The unparalleled two-axis lathe revolutionizes efficiency by processing both ends of the workpiece simultaneously in a single clamping, streamlining operations, boosting output, and minimizing procedures. The integration of a second spindle allows for comprehensive turning and seamless workpiece transfer during machining, substantially cutting down cycle times. Featuring an optimized 30-degree inclined structure, this machine promises exceptional precision, superior rigidity, and remarkable cutting stability. The robust, one-piece high-strength HT300 cast iron lathe bed, reinforced through finite element analysis, ensures extraordinary mechanical strength and stability, maintaining long-term, reliable accuracy and extended tool life. The high-strength roller linear rail and screw pre-tensioned transmission system bolster rigidity and performance. With a sleek and modern design, this machine exemplifies both aesthetic appeal and cutting-edge engineering.
Main features of this machine tool:
1. Equipped with a direct drive synchronous electric spindle featuring a magnetic ring incremental encoder (sine and cosine) with a positioning accuracy of 20 arc seconds and C-axis indexing accuracy of 40 arc seconds, this spindle system effectively eliminates vibration and maintains nose deflection accuracy within 0.002MM. The rear-mounted rotor allows for swift installation and maintenance, while the spindle motor's advanced cooling system ensures consistent operating temperature by counteracting thermal displacement. After rigorous dynamic balance testing, the spindle's design retains high accuracy, rigidity, and efficiency, adeptly handling both finishing and heavy-duty rough machining. Ideal for mass production of intricate and smooth components.
2. The high-rigidity integrated servo power turret design enhances rapid and precise tool changing capabilities. Coupled with the high-speed power axis for power milling, it delivers exceptional combined turning and milling processing performance. The high-rigidity BMT installation interface ensures sturdy tool holder attachment, driven by a servo spindle motor.
3. Featuring roller linear guides and precision-ground ball screws, the machine guarantees optimal accuracy and durability. Each axis incorporates a direct transfer structure and double-anchor pre-relay method to minimize thermal displacement, thus significantly improving processing precision. The high-rigidity, large-sized, heavy-duty linear slide rails maintain precise accuracy under impact, offering smooth, low-noise displacement and extended service life.
4. Users benefit from a comprehensive hydraulic and lubrication system using premium hydraulic pumps and valves, which significantly reduce failure rates. These systems are meticulously designed for simplicity and reliability, ensuring seamless operation.
5. Featuring a Taiwan rotary chuck cylinder and an optional automatic chip removal device, this machine drastically reduces operator workload and enhances production safety and efficiency. The programmable and controllable components can be customized to meet specific user requirements, including special fixtures.
