Product Description

Structural Features

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.
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 obstructed view and easier access, while ensuring gravity-assisted chip removal for enhanced efficiency and workplace safety.
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 integrates premium Taiwanese 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. This configuration is specifically engineered to meet the rigorous demands of heavy-duty disk-type workpiece machining.
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.
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 slant bed 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 and larger-diameter workpiece machining.
Q Why does this machine use a 30° slant bed design?
The 30° slant bed layout offers multiple advantages: it improves operator visibility and accessibility, enables gravity-assisted chip removal to keep the work area clean, and enhances the machine's structural rigidity and anti-vibration performance through optimized internal ribbing and cast iron construction.
Q What is the repeatability accuracy of the X and Z axes?
Both the X-axis and Z-axis achieve a repeatability accuracy of ±0.0025 mm on both the NXX-46D and NXX-52D models. This is achieved through the combination of high-rigidity linear guideways, precision pre-tensioned ball screws, and direct-drive servo motors with flexible couplings.
Q What type of turret system does the machine use, and how fast is the tool change?
The standard configuration features a 160-10 Station Hydraulic Indexing Turret supporting up to 10 tools. Tool-to-tool indexing time is 0.5 seconds, with bi-directional shortest-path indexing. Optionally, a servo indexing turret is also available for even faster and more precise tool changes (0.3–0.5 sec).
Q How does the hydraulic system ensure stable and reliable operation?
The hydraulic system uses premium Taiwanese components including variable displacement pumps, hydraulic motors, and solenoid valves, combined with a high-efficiency air-cooled radiator. This ensures low-noise operation, precise oil temperature control, and reliable hydraulic movements throughout continuous heavy-duty machining cycles.
Q What safety and protection features are included with the machine?
The machine is equipped with a fully-enclosed aesthetic protection guard offering excellent waterproof and chip-proof performance.
