CNC Lathe NXX-46AL: Slant Bed Design with Premium China Suppliers and Factory 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 for the guides and screws 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 — feature a continuously variable (CV) spindle speed range of 0 to 4,000 r/min, driven directly by a servo motor for stable high-speed performance.
Q
What type of bed design does the NXX series use, and what are the advantages?
The NXX series uses a 45° inclined bed made from high-quality resin sand cast iron with a reinforced ribbed structure. This design delivers outstanding vibration dampening, excellent structural rigidity, easy chip removal, and improved operator ergonomics.
Q
What are the rapid traverse speeds for the X and Z axes?
The X-axis supports a rapid traverse speed of 24 m/min, while the Z-axis achieves up to 30 m/min. Both axes use high-precision linear guides and pre-tensioned ball screws directly connected to servo motors for fast and accurate positioning.
Q
How many tools can the gang tool post hold, and what tool sizes are supported?
The T-style gang tool post supports a maximum of 8 tools. The OD tool size is 20×20 mm, and the maximum boring bar diameter is Φ25 mm. This configuration enables diverse tool setups and fast tool indexing.
Q
What positioning repeatability can be expected from the NXX series?
All NXX series models achieve a positioning repeatability of ±0.0025 mm on both the X and Z axes. The centralized automatic lubrication system further supports this precision by limiting thermal deformation during operation.
Q
What safety and enclosure features does the NXX series offer?
The NXX series features a fully enclosed, high water-resistant cover with a smooth-sliding access door. The door is equipped with a safety interlock system to protect operators during machining. The hydraulic station also incorporates an integrated air-cooler to maintain low oil temperature and quiet operation.
