CNC Lathe NXX-46A1: Slant Bed Gang Tool from Top China Suppliers | Precision Factory Equipment
Machine Structural Features
1
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.
2
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.
3
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.
4
A versatile T-type gang tool post allows for multiple tool arrangements and enables very quick tool changes.
5
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.
6
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
Q1: What is the key difference between the NXX-36A1, NXX-46A1, and NXX-46AL models?
The main differences lie in spindle bore diameter, max swing diameter, bar capacity, and overall machine size. The NXX-36A1 features a Φ46mm bore and supports bar stock up to Φ35mm, while the NXX-46A1 and NXX-46AL both offer a larger Φ56mm bore and Φ45mm bar capacity. The NXX-46AL additionally provides a larger max swing diameter of Φ420mm and greater axis travel ranges, making it ideal for larger workpieces.
Q2: What type of spindle bearing arrangement does this machine use?
The machine uses a high-performance cartridge spindle with premium imported bearings arranged in a "three-front, two-rear" configuration. This arrangement is directly driven by a servo motor, ensuring exceptional precision, rigidity, and rotational stability during machining operations.
Q3: What is the maximum rapid traverse speed of the 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 through flexible couplings for fast and accurate positioning.
Q4: What tool post system is used, and how many tools can it hold?
All three models feature a T-type gang tool post configuration. It supports a maximum tool capacity of 8 pieces, with an OD tool size of 20×20mm and a maximum boring bar diameter of Φ25mm. This gang-type arrangement enables very quick tool changes and flexible multiple-tool setups.
Q5: What is the positioning repeatability of the machine axes?
Both the X and Z axes achieve a positioning repeatability of ±0.0025mm. The spindle radial and axial runout is ≤0.003mm, and machining flatness accuracy is ≤0.01mm over Φ100mm, ensuring consistent and high-precision results across production runs.
Q6: What safety and operational features does the machine enclosure provide?
The machine is equipped with a fully enclosed, streamlined guard featuring excellent sealing performance. The smooth-sliding door provides easy operator access and is fitted with a safety interlock system to protect the operator during machine operation, meeting standard industrial safety requirements.
