CNC machines run at high spindle speeds with rapid axis motion. The guard door interlock must lock during spindle rotation and release only when motion has stopped - requiring solenoid guard-locking safety switches.

Where CNC Safety Switches Are Used

  • Main spindle enclosure door (locked while chuck spins).
  • Chip conveyor / tool magazine access door.
  • Rear coolant tank access.
  • Automatic tool changer access panel.
