Cutting Delrin

[CD13]

I have the 1/2 in stuff and wanting to cut some skids.Will a radial arm saw work or do I need a slow band saw? Thanks for the help. "thumbsup"

You'd probably be better off with a slow band saw, it will minimalise the amount the delrin burs and shaves up at the edges. I use a band saw to work in perspex stuff (similar but harder/more brittle) and it does a good job.

I've cut it on a table saw before. It works like any hard wood. Just make sure you do complete, quick cuts. If the blade sits running against it, it will melt and stick to the blade. Try a little WD-40 as a cutting oil.

Yeah you definately don't wanna let it sit, it will melt and stick to everything.... I just used a jig saw but the cuts were not the straitest and it did remove a lot of material

I use a Kitamura mycenter 3xhi with a Fanuc controller.Cuts Delrin perfect....or aluminum or steel or titanium.....But I geuss If I didn't have a CNC mill a table saw would make do.With a little practice you should be able to make some nice cuts. I would use a regular High speed blade and not a carbide tipped one as the regular ones are sharper and will make cleaner cuts.

That's my prefered method. I also use a horizontal band saw to cut round rod. One thing is for certian though.....it freakin' smells like you just cut a skunk in half.:lol:haha....

I work with lots of bone. NOTHING in the world smells worse than Sheep or Ram Horn. It smells like burning bones that someone tried to put out by peeing on them :lol: To me, Delrin just smells like plastic, not TOO bad.

it depends on the blade you have for the radial arm saw. a fine tooth blade will work the best. You should try a scrap pc first. I have cut 4x8 sheets of delrin w a circular saw to get the sheet into workable sizes.

Use a jewelers saw. I just cut this with no problem and you can make pretty shapes with it if you like. go with power only if you need to do production or you have nice jigs. here is what I use check the rest of the gallery for a skid plate I just made with delrin.

Has anyone ever used a mini rotozip type cutting bit on a mini rotary tool. I would think that would get the job done for cutting intricate shapes. I hope to cut some delrin chassis plates like that pretty soon.

I cut delrin all the time. I have used about every method imaginable to cut delrin....and they all work about the same...GREAT. Delrin is very easy stuff to work with8)
I've used radial arm saw, table band saw, metal cutting band saw, skill saw, chop saw, table saw, router, lathe, mill, and a whole lot more:mrgreen:
I'd say the easiest, cleanest, quickest, cheapest method to cut delrin sheet (for skids,ect) is the radial arm saw or table saw. Makes a nice strait cut.
Also hand files work great on delrin for the fine details and finishing work"thumbsup"

how about a dremel will it work?

just tried it,and it works very nice.I have a larger drill press.
set the pullies for max rpm [3500] and used a zip bit for wood.
I tried it on wood first [just to see] and for balsa its ok. but for anything dense,not so much.

the delrin I cut is 4mm thick. it does have a slight tendency to pull to the right. but as long as I took my time and didnt take to big a bite at once it was all good. definatly a very cheap option if you already have a drill press. the bits are $6 for a 4 pack.

I've cut up to 3/4" on my table saw and miter saw with no problems. I usually cut 5/8" all the time.

I just use my dremel with a metal cutting wheel (the reinforced one by Dremel) and cut on a slower speed. That way It doesn't melt. I also made some test cuts and know how it cuts now so I make sure to mark it right so my cuts don't turn out too short. My 2 cents.

I didnt want to drop coin for a scroll saw,need to cut tight radious
the zip bit in the drill press worked great.basically used the base as a table[cranked it up past the bottom of the bit]
