Frequently Asked Questions – PEEK CNC Machining

What is PEEK used for in CNC machining?

PEEK is commonly used for high-performance applications in aerospace, medical, and automotive industries due to its heat resistance and strength.

Can you machine glass-filled PEEK?

Yes, we specialize in glass-filled PEEK CNC machining, which offers enhanced strength and dimensional stability for demanding applications.

What’s the difference between a PEEK rod and a PEEK sheet?

PEEK rods are cylindrical, ideal for turning and rotational parts. PEEK sheets are flat and better for milling and larger surface-area components.

Is PEEK chemically resistant?

Absolutely. PEEK offers excellent chemical resistance, making it ideal for laboratory, industrial, and oil/gas applications.

How quickly can I receive a quote for PEEK CNC parts?

Send us your drawings and requirements, and we will normally get a quotation back to you 24-48 hours later.
