China Suppliers Factory NXX-52DEY: Advanced Slant-Bed Turn-Mill CNC Multi-Tasking Center with Servo Power Turret
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.

Frequently Asked Questions
Q
What is the difference between the NXX-46E, NXX-46EY, and NXX-52DEY models?
The NXX-46E is the base model with a servo power turret and ER25 live tooling, suitable for standard turning operations. The NXX-46EY adds Y-axis functionality (±55mm travel) and ER25/ER32+Y live tooling, enabling off-center milling and drilling. The NXX-52DEY is the most powerful variant, featuring a larger spindle bore (Φ62mm), higher main motor power (11kW), a hydraulic tailstock, and extended Z-axis travel (550mm), making it ideal for heavy-duty and long-shaft workpiece machining.
Q
What is the purpose of the 30° slant-bed design on these CNC lathes?
The 30° slant-bed design offers multiple advantages: it enhances structural rigidity through its high-strength cast iron construction with honeycomb-ribbed internals, improves vibration damping during heavy cutting, facilitates easier operator access for workpiece loading and tool changes, and — critically — allows chips to fall away from the cutting zone automatically, preventing chip accumulation that could damage workpieces or guideways.
Q
Can these machines perform milling, drilling, and tapping in addition to turning?
Yes. All three models are equipped with a servo power turret and live tooling capability (ER25 or ER32 collet systems). Combined with the spindle's C-axis function supporting 360° arbitrary indexing, the machines can perform side and end drilling, tapping up to M10 or M14, and milling operations. The NXX-46EY and NXX-52DEY further extend this capability with integrated Y-axis movement, enabling complete multi-surface machining in a single setup.
Q
What level of positioning accuracy can be expected from these machines?
These machines deliver high-precision performance across all axes. The X-axis and Z-axis repeatability accuracy is ±0.0025mm, spindle radial/axial run-out is ≤0.003mm, spindle flatness accuracy is ≤0.01mm over Φ100mm, and the live tooling spindle taper run-out is ≤0.006mm. This level of accuracy is achieved through the combination of precision pre-tensioned ball screws, heavy-duty linear guideways, and the intelligent centralized automatic lubrication system that minimizes thermal displacement errors.
Q
What is the role of the hydraulic tailstock on the NXX-52DEY model?
The hydraulic tailstock on the NXX-52DEY features an automatic programmable quill (Φ80mm diameter, 80mm travel, 5# Morse taper) controlled via hydraulic pressure with a body travel range of 480mm. It provides stable and precise workpiece support during the turning of long-shaft components, preventing deflection and vibration that would otherwise compromise surface finish and dimensional accuracy. Its programmable nature allows seamless integration into automated CNC cycles.
Q
How does the automatic lubrication system contribute to machine performance and longevity?
The intelligent centralized automatic lubrication system continuously delivers forced lubrication to all linear guideways and ball screws. By maintaining a consistent and optimal oil film on all moving surfaces, the system dramatically reduces friction and heat generation, which are primary causes of wear and thermal expansion errors. This results in superior and sustained positioning accuracy, extended component service life, reduced maintenance downtime, and the ability to sustain rapid traverse speeds of up to 30m/min reliably over long production runs.
