China NXX-46AL Slant Bed Gang Tool CNC Lathe - Quality Suppliers and Factory Components for Precision Machining
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 — feature a continuously variable (CV) spindle speed range of 0–4,000 r/min, driven by a direct servo motor for stable high-speed performance.
Q
What type of bed design does this CNC lathe use, and what are its advantages?
The machine uses a 45° inclined bed made from high-quality resin sand cast iron with a reinforced ribbed structure. This design provides excellent vibration dampening, superior structural rigidity, convenient chip removal, and improved operator ergonomics.
Q
What is the positioning repeatability of the X and Z axes?
Both the X and Z axes achieve a repeatability of ±0.0025 mm across all three NXX models. This is supported by high-precision linear guides, pre-tensioned ball screws, and a centralized automatic lubrication system that minimizes thermal deformation.
Q
What is the difference between the NXX-46A1 and NXX-46AL models?
The NXX-46AL is the larger 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 compared to 2,500 kg for the NXX-46A1. Both share the same spindle motor power (5.5 Kw) and bore diameter (Φ56 mm).
Q
How does the hydraulic system maintain stable and quiet operation?
The hydraulic station is built with Taiwanese-sourced components including a variable pump, motor, and solenoid valves. An integrated air-cooler is incorporated to maintain consistently low oil temperatures, resulting in quieter operation and extended component service life.
Q
What safety features are included in the machine enclosure?
The machine is equipped with a fully enclosed, high water-resistance cover for cleanliness and operator protection. The smooth-sliding access door is fitted with a safety interlock system to prevent accidental contact with moving parts during operation.
