
The spindle system features a high-precision, high-rigidity cartridge-type design, specifically optimized for heavy-duty machining. The structural configuration utilizes a 'front-three-rear-two' (triplex-front, duplex-rear) arrangement of imported precision-grade bearings. Combined with a direct-drive spindle servo motor, the system achieves exceptional rotational accuracy, dynamic rigidity, and speed stability, ensuring superior machining quality and high efficiency even under heavy cutting conditions.
Machine Bed
The machine bed is constructed from premium monolithic cast iron using a resin-sand precision casting process with a 30° slant layout. The internal structure is reinforced with high-rigidity ribbing, significantly enhancing the machine's natural frequency and damping characteristics. This design offers outstanding anti-vibration performance. Furthermore, the slanted bed provides the operator with an unobstructed view and easier access, while ensuring gravity-assisted chip removal for enhanced efficiency and workplace safety.
Feed Mechanism
The feed mechanism operates through the synergy of high-rigidity linear guideways and precision pre-tensioned ball screws. Both X and Z axes are directly driven by high-performance servo motors via flexible couplings, eliminating backlash and enhancing transmission efficiency. An intelligent centralized lubrication system provides forced lubrication and cooling to the guideways and ball screws, supporting rapid traverse rates of up to 30 m/min while maintaining exceptional positioning accuracy and thermal stability.
Hydraulic System
The hydraulic system integrates premium components, including variable displacement pumps, hydraulic motors, and solenoid valves, complemented by a high-efficiency air-cooled radiator. This setup ensures low-noise operation and precise oil temperature control, guaranteeing reliable hydraulic movements. The machine offers a choice of hydraulic or servo indexing turrets, featuring a robust construction with rapid tool changes (0.3–0.5 sec) and bi-directional shortest-path indexing, specifically engineered to meet the rigorous demands of heavy-duty disk-type workpiece machining.
Tailstock
The tailstock is hydraulically driven, enabling automatic quill extension and retraction. It offers superior rigidity and ease of adjustment, significantly expanding the machine's capability for processing long-shaft workpieces.
Protection Guard
The machine is equipped with an aesthetic fully-enclosed protection guard, providing excellent waterproof and chip-proof performance. The sliding doors operate smoothly and are integrated with safety interlocking protection. This design not only enhances the machine's overall appearance but also provides comprehensive safety assurance for both the operator and the equipment.

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 designed for heavier-duty applications requiring a larger bore and higher torque output.
Q Why does the machine use a 30° slant bed design?
The 30° slanted bed design offers multiple advantages: it improves chip removal efficiency through gravity, provides the operator with a clearer and more accessible view of the workpiece, and enhances the structural rigidity of the machine. The slant configuration also helps maintain better thermal stability and reduces vibration during heavy-duty cutting operations.
Q What type of turret is standard on the NXX-46D and NXX-52D, and how fast is the tool change?
Both models come standard with a 160-10 Station Hydraulic Indexing Turret, accommodating up to 10 tools. The tool-to-tool indexing time is 0.5 seconds, with bi-directional shortest-path indexing. An optional servo indexing turret is also available, with rapid tool change times of 0.3–0.5 seconds, making it highly efficient for complex multi-tool machining tasks.
Q What positioning accuracy can I expect from the X and Z axes?
Both the X-axis and Z-axis achieve a repeatability accuracy of ±0.0025 mm. This is made possible by the combination of high-rigidity linear guideways, precision pre-tensioned ball screws, and direct-drive high-performance servo motors with flexible couplings that eliminate backlash. The spindle radial/axial run-out is also controlled to ≤ 0.003 mm.
Q Is the tailstock hydraulically operated, and what workpieces can it support?
Yes, the tailstock is hydraulically driven, enabling automatic quill extension and retraction. With a quill diameter of Φ80mm, a quill travel of 80mm, and a body travel of 480mm (manual/hydraulic), it significantly expands the machine's capability for processing long-shaft workpieces. The NXX-46D uses a MT4 taper while the NXX-52D uses a MT5 taper for heavier workpiece support.
Q What safety and protection features are included with these CNC lathes?
The machines are equipped with a fully-enclosed aesthetic protection guard that provides excellent waterproof and chip-proof performance. The sliding doors operate smoothly and feature safety interlocking protection to prevent accidental access during operation. The hydraulic system also incorporates a high-efficiency air-cooled radiator to maintain stable oil temperatures, and the centralized lubrication system ensures continuous protection of guideways and ball screws.
