How to make ULTEM better by CNC machining?

ULTEM refers to PEI (abbreviation for polyetherimide), which is an amber transparent solid. It has inherent flame retardancy and low smoke without adding any additives. The oxygen index is 47%, and the combustion rating is UL94-V-0. , The density is 1.28~1.42g/cm3.
Due to its excellent comprehensive balance performance, PEI has been effectively used in industries such as electronics, electrical machinery and aviation, and used as a metal substitute for traditional products and cultural and daily necessities. Using PEI instead of metal to make fiber optic connectors can optimize the component structure, simplify its manufacturing and assembly steps, and maintain more precise dimensions.
