💡 What happens when you skip balancing the spindle shaft on a CNC frame? Getting the rotor perfectly aligned is pretty handy since it stops vibration before it warps your workpiece or cracks a collet sleeve. Aligning the spinning guts correctly keeps your cuts dead straight and your tools running cooler. - Skipping balance checks introduces shake that blurs fine details during tight radius sweeps - Unbalanced spin cycles raise casing heat fast and fry the internal windings early - Checking static balance keeps torque locked flat and stops your stepper drivers from choking mid pass
