Product Description

Structural Features
Engineered for High-Rigidity & Precision Multi-Tasking

To meet the rigorous demands of modern precision manufacturing for high rigidity, efficiency, and multi-tasking capabilities, this machine has undergone comprehensive reinforcement of its critical components.

High-Rigidity Sleeve Spindle System:

Optimized for heavy-duty conditions, the core features an integrated sleeve-type spindle design. It is equipped with imported ultra-precision bearings in a "three-front, two-rear" configuration, driven directly by a high-response spindle servo motor. This synergy guarantees unparalleled accuracy retention, structural rigidity, and rotational stability during high-speed, heavy-load cutting operations.

30° Slant-Bed Foundation:

The machine base is a 30° slant-bed made of high-strength cast iron, formed via the precision resin-sand casting process. The interior is reinforced with a dense, honeycomb-ribbed structure, which provides extraordinary static and dynamic rigidity while offering superior vibration damping. This design not only facilitates easier workpiece clamping and tool access but also ensures the unobstructed automatic evacuation of chips.

High-Precision Feed System:

For the motion system, the X and Z axes utilize heavy-duty linear guideways known for high rigidity and precision. These are paired with precision pre-tensioned ball screws, directly coupled to the servo motors via flexible couplings to eliminate transmission loss.

Intelligent Centralized Auto-Lubrication Provides continuous forced lubrication to guideways and ball screws, achieving superior positioning accuracy, minimizing thermal displacement errors, and enabling rapid traverse speeds of up to 30 m/min. Significantly reduces friction and heat generation for consistent high-speed performance.
Premium Hydraulic System Integrates variable displacement pumps, hydraulic motors, and solenoid valves from renowned brands. Equipped with a high-efficiency air cooler to minimize noise and maintain stable operating temperature, guaranteeing dependable power during intensive production cycles.
Advanced Multi-Tasking & Heavy-Duty Milling Capability

The machine is equipped with a high-performance servo spindle and a servo power turret with integrated Y-axis functionality, offering the flexibility to mount side-milling and end-milling live heads. The live tool transmission utilizes imported high-precision gear sets, achieving a perfect harmony of high rigidity, low noise, and extreme precision.

This powerful drive and execution system significantly bolsters the machine's overall structural rigidity, process stability, and indexing accuracy during multi-surface machining, delivering formidable heavy-duty cutting performance. With the spindle supporting 360° arbitrary indexing, the machine integrates side and end drilling, tapping, and milling functions. This enables the complete processing of complex, large-scale, and long-shaft workpieces in a single setup, making it the ideal choice for achieving high-level process concentration.

Hydraulic Tailstock Features an automatic programmable quill controlled via hydraulic pressure. Designed with superior rigidity and ease of operation, it provides stable support and high-precision alignment — the ideal solution for precision turning of long-shaft workpieces.
Full-Enclosure Safety Guard Features an elegantly designed full-enclosure guard with excellent sealing and waterproof performance. Sliding doors are engineered for smooth operation and integrated with a safety interlock protection system, ensuring a clean working environment and comprehensive operator protection.

Frequently Asked Questions
What is the difference between the NXX-46E, NXX-46EY, and NXX-52DEY models?
The NXX-46E is the base model featuring a servo power turret without Y-axis functionality. The NXX-46EY adds integrated Y-axis capability and a larger swing diameter (Ø 480mm), enabling more complex multi-surface machining. The NXX-52DEY is the most powerful variant, offering the largest machining length (400mm), highest main motor power (11 Kw), a hydraulic tailstock, and a total power capacity of 24 Kw — ideal for heavy-duty, long-shaft workpiece processing.
What type of spindle bearing configuration does this machine use?
The machine features an integrated sleeve-type spindle system equipped with imported ultra-precision bearings in a "three-front, two-rear" configuration. This design is directly driven by a high-response spindle servo motor, ensuring exceptional accuracy retention, structural rigidity, and rotational stability even under high-speed, heavy-load cutting conditions.
What is the maximum rapid traverse speed achievable on this CNC turning center?
The machine achieves rapid traverse speeds of up to 30 m/min on both the X and Z axes (on the NXX-46EY and NXX-52DEY models). The Y-axis on the NXX-46EY reaches 30 m/min, while on the NXX-52DEY it operates at 12 m/min. These speeds are supported by the intelligent centralized automatic lubrication system that minimizes friction and thermal displacement.
Does this machine support live tooling and milling operations?
Yes. All three models are equipped with a servo power turret supporting live tooling (ER25 or ER32 collet types). The NXX-46EY and NXX-52DEY additionally feature Y-axis integration, enabling side and end drilling, tapping, and milling. Live tool speeds range from 3,000 to 6,000 r/min, with motor power up to 3.7 Kw (NXX-46E) and a combined 3.1+0.75+2.4 Kw on the EY models.
What is the repeatability accuracy of the X and Z axes?
All three models achieve a repeatability accuracy of ±0.0025 mm on both the X and Z axes. The spindle run-out (radial/axial) is ≤ 0.003 mm, and the live tooling spindle taper run-out is ≤ 0.006 mm, ensuring consistent high-precision results across production batches.
Is the machine suitable for processing long-shaft workpieces?
Yes. The NXX-52DEY model is specifically designed for long-shaft workpiece processing, featuring a hydraulic tailstock with a Ø 80mm quill, 80mm quill travel, 480mm body travel, and a No. 5 Morse taper. Combined with 360° arbitrary spindle indexing and integrated milling/drilling capabilities, it enables complete complex workpiece processing in a single setup.
