4th Axis CNC dividing head/Rotation Axis kit Nema23 Gapless harmonic gearbox + Tailstock CNC  MILLING

HIGH PRECISION - FOR CNC MILLING MACHINE

Package Includes:

1 x 4th Axis 3 Jaw 100mm chuck

1 x Tailstock

Chuck :

100MM three jaw self-centering chuck

Center Height 65mm

Total height, 115mm

Angle, 0.036 degree/step

Reduction ratio: 50:1 (synchronous deceleration mode)

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

Fourth axis pulse equivalent settings:

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
