Frequently Asked Questions
Q1: What is the key difference between the NXX-36A1, NXX-46A1, and NXX-46AL models?
The main differences lie in spindle bore diameter, bar capacity, swing diameter, and overall machine dimensions. The NXX-36A1 features a Φ46mm spindle bore and Φ35mm bar capacity, while the NXX-46A1 and NXX-46AL both offer a larger Φ56mm spindle bore and Φ45mm bar capacity. The NXX-46AL also provides a larger max swing diameter of Φ420mm and greater axis travel ranges.
Q2: What type of spindle bearing arrangement is used in these CNC lathes?
These machines use a high-performance cartridge spindle built with premium imported bearings arranged in a "three-front, two-rear" configuration. This arrangement ensures exceptional precision, rigidity, and rotational stability during demanding machining operations.
Q3: What is the maximum rapid traverse speed for the X and Z axes?
The Z-axis achieves a maximum rapid traverse speed of 30 m/min, while the X-axis reaches up to 24 m/min across all three models (NXX-36A1, NXX-46A1, and NXX-46AL). This is made possible by high-rigidity linear guides and precision ball screws directly driven by servo motors.
Q4: How does the slant bed design benefit machining performance?
The 45-degree slant bed, cast from high-grade iron using resin sand molding with a densely ribbed internal structure, delivers superior structural stiffness and effective vibration damping. This results in improved surface finish quality, extended tool life, and easier chip evacuation compared to flat-bed designs.
Q5: What is the positioning repeatability of these CNC lathes?
All three models achieve a positioning repeatability of ±0.0025mm on both the X and Z axes, with a spindle runout of ≤0.003mm (radial/axial) and a machining flatness accuracy of ≤0.01mm/Φ100mm — meeting the requirements of high-precision turning applications.
Q6: What tool holding system do these machines use, and how many tools can they accommodate?
All models are equipped with a versatile T-type gang tool post that supports up to 8 tools simultaneously. OD tooling accepts 20×20mm inserts, and the maximum boring bar diameter is Φ25mm. The gang-type configuration enables very quick tool changes, significantly reducing cycle times in production environments.
