The two-axis lathe from Ningbo Oturn Machinery Co., Ltd is a marvel of modern engineering, designed to streamline operations and maximize output. With the ability to process both ends of a workpiece simultaneously in a single clamping, it significantly reduces manual labor, enhances productivity, and minimizes processes. Featuring a second spindle for full turning and efficient workpiece transfer, it cuts down cycle times remarkably. The lathe boasts a 30-degree inclined structure for high precision, super rigidity, and exceptional cutting stability. Built with a robust one-piece high-strength HT300 cast iron bed, it employs finite element analysis for outstanding mechanical rigidity and stability. This ensures long-term accuracy and enhances processing stability and tool life. Stress-relief treatment further improves accuracy stability. The high-strength roller linear rail design and screw pre-tension transmission system enhance rigidity performance, while its sleek, elegant appearance keeps it in line with contemporary trends.
Main features of this machine tool:
1. This machine incorporates a direct drive synchronous electric spindle device with a magnetic ring incremental encoder (sine and cosine) that offers positioning accuracy of 20 arc seconds and C-axis indexing accuracy of 40 arc seconds. This design effectively eliminates spindle vibration, maintaining nose deflection accuracy within 0.002MM. Enhanced surface finish of workpieces is ensured by a rear-mounted rotor for quick installation and maintenance. The spindle motor's cooling system mitigates thermal displacement, maintaining a stable operating temperature. Undergoing rigorous dynamic balance testing, the spindle system retains good accuracy, high rigidity, and high efficiency, making it suitable not only for finishing but also for rough machining and heavy cutting. Ideal for mass production of complex shapes and high smoothness products.
2. High rigidity integrated design servo power turret provides exceptional rapid and accurate tool changing performance. Paired with the power milling of a high-speed power axis, it ensures superior turning and milling combined processing capabilities. The tool holder uses a high-rigidity BMT installation interface, with the power transmission shaft driven by a servo spindle motor.
3. The machine tool is fitted with roller linear guides and ball screws that are heat-treated and precision-ground to guarantee the best accuracy and durability. Each axis features a direct transfer structure and double-anchor pre-relay method to minimize heat displacement, enhancing processing accuracy. High-rigidity, large-sized, heavy-duty linear slide rails maintain superb accuracy even under impact, with smooth, low-noise displacement to extend service life.
4. This machine offers a comprehensive hydraulic and lubrication system, utilizing top-quality hydraulic pumps, valves, and components to significantly reduce failure rates. The hydraulic and lubrication systems are designed for simplicity and reliability.
5. Featuring a Taiwan rotary chuck cylinder and optional automatic chip removal device, this machine greatly reduces operator labor intensity, ensuring safe and efficient production. All functional components are programmable and controllable, with various functions customizable to meet specific user requirements. A special fixture can be designed and installed accordingly.
