Product Description

Machine Structural Features
Core Spindle System
Heavy-Duty Integral Sleeve Spindle: Engineered for sustained heavy-cutting conditions, the spindle features a robust integral sleeve-type design. It integrates a "Three-Front, Two-Rear" configuration of imported precision bearings, powered by a rear-mounted servo motor. This combination delivers a consistent output of high speed, high precision, and exceptional rigidity.
Robust Bed Architecture: Utilizing a 30° slant-bed layout, the machine base is cast from high-quality resin-sand cast iron. The internal structure features a dense reinforcement ribbing system, delivering a superior combination of high rigidity, exceptional vibration damping, ergonomic operator convenience, and efficient automatic chip evacuation.
High-Speed Precision Feed System
High-Performance Linear Motion System: The X and Z axes are equipped with high-rigidity, heavy-duty linear guideways and precision pre-tensioned ball screws. Driven by direct-coupled servo motors and supported by an automatic forced lubrication system, the axes achieve rapid traverse speeds of up to 30 m/min while ensuring superior positioning accuracy and minimal thermal deformation.
Advanced Y-Axis Servo Power Turret: Equipped with a high-precision Y-axis box-way dual-side servo power turret, this system offers exceptional reliability and low failure rates. It supports rapid, nearest-path tool indexing for maximum efficiency. The turret disk is designed for flexible tool loading, unaffected by additional live tool attachments or workpiece dimensions, ensuring superior adaptability for diverse machining tasks.
Top-Tier Turn-Mill Capabilities
Integrated Multi-Tasking Machining Cell: This represents the ultimate highlight of the machine. By integrating rear-mounted servo main and sub-spindles, a Y-axis servo power turret, and imported precision gear-driven live tooling (for both radial and axial milling), we have built a complete, high-performance turn-mill unit.
Reliable Auxiliary Systems
Advanced Hydraulic & Safety Systems: The hydraulic station utilizes high-performance variable displacement pumps and core components from top-tier brands, equipped with an integrated air-cooling system. This ensures exceptionally quiet operation and precise oil temperature control even during extended shifts.
The machine features a stylish, fully enclosed protective housing that is completely waterproof and chip-proof. For maximum operator protection, the sliding doors are equipped with safety interlocks, ensuring a secure and user-friendly working environment.
This system significantly enhances machining rigidity, thermal stability, and indexing precision. It supports infinite C-axis indexing and dynamic workpiece handover (on-the-fly) between main and sub-spindles, effectively eliminating secondary setup errors. Complex geometries, large components, and parts with strict concentricity requirements can be completed — from turning and milling to drilling and tapping — in a single setup. This ensures maximum machining accuracy while drastically shortening the overall manufacturing cycle.

Frequently Asked Questions
Q What is the maximum bar capacity of the NXX-46ESY's main and sub-spindle?
The NXX-46ESY supports a maximum bar capacity of Φ45mm for both the main spindle and sub-spindle, with a bore diameter of Φ56mm for each. This makes it well-suited for a wide range of bar-fed turning applications.
Q What machining operations can be completed in a single setup on the NXX-46ESY?
Thanks to its integrated turn-mill unit featuring a Y-axis servo power turret, C-axis indexing, and live tooling (both radial and axial), the NXX-46ESY can complete turning, milling, drilling, and tapping all in a single setup — significantly reducing cycle time and eliminating secondary setup errors.
Q What is the rapid traverse speed of the X, Y, and Z axes?
All axes — X, Y, Z1, and Z2 — achieve a rapid traverse speed of 30 m/min. This is made possible by high-rigidity linear guideways, precision pre-tensioned ball screws, and direct-coupled servo motors, ensuring both speed and accuracy.
Q How does the NXX-46ESY ensure precision during main-to-sub-spindle workpiece handover?
The machine supports dynamic on-the-fly workpiece handover between the main and sub-spindles, with a handover concentricity of ≤0.01mm. This precision is maintained by the servo-controlled sub-spindle and the machine's robust slant-bed structure that minimizes thermal deformation.
Q What type of guideways does the NXX-46ESY use, and why does it matter?
The X and Z axes use high-rigidity, heavy-duty linear guideways, while the Y-axis turret employs a box-way dual-side design. Linear guideways provide superior speed and positioning accuracy, while the box-way turret offers enhanced rigidity and reliability — together ensuring excellent machining performance across diverse tasks.
