Crafted from high-strength HT300, the Oturn CNC Machine Twin Spindle Lathe is designed with a seamless one-piece structure to ensure unparalleled durability.Its structure is meticulouslycast and precisely made of iron, featuring a robust bed.The lathe incorporates a 30-degree step type flat rail design, optimized through finite element analysis for superior mechanical rigidity and stability. This ensures long-term accuracy, stable processing, and extended tool life. The stress relief treatment significantly enhances accuracy and stability. The high-strength roller rail design, coupled with a screw pre-tension drive system, improves response rigidity.
With the ability to process both ends of the workpiece simultaneously in one clamping, manual operations are minimized, output is maximized, and processes are streamlined. The second spindle allows full turning and can release workpieces during machining, significantly reducing cycle times.
1.The direct drive synchronous electric spindle device features a cutting-edge magnetic ring type incremental encoder. With positioning accuracy of 20 arc seconds and C-axis indexing accuracy of 40 arc seconds,
it effectively eliminates spindle vibrations while maintaining a nose-end deflection accuracy within 0.002mm. This drastically enhances the surface finish of workpieces.
The rear-mounted rotor simplifies installation and maintenance.
Equipped with a cooling system, the spindle motor maintains consistent working temperatures, minimizing thermal displacement. Having passed rigorous dynamic balance tests, the spindle system ensures precision retention, high rigidity, and efficiency. This allows the machine to perform both finishing and rough machining tasks, ideal for mass production of complex, high-finish products.
2. The high-rigidity integral servo power turret delivers rapid and precise tool changes. Utilizing a high-rigidity BMT interface for tool holder installation, and driven by a servo spindle motor, it ensures unparalleled performance.
3. Featuring THK linear guide rails and precision-ground ball screws, the machine ensures optimal precision and durability. The direct transfer shaft structure and double-anchor pre-relay method minimize thermal displacement, greatly enhancing machining accuracy. The high-rigidity, large-size, and heavy-duty linear slide rails maintain machine accuracy under impact, ensure smooth displacement, reduce noise, and extend the machine's service life.
4. Equipped with a standard FANUC system, the feed drive employs a high-performance FANUC servo motor.
5. The machine is designed with a perfect hydraulic and lubrication system, incorporating high-quality hydraulic pumps and valves to greatly reduce failure rates. It features a simple yet reliable system design.
6. Utilizing a Taiwan rotary chuck, oil cylinder, and an automatic chip removal device, the machine significantly reduces operator labor intensity, ensuring safe and efficient production. These components are programmable, and special fixtures can be accommodated.
