    Product Details

    Description

    Advanced Engineering for Extra-Large Scale Machining

    The CK61125 CNC Lathe Machine is the definitive solution for manufacturing environments that require maximum swing capacity and extreme structural rigidity. With a 1250mm swing diameter, this heavy-duty flat-bed lathe is specifically engineered to handle oversized components such as large flanges, heavy-duty shafts, and maritime equipment parts. Its massive construction ensures superior stability, significantly reducing thermal deformation and vibration during aggressive material removal.

    Technical Excellence & Operational Flexibility

    Designed for the challenges of 2026 industrial standards, the CK61125 combines raw power with sophisticated control:

     

    Versatile Tooling: Supports 4, 6, or 8-position vertical tool posts to accommodate complex machining sequences with a large 25*25mm tool bar size.

     

    Heavy Support: Equipped with an MT 6# tailstock with 250mm travel, providing rigid and secure support for long, heavy workpieces between centers.

     

    Durable Performance: The machine provides the necessary mass for high-precision finishing, achieving a surface roughness of Ra 1.6 μm and workpiece accuracy of IT6-IT7.

     

    Global Compatibility: Fully compatible with professional CNC systems, allowing for seamless integration into automated production lines and smart workshops.
