  • Description


    1 pc — 4th Axis 80mm 4 Jaw Chuck Positive jaw and counter jaw )

    1 pc — Tailstock




    • 80MM four jaw self-centering chuck

    • Center Height 65mm

    • Total height, 115MM

    • Angle, 0.3 degree/step

    • Reduction ratio:6:1 (synchronous deceleration mode)

    • Magnetic stepping motor: Two-phase 57 step motor Four-wire



    The Mach3 system settings:  the pulses for 1  required:

    ( the motor 1 Circle of pulse number × the drive of subdivision number × reduction ratio) ÷ 360 degrees

     For example, the two-phase 57 motor, the ubdivision number 16, the reduction ratio 50:1

                          (200 × 16 × 50) ÷ 360 = 444.44444444)


    Ncstudio system settings: the angle of a pulse walking:

      360 ÷ (the motor 1 Circle of pulse numberr × × the drive of subdivision number × reduction ratio)

     For example: the two-phase 57 motor, the breakdown of the number 16, reduction ratio 50:1

                          360 ÷ (200 × 16 × 50) = 0.00225


    X or Y axis instead of the algorithm is:

     Circumference ÷ (the motor 1 Circle of pulse numberr × × the drive of subdivision number × reduction ratio)

     Engraving different sizes of round bars, equivalent needs to be set.
