The two-axis lathe from Ningbo Oturn Machinery Co., Ltd. is a marvel of technological advancement. It effortlessly processes both ends of a workpiece simultaneously in a single clamping, drastically simplifying manual operations, boosting output, and minimizing processes. The innovative second spindle facilitates full turning and seamless workpiece transfer during machining, significantly reducing cycle times. Designed with a 30-degree inclined structure, this machine boasts exceptional precision, unparalleled rigidity, and superb cutting stability. The robust lathe bed, crafted from one-piece high-strength HT300 cast iron, is enhanced through finite element analysis. This ensures outstanding mechanical rigidity and stability, maintaining long-term reliable accuracy, enhancing processing stability, extending tool life, and improving accuracy stability through stress relief treatment. Its high-strength roller linear rail design, combined with a screw pre-tension transmission system, elevates rigidity performance. The machine's simple and elegant appearance reflects contemporary design trends, making it a standout in any workshop.
Remarkable Main Features of this Machine Tool:
1. Cutting-edge direct drive synchronous electric spindle device with a magnetic ring incremental encoder (sine and cosine) ensures a positioning accuracy of 20 arc seconds and a C-axis indexing accuracy of 40 arc seconds. This mechanism effectively eliminates spindle vibration, maintaining a nose deflection accuracy within 0.002MM, and greatly improves the surface finish of the workpiece. The rear-mounted rotor design allows for quicker installation and maintenance. Equipped with a cooling system, the spindle motor suppresses thermal displacement, ensuring a constant operating temperature. Rigorous dynamic balance testing of the spindle system guarantees excellent accuracy retention, high rigidity, and high efficiency, enabling the machine to handle both finishing and rough machining, as well as heavy cutting. Perfectly suited for mass production of complex shapes and high-smoothness products.
2. The high-rigidity integrated design servo power turret enhances rapid and precise tool changing, while the high-speed power axis milling capability delivers exceptional combined turning and milling performance. Mounted using a high-rigidity BMT installation interface, the tool holder ensures superior stability. The power transmission shaft is driven by a servo spindle motor, contributing to the machine's overall high efficiency.
3. Roller linear guides and ball screws are key features of this machine tool. Heat-treated and precision-ground ball screws guarantee optimal accuracy and durability. Each axis employs a direct transfer structure and a double-anchor pre-relay method to minimize thermal displacement, significantly boosting processing accuracy. The high-rigidity, large-sized, heavy-duty linear slide rails maintain accuracy under impact, ensuring smooth, low-noise displacement and extending the machine's service life.
4. Comprehensive hydraulic and lubrication systems enhance user convenience, incorporating high-quality hydraulic pumps, valves, and components to minimize failure rates. These systems are designed for simplicity and reliability, ensuring efficient and trouble-free operation.
5. Featuring a Taiwan rotary chuck cylinder and an optional automatic chip removal device, this machine greatly reduces operator labor intensity while ensuring safe and efficient production. The versatile functional components can be programmed and controlled, and customized functionalities can be designed and installed based on specific user needs, including special fixtures.
