China CNC Lathe NXX-46A1: Slant Bed Gang Tool from Reliable Suppliers and Factory
Machine Structural Features
Designed for demanding applications, this machine integrates a high-performance cartridge spindle. Built with premium imported bearings in a "three-front, two-rear" arrangement and powered directly by a servo motor, it delivers exceptional precision, rigidity, and rotational stability.
Its foundation is a robust 45-degree slant bed made of high-grade cast iron via resin sand molding. The densely ribbed structure provides superior stiffness and effective vibration absorption, while also facilitating easy operation and efficient chip flow.
For rapid and accurate axis movement, the X and Z axes employ high-rigidity linear guides and precision ball screws. These are directly driven by servo motors through flexible couplings, with a central lubrication system servicing all guideways and screws. This design achieves high positioning accuracy, minimizes thermal effects, and enables fast traverse speeds of up to 30 m/min.
A versatile T-type gang tool post allows for multiple tool arrangements and enables very quick tool changes.
The hydraulic power unit incorporates a variable displacement pump, motor, and solenoid valves sourced from Taiwan. Its integrated air-cooling system maintains low operating noise and stable, cool oil temperatures.
Completing the package is a streamlined, fully enclosed guard with excellent sealing. The smooth-sliding door ensures easy access and is fitted with a safety interlock for operator protection.

Frequently Asked Questions
Q
What is the difference between the NXX-36A1, NXX-46A1, and NXX-46AL models?
The three models differ primarily in their spindle bore diameter, max swing diameter, bar capacity, axis travel ranges, and machine weight. The NXX-36A1 is the most compact, while the NXX-46AL offers the largest swing diameter (Φ420mm) and longest Z-axis travel (330mm), making it suitable for larger workpieces.
Q
What type of spindle bearing arrangement is used in these CNC lathes?
These machines use premium imported bearings in a "three-front, two-rear" arrangement within a high-performance cartridge spindle. This configuration ensures exceptional precision, rigidity, and rotational stability during demanding machining operations.
Q
What is the maximum rapid traverse speed for the X and Z axes?
The Z-axis achieves a maximum rapid traverse speed of 30 m/min, while the X-axis reaches up to 24 m/min. Both axes use high-rigidity linear guides and precision ball screws directly driven by servo motors for fast and accurate positioning.
Q
What is the positioning repeatability of the NXX series CNC lathes?
All three models achieve a positioning repeatability of ±0.0025mm on both the X and Z axes, with spindle runout of ≤0.003mm (radial/axial) and machining flatness accuracy of ≤0.01mm/Φ100. This ensures consistent high-precision results across production runs.
Q
What type of tool post does the NXX series use, and how many tools can it hold?
The NXX series is equipped with a T-type gang tool post that supports up to 8 tools. It accommodates OD tools of 20×20mm and boring bars up to Φ25mm in diameter, enabling versatile machining operations with very quick tool changes.
Q
What safety and operator-protection features are included on these machines?
Each machine features a streamlined, fully enclosed guard with excellent sealing performance. The smooth-sliding access door is fitted with a safety interlock system to protect the operator during machining. The hydraulic unit also incorporates an integrated air-cooling system to maintain stable and safe operating temperatures.
