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 unobstructed 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 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 models?
The main differences lie in 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), tailstock spindle taper (MT4# vs MT5#), and total power consumption (11 Kw vs 14.5 Kw). The NXX-52D is designed for heavier-duty and larger-diameter machining tasks.
Q
What type of spindle bearing arrangement is used in these CNC lathes?
Both models use a high-precision cartridge-type spindle system with a 'front-three-rear-two' bearing arrangement - three imported precision-grade bearings at the front and two at the rear. This configuration ensures exceptional rotational accuracy, dynamic rigidity, and speed stability for heavy-duty cutting.
Q
What is the rapid traverse rate for X and Z axes?
Both the X-axis and Z-axis support a rapid traverse rate of up to 30 m/min on both the NXX-46D and NXX-52D models. This is achieved through high-rigidity linear guideways, precision pre-tensioned ball screws, and high-performance servo motors connected via flexible couplings.
Q
How many tools can the standard turret hold, and how fast is tool indexing?
The standard turret is a 160-10 Station Hydraulic Indexing Turret, capable of holding up to 10 tools. The tool-to-tool indexing time is 0.5 seconds, with bi-directional shortest-path indexing for maximum efficiency. Optional servo indexing turrets are also available.
Q
