Product Description

Structural Features
Core Spindle System

It adopts an integrated sleeve spindle structure, featuring imported high-precision spindle bearings in a "three-front, two-rear" layout, driven directly by a high-response spindle servo motor. This design is engineered to achieve three core objectives: ultra-high rotational accuracy, superior rigidity for heavy-duty cutting, and exceptionally stable speed performance at high RPMs, laying a solid foundation for the machine's processing capabilities.

High-Rigidity Bed Structure

The machine base is manufactured from a single-piece iron casting featuring a 30° slant bed design. By utilizing high-quality cast iron combined with resin sand precision casting processes and constructing a dense internal network of reinforcing ribs, the bed achieves both extreme mechanical rigidity and excellent vibration-damping characteristics. The slanted structure not only optimizes the force distribution of the machine but also provides intuitive operational convenience and high-efficiency automatic chip removal.

High-Speed Precision Feed Unit

The X and Z axes feature high-rigidity, high-precision linear guideways and precision pre-tensioned ball screws. The servo motors are directly coupled to the ball screws via flexible couplings, ensuring zero-backlash power transmission. Equipped with a computerized automatic lubrication system, the guideways and ball screws receive forced-cycle lubrication, effectively controlling frictional heat and wear. This guarantees the system's long-term stable positioning accuracy (with minimal thermal deformation) and achieves a rapid traverse rate of up to 30 m/min.

High-Efficiency & Reliable Hydraulic or Servo Rotary Turret

The hydraulic station incorporates premium brand variable displacement pumps, motors, and solenoid valves, integrated with an air-cooled radiator to ensure low-noise and low-temperature-rise operation. The tooling system offers multiple configurations, including hydraulic or servo rotary turrets, both engineered for rapid tool changes and shortest-path tool selection. Its universal design ensures that the tool capacity is not restricted by additional functional modules (such as live tooling) or large-scale workpieces, providing exceptional adaptability.

Advanced Multi-Tasking & Engraving Functions

The machine is equipped with a servo-driven spindle and an expanded live tooling system featuring Y-axis functionality for both radial and axial operations. Utilizing imported precision gear transmission, the live tools offer superior rigidity, low noise, and high operational accuracy. This configuration unlocks powerful turn-mill and engraving capabilities: while the spindle achieves 360° arbitrary indexing (C-axis), the live tooling performs complex drilling, tapping, milling, and precision engraving on both the side and end faces. Consequently, complex multi-process parts can be completed in a single setup, maximizing geometrical tolerance integrity and significantly shortening the overall manufacturing cycle.

Safe and Aesthetic Full Enclosure

The entire machine features a fully enclosed guard system with a streamlined, aesthetic design and superior sealing and waterproof performance. The sliding doors operate smoothly and are equipped with safety interlock devices, providing comprehensive protection while ensuring maximum operational safety and convenience. This design strictly adheres to the high standards of modern factories regarding both production environments and safety regulations.

Frequently Asked Questions
Q: What is the key difference between the NXX-46CY and the NXX-46BCY models?

The NXX-46BCY features a larger max. swing over bed (Φ550mm vs Φ400mm), greater Z-axis travel (360mm vs 260mm), a higher-capacity servo rotary turret (8–12 tools vs gang tooling with 4–5 tools), and more powerful servo motors (2.4Kw vs 1.3Kw), making it better suited for larger and more complex workpieces requiring multi-axis machining.

Q: What is the advantage of the 30° slant bed design on these CNC lathes?

The 30° slant bed design optimizes the distribution of cutting forces across the machine structure, resulting in superior rigidity and vibration damping. It also improves chip evacuation efficiency through gravity-assisted chip flow, enhances operator ergonomics and visibility, and contributes to longer machine life and better surface finish quality on machined parts.

Q: Can these machines perform milling and engraving operations in addition to turning?

Yes. Both models are equipped with a live tooling system featuring Y-axis functionality for radial and axial operations, combined with a C-axis (360° arbitrary spindle indexing). This enables complex turn-mill operations including drilling, tapping, milling, and precision engraving on both the side and end faces of a workpiece — all in a single setup.

Q: How does the automatic lubrication system benefit long-term machine performance?

The computerized automatic lubrication system delivers forced-cycle lubrication to all linear guideways and ball screws. This effectively controls frictional heat generation and mechanical wear, ensuring minimal thermal deformation and stable long-term positioning accuracy. It also reduces maintenance requirements and extends the service life of precision components significantly.

Q: What spindle accuracy can be expected from the NXX-46CY / NXX-46BCY?

Both models achieve a spindle radial and axial run-out of ≤0.003mm, a spindle flatness accuracy of ≤0.01mm/Φ100, and a live tool spindle taper run-out of ≤0.006mm. The X and Z axis repeatability accuracy is ±0.0025mm, making these machines highly suitable for precision parts manufacturing.

Q: What safety features are included with the full enclosure guard system?

The fully enclosed guard system features a streamlined aesthetic design with superior sealing and waterproof performance. The sliding doors are engineered for smooth operation and are fitted with safety interlock devices that prevent machine operation when the guard is open. This comprehensive protection system complies with modern factory safety standards and ensures a safe, clean working environment for operators.
