I have a bunch of delrin jobs coming up. Just wondering what you guys use for speeds, feeds, and coolant? I plan to use endmills designed for aluminum, and standard drills and taps.
I'm programming the first job now. I'm using 1/2" and 1/4" SGS S-carb endmills. I've heard use high rpms with coolant and I've heard use low rpms without coolant. I've also heard large step over with a high feed.
If I could cut dry it would make cleanup a whole lot easier. Not sure how well drilling will work without coolant though. I've got a couple 6-32 tapped holes and a 1/16 hole. I'm envisioning lots of chips wrapping on the drills and tap.
Any advice appreciated!
