China Suppliers Factory NXX-46A1 Slant Bed Gang Tool CNC Lathe with SYNTEC Control and Japanese Precision Bearings
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.
