1、4 Jaw K12-100mm

Engraving machine fourth axis (A axis, Rotational Axis, CNC dividing head) gapless harmonic reducer gearbox

Chuck type: K12 100mm 4 jaw centering chuck

Center height: 65mm

Total height: 115mm

Angle: 0.3°/ step

Gear box output shaft diameter: 25mm

Reducing ratio: 6:1(belt deceleration mode)

Stepper motor: Nema23 57mm 3A 2-phase 4 wire

The fourth axis parameter settings:

Mach3 system settings: the pulses required for 1°

(Motor 1 lap pulses x Driver fine fraction x Reduction ratio) ÷ 360°

For example: 57mm 2- phase stepper motor, fine fraction of 16, reduction ratio 100:1

(200 x 16 x 100) / 360=888.88888888)

Weihong system settings: 1 pulse along the angle

360°/(Motor 1 lap pulses x Driver fine fraction x Reduction ratio)

For example: 57mm 2- phase stepper motor, fine fraction of 16, reduction ratio 100:1

360 / (200 x 16 x 100) =0.001125
