💡 How does proper speed adjustment improve dual spindle lap operations?
Getting friction heat down early protects internal components.
- Tweak the rotation rate gradually so cooling fluids stay effective longer
- Match lower turns for fragile minerals and higher turns for dense alloys
- Watch for steady vibration feedback before committing to deep material removal
A reliable bench top lap runs smoother when technicians follow these speed guidelines.
