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 NXX-46BCY models?

The NXX-46BCY is the larger, more capable model featuring a greater max. swing over bed (Φ550mm vs Φ400mm), a larger Z-axis travel (360mm vs 260mm), a higher-capacity servo rotary turret (8–12 tools vs 4–5), and a higher total power capacity (15 Kw vs 10.5 Kw). The NXX-46CY uses gang tooling and is suited for smaller, high-speed precision parts, while the NXX-46BCY is optimized for larger, more complex multi-process workpieces.

Q What multi-tasking operations can the live tooling system perform?

The live tooling system, combined with the Y-axis and C-axis (360° spindle indexing), enables a wide range of operations including drilling, tapping, milling, and precision engraving on both the side and end faces of a workpiece. This allows complex multi-process parts to be completed in a single setup, significantly improving geometrical accuracy and reducing overall manufacturing cycle time.

Q How does the 30° slant bed design benefit machining performance?

The 30° slant bed, cast from a single piece of high-quality iron using resin sand precision casting, provides extreme mechanical rigidity and excellent vibration damping. The inclined structure optimizes the distribution of cutting forces, reduces thermal deformation, improves chip evacuation efficiency through gravity-assisted automatic chip removal, and enhances operator visibility and accessibility during setup and operation.

Q What positioning accuracy and repeatability can be expected from these machines?

Both the NXX-46CY and NXX-46BCY achieve a repeatability accuracy of ±0.0025mm on both the X and Z axes. Spindle radial and axial run-out is controlled to ≤0.003mm, live tool spindle taper run-out to ≤0.006mm, and spindle flatness accuracy to ≤0.01mm/Φ100. These specifications make the machines highly suitable for precision components requiring tight tolerances.

Q How is long-term accuracy and low thermal deformation maintained in the feed system?

The X and Z axes use high-precision linear guideways and precision pre-tensioned ball screws, with servo motors directly coupled via flexible couplings for zero-backlash transmission. A computerized automatic lubrication system provides forced-cycle lubrication to both the guideways and ball screws, effectively minimizing frictional heat generation and mechanical wear, thereby ensuring long-term stable positioning accuracy with minimal thermal deformation.

Q What safety features are incorporated into the machine enclosure?

The machines feature a fully enclosed guard system with a streamlined aesthetic design, offering superior sealing and waterproof performance. The sliding doors are engineered for smooth operation and are equipped with safety interlock devices that prevent the machine from operating when the door is open. This comprehensive safety design meets the high standards of modern manufacturing environments, protecting both operators and the machine from cutting fluid, chips, and other hazards.
