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
Q1: What is the difference between the NXX-46D and NXX-52D CNC lathe 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), total power consumption (11 Kw vs. 14.5 Kw), machine weight (3300 kg vs. 3500 kg), and tailstock spindle taper (MT4 vs. MT5). The NXX-52D is suited for heavier and larger-diameter workpieces.
Q2: What type of spindle bearing configuration is used in these CNC lathes?
The spindle system adopts a 'front-three-rear-two' arrangement of imported precision-grade bearings (triplex-front, duplex-rear). This high-rigidity cartridge-type design, combined with a direct-drive servo motor, delivers exceptional rotational accuracy and dynamic rigidity for heavy-duty machining applications.
Q3: What is the rapid traverse rate for the X and Z axes?
Both the X-axis and Z-axis support rapid traverse rates of up to 30 m/min. This is achieved through the combination of high-rigidity linear guideways, precision pre-tensioned ball screws, and high-performance servo motors connected via flexible couplings for backlash-free transmission.
Q4: How quickly can the turret change tools on the NXX-46D and NXX-52D?
Both models are equipped with a standard 160-10 Station Hydraulic Indexing Turret that supports rapid tool-to-tool indexing in 0.5 seconds. The turret features bi-directional shortest-path indexing and robust construction, making it ideal for high-efficiency, heavy-duty disk-type workpiece machining.
Q5: What repeatability accuracy can be expected from the X and Z axes?
Both the X-axis and Z-axis achieve a repeatability accuracy of ±0.0025 mm. This precision is maintained through the use of pre-tensioned ball screws, linear guideways, and an intelligent centralized forced lubrication system that also ensures thermal stability during continuous machining.
Q6: Is the machine bed design suitable for long-shift production environments?
Yes. The 30° slanted monolithic cast iron bed is reinforced with high-rigidity internal ribbing, offering outstanding anti-vibration performance and enhanced damping characteristics. The slanted layout also enables gravity-assisted automatic chip removal and provides ergonomic operator access, making it highly suitable for long-duration, high-volume production environments.
