NXX-46AL Slant Bed Gang Tool CNC Lathe from China: Quality Factory Supplies with Japanese Precision Components
Machine Structural Features
- This equipment centers on a heavy-duty, integral cartridge spindle for supreme accuracy and rigidity. Utilizing precision imported bearings configured as "three at the front, two at the rear" and direct servo motor drive, it ensures stable, high-speed performance.
- Rigidity begins with the base: a 45° inclined bed crafted from high-quality resin sand cast iron. Its reinforced ribbed design offers outstanding dampening and structural integrity, promoting user convenience and effective chip removal.
- High-speed linear motion is achieved using high-precision linear guides and pre-tensioned ball screws on the X and Z axes, directly connected to servo motors. A centralized automatic lubrication system supports high positioning precision, limits thermal deformation, and allows rapid traverses up to 30 m/min.
- A T-style gang tool post supports diverse tool setups and ensures fast tool indexing.
- The hydraulic station is built with Taiwanese components, including a variable pump, motor, and solenoid valves. An integrated air-cooler keeps operation quiet and maintains consistently low oil temperature.
- For safety and cleanliness, the machine features a stylish, fully enclosed cover with high water resistance. The sliding door moves smoothly for access and is protected by a safety interlock system.

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 — offer a continuous variable (CV) spindle speed range of 0–4,000 r/min, delivering flexible performance for a wide range of machining applications.
Q
What type of bed design does the NXX series use, and what are its advantages?
The NXX series features a 45° inclined bed made from high-quality resin sand cast iron with a reinforced ribbed structure. This design provides superior vibration dampening, excellent structural rigidity, easier chip removal, and improved operator ergonomics.
Q
How is positioning accuracy maintained on the X and Z axes?
The X and Z axes use high-precision linear guides and pre-tensioned ball screws directly connected to servo motors. A centralized automatic lubrication system minimizes thermal deformation and ensures a repeatability of ±0.0025 mm on both axes.
Q
What is the difference between the NXX-46A1 and NXX-46AL models?
The NXX-46AL is an enlarged variant offering a greater max. swing diameter (Φ420 mm vs. Φ360 mm), larger max. turning diameter (Φ400/Φ125 mm), extended axis travel, and a heavier machine weight of 2,800 kg, making it more suitable for larger disc and shaft workpieces.
Q
What tool post system is used, and how many tools can it hold?
The NXX series uses a T-style gang tool post that supports up to 8 tools. It accommodates OD tool sizes of 20×20 mm and boring bars up to Φ25 mm, enabling diverse machining operations with fast and accurate tool indexing.
Q
What safety and protection features are included with the machine?
The machine is equipped with a fully enclosed cover with high water resistance to protect against coolant and chips. The sliding door is designed for smooth, easy access and is secured by a safety interlock system to prevent accidental opening during operation.
