Bonded Collet Spindle Maintenance


  • Collet failure will occur without this maintenance.
  • During collet maintenance you may experience black deposits coming from the collet. This is lubricating grease and should not be flushed away.
  • Mandatory maintenance should occur every 100 hours.

Maintenance Steps

  1. Spray “CRC” lubricant into collet bore via tube for 1 second.
  2. Replace tool and run spindle at 100,000 rpm for two minutes.  
  3. Stop spindle and clean collet bore with a brush and solvent.
  4. If contamination is evident repeat the whole process.
