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 featuring a servo power turret and ER25 live tooling without Y-axis functionality. The NXX-46EY adds integrated Y-axis travel (110mm) and ER25/ER32+Y live tooling for enhanced multi-surface machining. The NXX-52DEY is the most powerful variant, offering a larger spindle bore (Φ62mm), higher main motor power (11kW), longer Z-axis travel (550mm), and a hydraulic tailstock — ideal for heavy-duty and long-shaft workpiece machining.
Q
What makes the 30° slant-bed design advantageous for CNC turning?
The 30° slant-bed, cast from high-strength iron using the precision resin-sand process, provides exceptional static and dynamic rigidity thanks to its internal honeycomb-ribbed structure. This geometry improves chip evacuation, enhances operator access to the workpiece, and reduces vibration during heavy-duty cutting — all contributing to better surface finish and longer tool life.
Q
Can these machines perform milling and drilling operations in addition to turning?
Yes. All three models are equipped with a servo power turret and live tooling (ER25 or ER32), enabling side and end drilling, tapping, and milling operations. With the spindle's 360° arbitrary C-axis indexing capability, complex multi-surface features can be completed in a single setup, significantly reducing cycle times and handling.
Q
What positioning and repeatability accuracy can these machines achieve?
The machines achieve a repeatability accuracy of ±0.0025mm on both X and Z axes, spindle radial/axial run-out of ≤0.003mm, spindle flatness accuracy of ≤0.01mm/Φ100, and live tooling spindle taper run-out of ≤0.006mm. These specifications make them suitable for high-precision component manufacturing across aerospace, automotive, and medical industries.
Q
How does the automatic lubrication system contribute to machine performance?
The intelligent centralized automatic lubrication system continuously delivers forced lubrication to all guideways and ball screws. This maintains an optimal oil film that reduces friction and heat generation, minimizes thermal displacement errors, and helps sustain rapid traverse speeds of up to 30m/min. The result is consistent machining accuracy and extended service life of critical motion components.
Q
Is the NXX-52DEY suitable for long-shaft workpiece machining?
Yes. The NXX-52DEY is specifically designed for long-shaft workpieces. It is equipped with a hydraulic tailstock featuring an automatic programmable quill (Φ80mm diameter, 80mm travel, 5# taper) with 480mm body travel. This provides stable support and high-precision alignment, ensuring accurate and repeatable results when turning long or heavy shaft components.
