Frequently Asked Questions
Q
What is the maximum spindle speed for the NXX series CNC lathes?
All three models in the NXX series — NXX-36A1, NXX-46A1, and NXX-46AL — feature a continuously variable (CV) spindle speed range of 0–4000 r/min, enabling flexible machining for a wide variety of materials and part geometries.
Q
What type of tool post does the NXX series use, and how many tools can it hold?
The NXX series uses a T-type gang tool post configuration. Each machine can hold up to 8 tools, supporting a variety of tooling combinations. OD tool size is 20×20 mm and the maximum boring bar diameter is Φ25 mm.
Q
What is the positioning repeatability of the NXX series CNC lathes?
The NXX series achieves a positioning repeatability of ±0.0025 mm on both the X-axis and Z-axis across all three models, ensuring high-precision machining consistency for demanding applications.
Q
What is the bed slant angle, and why is it important?
All NXX series models feature a 45° slant bed design. This configuration improves chip evacuation, enhances rigidity, and provides a more ergonomic operating position for the operator. The bed is manufactured from high-quality cast iron with a compact ribbed structure for excellent vibration damping.
Q
What is the maximum bar capacity and spindle bore diameter for each model?
