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 CNC lathe models?
The main 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), 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 designed for heavier and larger workpiece machining.
Q
What type of spindle bearing arrangement does the NXX-D series use?
The NXX-D series utilizes a 'front-three-rear-two' (triplex-front, duplex-rear) arrangement of imported precision-grade bearings within a cartridge-type spindle design. This configuration, combined with a direct-drive spindle servo motor, ensures exceptional rotational accuracy, dynamic rigidity, and speed stability for heavy-duty machining operations.
Q
What is the maximum rapid traverse rate for the X and Z axes?
Both the X-axis and Z-axis support a maximum rapid traverse rate of 30 m/min on both the NXX-46D and NXX-52D models. This is achieved through high-performance servo motors directly driving precision pre-tensioned ball screws via flexible couplings, supported by an intelligent centralized lubrication system.
Q
How fast is the turret tool change, and how many tools can it hold?
The standard 160-10 Station Hydraulic Indexing Turret supports up to 10 tools and achieves a tool-to-tool indexing time of 0.5 seconds. The machine also offers an optional servo indexing turret with rapid tool changes of 0.3–0.5 seconds, using bi-directional shortest-path indexing for maximum efficiency in heavy-duty disk-type workpiece machining.
Q
What is the repeatability accuracy of the NXX-D series CNC lathes?
Both the NXX-46D and NXX-52D achieve a repeatability accuracy of ±0.0025 mm on both the X-axis and Z-axis. Spindle radial/axial run-out is controlled to ≤ 0.003 mm, and spindle face flatness is ≤ 0.01 mm per Φ100 mm, reflecting the high precision engineering of these machines.
Q
What safety and protection features are included on the NXX-D series?
The NXX-D series is equipped with a fully-enclosed aesthetic protection guard that provides excellent waterproof and chip-proof performance. The smooth-operating sliding doors are integrated with safety interlocking protection to prevent accidental access during operation.
