Nylon 66 machines great
The worst problem is the stringy cuttings getting tangled up in the chuck
Nice sharp tools is the way to go

Let me reiterate John's advice -- SHARP cutters. If you can rig up a vacuum cleaner to pull chips as you machine, it will save you a lot of pain. Also, a good heat gun can save your bacon when it comes to deburring. Does that help?

When machining delrin I use "pam" spray (cooking oil in a can) to keep things clean and smooth. Given I'm in Oz - the spray I use is a cheap knockoff of "pure and simple" but our US cousins know it as pam.
it seems to improve surface finish, but does littel for the stringy swarf wrapped around everything.

what i do when roughing is a fast speed and heavy feed , and interrupt the cut by stopping the feed or if feeding by hand stop and back off to break the chip but you will still get stringers. need to be careful not to get them tangled on you as they will cut. on the finish use a fast speed and a light cut but the feed can still be fast. after roughing and drilling let it cool as it gets hot fast. again watch the stringers as they tangle fast, god luck. jonesie

Parts off easily with a sharp tool.

I sometimes keep the swarf from machining delrin and use it to scrub pots. Don't try this with metal swarf though!
