NXX-46A1 Slant Bed Gang Tool CNC Lathe - Quality from China Suppliers and Factory with Advanced Features
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 maximum spindle speed for the NXX-46A1 CNC lathe?
The NXX-46A1 features a spindle speed range of 0–4000 r/min with continuously variable (CV) speed control, powered by a 5.5 kW servo motor for consistent performance across all operations.
Q
What type of bed structure does this machine use, and what are its advantages?
The machine uses a 45-degree slant bed made of high-grade cast iron produced through resin sand molding. Its densely ribbed internal structure delivers superior stiffness, effective vibration damping, and efficient chip evacuation — all of which contribute to longer tool life and better surface finish quality.
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. This is made possible by high-rigidity linear guides, precision ball screws, and direct servo motor drives with flexible couplings.
Q
How many tools can the gang tool post hold, and what tool sizes are supported?
The T-type gang tool post supports up to 8 tools. It accommodates OD turning tools sized 20×20 mm and boring bars with a maximum diameter of Φ25 mm, enabling flexible multi-operation setups with very fast tool changeover.
Q
What is the difference between the NXX-36A1, NXX-46A1, and NXX-46AL models?
The key differences lie in machining capacity and size. The NXX-46AL offers the largest swing diameter (Φ420 mm), longest turning length (260 mm), and greatest machine weight (2800 kg). The NXX-46A1 provides a larger spindle bore (Φ56 mm) and bar capacity (Φ45 mm) compared to the NXX-36A1, while sharing the same footprint. All three models share the same 45° slant bed design and gang-type tooling system.
Q
What safety and maintenance features are included with this CNC lathe?
The machine includes a fully enclosed guard with excellent sealing and a smooth-sliding door fitted with a safety interlock to protect the operator during operation. A central lubrication system automatically services all guideways and ball screws. The hydraulic unit uses Taiwan-sourced components with an integrated air-cooling system to maintain stable oil temperatures and low noise levels.
