Experience unparalleled efficiency with our two-axis Oturncnc Metal CNC Lathe Machine. Designed to process both ends of a workpiece in a single clamping, this machine revolutionizes manual operations, accelerates output, and streamlines processes. Its second spindle ensures comprehensive turning and seamlessly transfers workpieces during machining, drastically cutting cycle times. Showcasing an optimized 30-degree inclined structure, this lathe offers high precision, exceptional rigidity, and superior cutting stability. Crafted from one-piece, high-strength HT300 cast iron and subjected to finite element analysis, the lathe bed achieves extraordinary mechanical rigidity and stability. This design ensures long-term accuracy, enhances processing stability, and extends tool life. The high-strength roller linear rail and screw pre-tension design further boost rigidity, while the elegant appearance reflects modern 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 20 arc seconds positioning accuracy and a C-axis indexing accuracy of 40 arc seconds. This setup effectively eliminates spindle vibration, maintaining nose deflection within 0.002MM, thus enhancing the surface finish of the workpiece. The spindle includes a rear-mounted rotor for faster installation and maintenance, along with a cooling system to mitigate thermal displacement and maintain a constant operating temperature. The spindle system, tested for dynamic balance, guarantees exceptional accuracy retention, high rigidity, and efficiency, making the machine suitable for both finishing and rough machining, especially in the mass production of complex, high-smoothness products.
2. The high-rigidity integrated design servo power turret enhances rapid and precise tool changing capabilities. When combined with the power milling of a high-speed power axis, it delivers exceptional turning and milling integrated processing performance. The tool holder uses a high-rigidity BMT installation interface, while the power transmission shaft is driven by a servo spindle motor, ensuring peak performance.
3. Incorporating roller linear guides and heat-treated, precision-ground ball screws, this machine guarantees optimal accuracy and durability. Each axis employs a direct transfer structure and a double-anchor pre-relay method to minimize thermal displacement, significantly enhancing processing precision. The large-sized, heavy-duty linear slide rails withstand impacts while maintaining accuracy, offering smooth and low-noise displacement, which extends the machine's service life.
4. Our machine features a comprehensive hydraulic and lubrication system, utilizing high-quality hydraulic pumps, valves, and components to minimize failure rates. This reliable design ensures simplicity and efficiency, contributing to the machine's overall stability and performance.
5. The inclusion of a Taiwan rotary chuck cylinder and optional automatic chip removal device alleviates operator labor intensity, promoting safe and efficient production. These functional components are programmable and controllable, with various customizable functions and fixtures to meet users' specific requirements.
