in machining a few batches of simple parts out of vitrex PEEK polymer in the natural color one batch came out with little dark brown speckles on them.
has anyone else ever seen this problem? is it a condition with a known cause? is it a problem in the PEEK?
if anyone knows or has seen this please let me know.
thanks a lot.
