Controls for PEEK Components
Cutting Heat and Chips
Use sharp tools, suitable engagement, and reliable chip clearance to reduce rubbing, heat buildup, and poor edges.
Support and Stock Stress
Plan stable support, controlled clamping, and balanced removal. Review stock conditioning or intermediate stress relief where appropriate.
Reinforcement and Tool Wear
Glass- and carbon-filled grades require tools and edge-finishing methods matched to abrasive fibers and directional behavior.
Finished-Part Acceptance
Define critical fits, datums, temperature, support, surface condition, and material records before final inspection.
*Planning references confirmed against the drawing. Maximum size, thin walls, small radii, tolerance, and roughness are assessed separately and should not be assumed achievable together.
Select the PEEK Grade for the Part
Match formulation to load, temperature, wear, electrical behavior, chemical exposure, and required material documentation.

PEEK Machining Questions
What makes PEEK demanding to machine?
Cutting heat, stock stress, burrs, tool wear, and reinforcement can affect size and surface quality. Use a grade-specific route with suitable tooling, supported workholding, controlled material removal, and defined inspection conditions.
Which PEEK grade is easier to machine?
Unfilled grades generally avoid the abrasive fibers present in reinforced grades. Filled materials may offer greater stiffness or lower expansion, but require tooling matched to the filler, stock direction, and required edge condition.
How are close tolerances controlled?
Review suitable stock, balanced removal, heat, support, and stress relief where appropriate. Stabilize the part before final sizing or measurement and agree the temperature, support, and acceptance method for critical features.
Which tools suit reinforced PEEK?
Suitable carbide tools are used for many operations, while PCD can improve tool life in abrasive reinforced grades. Geometry, chip space, engagement, rigidity, and the specific filler influence the choice.
Can PEEK parts be polished, coated, or marked?
Yes, with a compatible process for the grade and function. Define roughness, marking contrast, masking, and final fits. Coating or printing requires an agreed surface preparation and adhesion acceptance.
