  • CNC High Precision Thread Grinding Machine

    • A CNC high precision thread grinding machine is a dedicated machining system designed for grinding high-accuracy threads under CNC control. By executing pre-programmed machining paths, the grinding machine precisely controls the relative motion and speed between the grinding wheel and the workpiece to form external and internal threads through profile grinding. Micron-level machining accuracy can be achieved, making the grinder ideal for processing high-precision threaded components such as ball screws, precision worm shafts, and trapezoidal screws. The grinding machine is widely used in precision transmission equipment for machine tools and robotics, as well as in aerospace and high-end automotive manufacturing for transmission component grinding.

    Key Advantages
    • Exceptional Machining Accuracy and Stability: Advanced CNC control, high-rigidity mechanical structures, and real-time error compensation technologies enable lead error ≤3µm and profile accuracy ≤1µm, ensuring long-term machining consistency.
    • Strong Capability for Complex Thread Profiles: Multi-axis synchronous control allows external threads, internal threads, multi-start threads, and variable-lead threads to be ground in a single setup.
    • Excellent Batch Production Stability: Equipped with automatic wheel dressing, automatic balancing, and in-process measurement functions, the system dynamically compensates for errors caused by thermal deformation and mechanical wear. Batch production yield can exceed 99.8%.
    • Large Machining Capacity: Maximum workpiece length reaches 8000mm, with a maximum diameter of 500mm, meeting the production requirements of large-sized components.
