    Description

    The Heavy-Industry Standard for Large-Scale Turning

    The CK61140 CNC Lathe Machine represents the pinnacle of heavy-duty horizontal turning technology. Engineered specifically for the world’s most demanding sectors—including energy, shipbuilding, and large-scale mechanical engineering—this machine offers a monumental 1400mm swing capacity. Its reinforced flat-bed architecture is built to withstand the immense forces generated during the machining of oversized flanges, heavy shafts, and large-diameter pipe fittings, providing a vibration-free environment for consistent accuracy.

    Unmatched Stability & Industrial Precision

    Designed for the rigors of 2026’s manufacturing landscape, the CK61140 integrates immense physical strength with refined CNC control:

     

    Advanced Tooling System: Standard equipped with a Vertical 4-Station Electric Tool Holder (with 6/8 station options) and a large 40×40mm tool bar size, allowing for heavy material removal in fewer passes.

     

    High-Load Spindle Architecture: The spindle features a Metric 140 1:20 taper and is supported by precision bearings to maintain a roundness of 0.01mm even under significant radial and axial loads.

     

    Dynamic Response: Despite its size, the machine offers rapid traverse speeds of 4000/6000 mm/min (X/Z axes), driven by high-torque servo motors for responsive and efficient movement.

     

    Long-Term Reliability: The induction-hardened bedways and centralized automatic lubrication system protect the machine from wear, ensuring that your investment maintains its precision over decades of heavy use.
