The innovative two-axis CNC metal lathe is engineered to revolutionize your machining processes. With the capability to process both ends of a workpiece simultaneously within a single clamping, it significantly reduces manual interventions, enhances output, and streamlines operations. The second spindle ensures comprehensive turning and seamlessly transfers workpieces during machining, cutting down cycle times. Our machine boasts a 30-degree inclined design for superior precision, rigidity, and cutting stability. Crafted from high-strength HT300 cast iron using finite element analysis, the lathe bed ensures exceptional rigidity and stability, maintaining long-term accuracy and improving tool life. The roller linear rail design and pre-tensioned screw transmission system further enhance rigidity. Its elegant appearance embodies modern trends and functionality.
Main features of this machine tool:
1. Featuring a direct drive synchronous electric spindle device with a magnetic ring incremental encoder, this machine offers impressive positioning accuracy of 20 arc seconds and C-axis indexing accuracy of 40 arc seconds. The design effectively eliminates spindle vibration, maintaining nose deflection accuracy within 0.002MM. Equipped with a rear-mounted rotor for faster installation and maintenance, the spindle motor's cooling system suppresses thermal displacement, ensuring a constant operating temperature. Strict dynamic balance testing ensures high accuracy retention, rigidity, and efficiency, making it suitable for both fine finishing and heavy-duty rough machining. Ideal for mass production of complex, high-precision components.
2. The high-rigidity integrated design servo power turret facilitates rapid and precise tool changes. Combined with high-speed power axis milling, it offers superior turning and milling capabilities. The tool holder, installed using a high-rigidity BMT interface, is driven by a servo spindle motor, ensuring robust power transmission.
3. Equipped with roller linear guides and precision-ground ball screws, this machine guarantees optimal accuracy and longevity. The direct transfer axis structure and double-anchor pre-relay method minimize thermal displacement, enhancing processing accuracy. The robust, heavy-duty linear slide rails provide smooth, low-noise displacement and maintain impeccable accuracy even under impact, prolonging service life.
4. Featuring a comprehensive hydraulic and lubrication system, the machine uses high-quality hydraulic pumps and valves to significantly reduce failure rates. Designed for simplicity and reliability, the hydraulic and lubrication systems ensure smooth operation.
5. The machine includes a Taiwan rotary chuck cylinder and an optional automatic chip removal device, reducing operator labor and ensuring safe, efficient production. Programmable and controllable, these functional components can be tailored and installed to meet specific user needs, including specialized fixtures.
