    Finished parts

    【Main use】

    This machine is used to grind various cylindrical worms (ZA, ZN, ZI, ZK, ZC1), and also can be used to grind trapezoidal screws。

    【NC system configuration】

    1、SIEMENS 828D system, controlling 5 NC axes, 3 of which is in a gang

    2、Axis Z: table longitudinal traverse

    (With grating scale)               full close-looped

    Axis X: wheelhead cross feed

    (With grating scale)               full close-looped

    Axis C: rotation of work spindle

    (With angular encoder)             full close-looped

    Axis V: vertical feed of dresser slider

    Axis W: horizontal feed of dresser slider

    【Working accuracy】

    Cylindrical worms:

    when thread start=1-2, the accuracy is up to grade 5;

    when thread start≥3, the accuracy is up to grade 6。

    Trapezoidal screws: The accuracy is up to grade 6

    【Technical characteristics】

    1、Wheel dressing is done by two diamond discs moving simultaneously

    2、The wheel spindle is driven by an AC servo motor, and the speed can be regulated steplessly

    3、The adjustment of helix angle is done and locked manually
