China NXX-46AL Slant Bed CNC Lathe: High Precision from Leading Suppliers and Factory
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 of the NXX series CNC lathes?
All three models in the NXX series — NXX-36A1, NXX-46A1, and NXX-46AL — offer a spindle speed range of 0–4,000 r/min with continuously variable (CV) speed control, making them suitable for a wide range of machining applications.
Q
What is the bed slant angle and why does it matter?
All NXX series machines feature a 45° inclined bed made from high-quality resin sand cast iron. This design improves chip evacuation, enhances structural rigidity, reduces vibration during cutting, and makes the machine more ergonomic and user-friendly.
Q
What is the positioning repeatability of the X and Z axes?
Both the X and Z axes achieve a positioning repeatability of ±0.0025 mm across all three models. This high precision is supported by high-precision linear guides, pre-tensioned ball screws, and a centralized automatic lubrication system.
Q
How many tools can the gang-type tool post hold?
The T-style gang tool post on all NXX series models supports up to 8 tools. It accommodates OD tools up to 20×20 mm and boring bars up to Φ25 mm in diameter, offering flexible tooling configurations for diverse machining tasks.
Q
What is the difference between the NXX-46A1 and NXX-46AL models?
The NXX-46AL is a larger variant with an increased max. swing diameter of Φ420 mm (vs. Φ360 mm), a higher max. turning diameter of Φ400 mm, greater X-axis travel of 850 mm, and larger overall dimensions of 2160×1650×1900 mm. It also weighs approximately 2,800 kg compared to 2,500 kg for the NXX-46A1.
Q
What safety and maintenance features does the machine include?
The machine is equipped with a fully enclosed cover offering high water resistance and a smooth-sliding door protected by a safety interlock system. The hydraulic station uses Taiwanese components with an integrated air-cooler to maintain low oil temperatures, while the centralized automatic lubrication system minimizes maintenance requirements and extends component service life.
