Heavy Duty CNC Lathe Machine CNC Turning and Milling Center with Y Axis

Product Description

Product Description
Our state-of-the-art two-axis lathe revolutionizes machining efficiency by enabling simultaneous processing of both ends of the workpiece in a single clamping. This innovation not only simplifies manual operations but also significantly enhances output and streamlines processes. The secondary spindle facilitates comprehensive turning and ensures seamless workpiece transfer during machining, thereby drastically reducing cycle times. Featuring an optimized 30-degree inclined structure, this machine boasts unparalleled precision, exceptional rigidity, and superior cutting stability. Constructed from a robust single-piece high-strength HT300 cast iron lathe bed, the machine employs finite element analysis to guarantee outstanding mechanical rigidity and stability, maintaining long-term accuracy, enhancing processing stability, and prolonging tool life. Stress relief treatment further augments accuracy stability. The high-strength roller linear rail design, coupled with a screw pre-tension transmission system, elevates rigidity performance. The machine's minimalist and elegant appearance aligns with contemporary design trends.
Distinguished Main Features of this Machine Tool:
1. Incorporates a direct-drive synchronous electric spindle device: Featuring a magnetic ring incremental encoder (sine and cosine) with a positioning accuracy of 20 arc seconds and a C-axis indexing accuracy of 40 arc seconds, this setup effectively eliminates spindle vibration, ensuring nose deflection accuracy within 0.002MM. The spindle motor's cooling system mitigates the effects of thermal displacement, maintaining a consistent operating temperature. Rigorous dynamic balance testing of the spindle system guarantees excellent accuracy retention, high rigidity, and efficiency. This makes the machine adept at both finishing and rough machining, as well as heavy cutting, especially suited for mass production of complex, high-smoothness products.
2. High-rigidity integrated design servo power turret. Enhances rapid and precise tool-changing performance. When paired with high-speed power axis milling, it delivers outstanding combined turning and milling capabilities. The tool holder features a robust BMT installation interface, and the power transmission shaft is driven by a servo spindle motor, ensuring exceptional performance.
3. Equipped with roller linear guides and precision-ground ball screws, this machine ensures optimal accuracy and durability. Each axis features a direct transfer structure and a double-anchor pre-relay method, minimizing thermal displacement and significantly improving processing precision. The high-rigidity, large-sized, heavy-duty linear slide rails maintain accuracy under impact, offering smooth, low-noise displacement and prolonged service life.
4. Comprehensive hydraulic and lubrication systems. Utilizing premium hydraulic pumps, valves, and components, the design significantly reduces failure rates. These systems are engineered for simplicity and reliability, ensuring seamless operation.
5. Featuring a Taiwan rotary chuck cylinder and an optional automatic chip removal device, this machine dramatically decreases operator labor intensity while ensuring safe and efficient production. All functional components can be programmed and controlled, with customizable features available to meet specific user requirements. Special fixtures can also be designed and installed.
