Best machined Surface Finish for PEEK
Best machined Surface Finish for PEEK
(OP)
Hello,
I'm wondering what the best possible machined surface finish for PEEK is. The part is a small water resevoir, which will have the cavity milled out. At present the prototype is rough machined, with mill lines still visible, which disturbes the flow of water over the area. Basicall, how smooth can I go with PEEK.
Any suggestions will be much appricated.

You need to know what you want, what you need, and what you have, how big the differences are and whether you can improve and at what cost to what extent.
You need to discuss this with your machinist, and possibly several others, then decide what you need re cost benefit.

Milling this stuff should not be much different. Just be sure the machining house is using correct cutting parameters.
Hand finishing could bring that down to at least 16 Ra if you are willing to pay for it.

Optionally, you may coat or make a liner that has a better wetability than PEEK.
