CNC Router Rotation 4th Axis 4 Jaw Chuck Harmonic Reducer 50:1 Rotary Table Rotary a axis 100mm chuck+65mm Tailstock for CNC Router Engraving Milling Machine


Advantages of Harmonic Drive 4th Axis vs. Belt-Driven:

  1. Zero Backlash – Maintains precision during bidirectional movements (critical for CNC milling/engraving).
  2. Higher Rigidity – Handles heavier loads without flexing (ideal for machining metals).
  3. Smoother Motion – Harmonic drives eliminate belt vibration/jerkiness for finer surface finishes.
  4. Compact Design – No bulky pulleys/belts, saving space on CNC setups.
  5. Higher Torque at Low Speeds – 100:1 gear ratio provides more cutting force for tough materials.
  6. Minimal Maintenance – No belt wear, tension adjustments, or replacements needed.
  7. Better Repeatability – Ideal for high-accuracy tasks like indexing or multi-sided machining.

The fourth axis parameter mach3 settings:

Mach3 system settings: the pulses required for 1°

(Number of pulses per revolution of motor x Driver Subdivision Number x Reduction ratio) ÷ 360°

  • For example: Nema23 2- phase stepper motor, Driver Subdivision is 16, reduction ratio 50:1
  • The pulses required for 1° is (200 x 16 x 50) / 360=444.4444444)

Weihong system settings: The angle traveled by one pulse

360°/(Number of pulses per revolution of motor x Driver Subdivision Number x Reduction ratio)

  • For example: Nema23 2- phase stepper motor, Driver Subdivision is 16, reduction ratio 50:1
  • The angle traveled by one pulse is 360 / (200 x 16 x 50) =0.00225
