The advanced two-axis lathe is engineered to handle both ends of the workpiece simultaneously within a single clamping operation. This sophisticated feature streamlines manual activities, amplifies output, and minimizes operational steps. The innovative second spindle facilitates full turning and seamlessly transitions workpieces during machining, thus significantly cutting down cycle times. The machine boasts an optimized 30-degree inclined structural design, endowed with unparalleled precision, robust rigidity, and superior cutting stability. Constructed from one-piece high-strength HT300 cast iron, the lathe bed harnesses finite element analysis for maximum mechanical rigidity and stability. It ensures long-term reliability, enhances processing stability, and extends tool lifespan through stress relief treatment. The high-strength roller linear rail design, combined with a screw pre-tension transmission system, elevates rigidity performance, while its sleek and sophisticated appearance aligns with contemporary design trends.
Main features of this machine tool:
1. Equipped with a direct-drive synchronous electric spindle device featuring a magnetic ring incremental encoder (sine and cosine) with a positioning accuracy of 20 arc seconds and a C-axis indexing accuracy of 40 arc seconds. The spindle's vibration is effectively eliminated, ensuring a nose deflection accuracy within 0.002MM. This enhances the surface finish of workpieces, with a rear-mounted rotor for quicker installation and maintenance. A cooling system for the spindle motor mitigates thermal displacement effects, ensuring a consistent operating temperature. After undergoing rigorous dynamic balance testing, the spindle system retains excellent accuracy, high rigidity, and efficiency, enabling the machine to perform both finishing and rough machining tasks. It is particularly adept at mass production of complex shapes with high smoothness.
2. Featuring a high rigidity integrated design servo power turret, this machine excels in rapid and precise tool changing performance. When paired with the high-speed power axis for power milling, it delivers exceptional combined turning and milling capabilities. The tool holder uses a high-rigidity BMT installation interface, driven by a servo spindle motor for superior power transmission.
3. The machine tool is equipped with roller linear guides and precision-ground ball screws that have been heat-treated to ensure optimal accuracy and longevity. Each axis employs a direct transfer structure and a double-anchor pre-relay method to minimize thermal displacement, significantly enhancing processing precision. The high-rigidity, large-sized, heavy-duty linear slide rails maintain their accuracy even under impact, while ensuring smooth, low-noise displacement, thus prolonging the machine's service life.
4. Users benefit from a comprehensive hydraulic and lubrication system, incorporating premium hydraulic pumps, valves, and other components to substantially reduce failure rates. The system's design emphasizes simplicity and reliability.
5. The machine features a Taiwan rotary chuck cylinder and an optional automatic chip removal device, significantly reducing operator labor intensity and achieving safe, efficient production. These functional components are programmable and controllable, with various functions customizable to meet specific user requirements, including special fixtures.
