Polyetheretherketone (PEEK) is a high-performance thermoplastic used in the production of parts subjected to harsh environments such as high temperatures and chemicals. Being lightweight, it provides an excellent alternative to the majority of soft metals. However, its machining process is complicated, and it requires a level of expertise and experience to work successfully.
In this article, we’ll talk about PEEK CNC machining, how it works, its pros and cons, tips for the CNC machining PEEK process, surface finishes and applications for PEEK parts. Lets’s move forward to learn more.

FAQS of PEEK CNC Machining
The internal stress in the material is either not fully removed or there is no annealing process performed to eliminate it.
The CNC cutting depth has been set too deep.
There is no coolant being used to dissipate the heat generated from cutting.
The cutting process is irregular and uneven, resulting in more cuts on one side than the other.
Vibration is occurring in weak clamps that are unable to hold the workpiece securely.
