The two-axis lathe is engineered to process both ends of the workpiece simultaneously in a single clamping, significantly simplifying manual operations, boosting output, and minimizing processing steps. The integration of a second spindle enables comprehensive turning functions and seamless workpiece transfers during machining, effectively cutting down cycle times. The machine's design boasts a 30-degree inclined structure, ensuring high precision, superior rigidity, and exceptional cutting stability. Constructed with a robust one-piece high-strength HT300 cast iron lathe bed and employing finite element analysis, the machine excels in mechanical rigidity and long-term stability. This design retains reliable accuracy, enhances processing stability, prolongs tool life, and benefits from stress relief treatment for improved accuracy stability. The high-strength roller linear rail design and screw pre-tension transmission system further enhance rigidity performance. Coupled with a sleek, modern appearance, this machine aligns perfectly with contemporary trends.
Main features of this machine tool:
1. The direct drive synchronous electric spindle device features a magnetic ring incremental encoder (sine and cosine) with positioning accuracy of 20 arc seconds and C-axis indexing accuracy of 40 arc seconds. This setup effectively eliminates spindle vibration, maintaining nose deflection accuracy within 0.002MM and improving the workpiece's surface finish. The rear-mounted rotor enables fast installation and maintenance, while the spindle motor's cooling system suppresses thermal displacement, ensuring a constant spindle operating temperature. Undergoing stringent dynamic balance testing, the spindle system boasts excellent accuracy retention, high rigidity, and efficiency, making the machine capable of both fine finishing and heavy-duty rough machining. This is particularly advantageous for high-volume production of complex and highly smooth products.
2. The high rigidity integrated design servo power turret enhances rapid and precise tool changing performance. When combined with the high-speed power axis's power milling, it provides outstanding turning and milling capabilities. The tool holder employs a high-rigidity BMT installation interface, and the power transmission shaft is driven by a servo spindle motor.
3. The machine features roller linear guides and ball screws that are heat-treated and precision-ground to ensure optimal accuracy and durability. Each axis incorporates a direct transfer axis structure and a double-anchor pre-relay method, minimizing heat displacement and significantly improving processing precision. The high-rigidity, large-sized, heavy-duty linear slide rails maintain their accuracy even under impact, with smooth and low-noise displacement that extends service life.
4. Equipped with a comprehensive hydraulic and lubrication system, this machine utilizes high-quality hydraulic pumps, valves, and other components to substantially reduce failure rates. The hydraulic and lubrication systems are designed for simplicity and reliability.
5. Featuring a Taiwan rotary chuck cylinder and an optional automatic chip removal device, the machine significantly reduces operator labor intensity, promoting safe and efficient production. These functional components are fully programmable, with various functions customizable and installable according to user-specific requirements.
