CK7516 Series CNC Lathes

  • CK7516,CK7516A,CK7516C

  • BOCHI

Availability:


    The CK7516 series is a CNC lathe designed for high-precision machining of small to medium-sized complex rotating parts. 

     It is equipped with a high-end CNC system, motors, and a multi-position servo turret. Featuring high spindle torque, fast rotational speed, and quick tool change, it is suitable for high-efficiency machining environments. With extremely high positioning accuracy, it can meet the manufacturing requirements of various high-precision products. 

    The adoption of modular design makes it more adaptable to automated configurations. Furthermore, through optimized design using finite element analysis and dynamic-static simulation, it can effectively resist vibration interference during high-intensity machining processes, maintaining high rigidity while ensuring highly stable machining accuracy. 

    The key accuracy of the entire machine is improved by 30% to 50% based on national standards.
