The two-axis Mitsubishi CNC Metal Lathe with A2-6 Spindle and 8-Inch Chuck is a marvel of engineering, designed to process both ends of a workpiece simultaneously in one clamping. This innovative feature drastically reduces manual operations, increases productivity, and minimizes process complexity. The inclusion of a second spindle enables comprehensive turning and seamless workpiece transfer during machining, significantly cutting cycle times. Its optimized 30-degree inclined structure offers unmatched precision, rigidity, and cutting stability. Crafted from one-piece high-strength HT300 cast iron, the lathe bed benefits from finite element analysis for superior mechanical rigidity and stability. It ensures long-term accuracy, enhanced processing stability, and extended tool life. The high-strength roller linear rail and screw pre-tension design boost rigidity performance while the sleek appearance aligns with contemporary trends.
Main features of this machine tool:
1. The machine boasts a direct-drive synchronous electric spindle with a magnetic ring incremental encoder providing positioning accuracy of 20 arc seconds and C-axis indexing accuracy of 40 arc seconds. This effectively eliminates spindle vibration, maintaining nose deflection accuracy within 0.002MM. It improves workpiece surface finish, and the rear-mounted rotor facilitates faster installation and maintenance. The spindle motor's cooling system minimizes thermal displacement, ensuring constant operating temperature. Rigorous dynamic balance testing of the spindle system ensures excellent accuracy retention, high rigidity, and efficiency, making it ideal for both finishing and rough machining. It is especially suited for mass production of complex, high-smoothness products.
2. The high-rigidity integrated design servo power turret enhances rapid and precise tool changing performance. Coupled with high-speed power axis milling, it achieves superior combined turning and milling capabilities. The tool holder features a high-rigidity BMT installation interface, driven by a servo spindle motor.
3. Equipped with roller linear guides and precision-ground ball screws, the machine ensures optimal accuracy and durability. Each axis features a direct transfer structure and double-anchor pre-relay method, minimizing thermal displacement and significantly enhancing processing accuracy. High-rigidity, heavy-duty linear slide rails maintain accuracy under impact, offering smooth, low-noise displacement and extended service life.
4. A complete hydraulic and lubrication system with high-quality components such as hydraulic pumps and valves greatly reduces the failure rate. The design prioritizes simplicity and reliability.
5. The machine incorporates a Taiwan rotary chuck cylinder and an optional automatic chip removal device, significantly reducing operator labor intensity while ensuring safe and efficient production. Programmable control of these components allows for customization to meet specific user requirements.
