Frequently Asked Questions

Is PEEK easily machinable?

PEEK (Polyether Ether Ketone) is considered machinable compared to many engineering plastics, but it requires proper tooling, speeds, feeds, and chip evacuation strategies to achieve optimal results. Its semi-crystalline structure can cause tool wear if not managed correctly. At Criterion, our experienced machinists have refined proven processes for PEEK, routinely achieving tolerances as tight as ±.0002" and excellent surface finishes for medical device applications.
