China NXX-46A1 CNC Lathe from Reliable Suppliers - Slant Bed Gang Tool Factory with Advanced Specifications
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 of the NXX-46A1 CNC lathe?
The NXX-46A1 features a spindle speed range of 0–4,000 r/min with continuously variable (CV) speed control, making it suitable for a wide range of turning applications from roughing to finishing.
Q
What type of tool post does this machine use, and how many tools can it hold?
All three models (NXX-36A1, NXX-46A1, NXX-46AL) use a T-type gang tool post configuration, supporting up to 8 tools. OD tool size is 20×20 mm, and the maximum boring bar diameter is Φ25 mm, enabling fast and flexible tool changes.
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 models. This high precision is enabled by high-rigidity linear guides and precision ball screws directly driven by servo motors with flexible couplings.
Q
What is the slant bed angle, and why does it matter?
The machine uses a 45-degree slant bed design made from high-grade cast iron with a densely ribbed structure. This angle improves chip evacuation, enhances operator ergonomics, provides superior structural rigidity, and effectively absorbs vibration during high-speed machining.
Q
What is the difference between the NXX-36A1, NXX-46A1, and NXX-46AL models?
The key differences lie in capacity and size: the NXX-46AL offers a larger max swing diameter (Φ420 mm vs Φ360 mm), greater turning length (260 mm vs 250 mm), larger bar capacity (Φ45 mm), and a bigger machine footprint (2160×1650×1900 mm, ~2800 kg). The NXX-36A1 has a smaller spindle bore (Φ46 mm) and lower spindle motor power (4 kW), making it ideal for lighter workpieces.
Q
How is the hydraulic system designed to ensure long-term stable operation?
The hydraulic power unit uses a variable displacement pump, motor, and solenoid valves sourced from Taiwan, combined with an integrated air-cooling system. This design maintains low operating noise, prevents oil overheating, and ensures consistent hydraulic performance over extended production runs.
