Match Grinding

CAPABILITIES
When marrying two parts, our Match Grinding capabilities ensures precise I.D./O.D. fits. We can meet diametral clearances as close as 1.5 microns. We offer several types of match grinding processes:
• Interchangeable – batch I.D.’s
  and O.D.s are held within
  controlled size ranges
• Select Fitting – parts are ground,
  individually gauged and selected
  for fit
• Grind-To-Match – two parts
  are specifically ground,
  measured and calibrated to
  match each other
