  • SWM1505/1510/1520
    CNC External Thread Grinding Machine
    Feature and Parameter
    Configuration and Workpiece

    * The machine adopt T type mineral casting frame, X/Z axis use  Heidenhain scales to feedback location. Rotary table can adjust helical angle of grinding.
    * The machine spindle drive by motor spindle. The motor spindle (10000RPM) of diamond grinding wheel dressing is installed on spindle box, it dress grinding wheel and multiple wheel shape.
    * The machine clamping way have two center holding and heart-shaped clamping toggle, also have four-jaw of spindle and tailstock to hold on  ex-circle.
    * The motor spindle of the machine workpiece and grinding wheel adopt constant temperature coolant system, it ensure the spindle work more stable and high precision.
    * Automatic completion processing of lead screw: cutting,
    grinding, tool retracting, grinding wheel  dressing , grinding wheel spindle swing, etc. If the machine process to add multiple head nut , it can grinding for both way side. 
    * Grinding fluid adopt cutting fluid filtration device and magnetic separator to keep temperature by oil coolant device , it is better to process precision and machine spare part well.
