Spindle Speed

The rotational speed of the machine spindle, measured in RPM (revolutions per minute). It determines how fast the cutting tool or workpiece rotates during machining.

Spindle Speed

Definition

The rotational speed of the machine spindle, measured in RPM (revolutions per minute). It determines how fast the cutting tool or workpiece rotates during machining. Use this entry as a shop-floor reference, not as a detached textbook definition.

Formula / Rule

  • n = (1000 × vc) / (π × D)

Typical Range & Scenarios

  • Review speed with power curve and balance limits.
  • Review the result against setup, rigidity, and inspection method.

Common Errors / Troubleshooting

  • If wear rises fast, verify heat and coolant first.
  • Recheck state, datum, and measurement chain before editing offsets or code.
