Machining/Cutting Nylon?
Is there a special tool or technique I can use to machine nylon stock? I've tried cutting with my table saw, band saw and tried to machine some on my mini-mill with dangerous results. I guess if I cooled it with coolant it might work better but don't have that open on table saw or band saw. Just starts melting as you cut.

Yea, I can slow it down on my mill but I need to be able to cut my stock down to size with my table saw and band saw.
Try using a sliding cutoff sled with the table saw.

barkster,
I found that nylon cuts very nicely if you cut it very fast. I would try pushing it thru the table saw or band saw as fast as you safely can. Should work with either. For machining, again, go fast. Large chip loads will remove the heat with the chip and spare the part any (at least most) melting.

We cut it all the time, just run it fast you shouldn't need any coolant. They do make special blades to cut it, and work well.

As they say use high feedrate, and also make sure that you use sharp tools, prefered is a brand new tool one in HSS since solid carbide isnt as sharp as a HSS tool.You can also try to use some sort of alcohol as coolant,but be carefull so it doesnt ignite.
Yup - I concur!
HOG IT! - get the chip load up - either use a very coarse blade and/of bog the motor down with very aggressive feeds.

Consistency is a good thing....unless you're consistently an idiot.
HOLD IT!!! BE CAREFUL with your alcohol selection against nylon!!!!!!!!
Ethyl is fine, DO NOT USE Isopropyl or Butyl alcohols with most plastics!
The best compatability tables I have seen are here:

i checked with grizzly tools when i did my delrin they had bits for plastic so i got one it only has one flute on it works great
I use my 10" table saw to cut 5/8" thick nylon 6/6. I had a tough time with it melting. I tried a lot of things (lubricants, freezing the nylon, etc. ). Then I found out from my plastic supplier that they use a special nylon cutting blade. I had one made at a local saw blade manufacturer (Universal Saw in Santa Fe Springs, CA). The carbide tipped blade has 20 teeth. Fewer teeth keep the blade much cooler and it cuts a LOT cleaner as a result.

Hi there. I read your section about cutting 5/8 nylon. Interesting. I thought a regular sawblade would cut without melting. Anyways, where do you get your 5/8 nylon? I found one place ( Natural Nylon Square Bar 5/8" | U.S. Plastic Corp. ) but the nylon is sold by the foot. I need atleast 2 foot sections to make a window track for my dads backyard storage shed.Originally Posted by Lon Salgren
I'm not an expert machinist, but I noticed that while turning some hard black nylon plastic parts in a lathe, the plastic expanded quite a bit, and then shrunk juts as much afterwords.
When reading this, I wonder of cooling might help keep the part size more stable. Perhaps a water-based coolant with a rust preventative?

Contact your local plastic supplier. I have 3 or 4 available locally that all have names beginning with the letter "P". Some have a retail store in addition to the wholesale business and have rems available for cheap. If not, they can cut you a piece of nylon to your specifications. I have rems from my machining operation, but they are only 1' long. I buy the nylon cut to 1' x 2' sheets, then I cut the strips to 1' after the initial planing operation.Hi there.

I already called Lowes, Home Depot, Pittsburgs Paints and none have the strips that I need. And there are no retail or plastic companies around my county. I live WAY down south in California (Imperial Valley). To give you a better location of where Im at, remember the 7.2 Easter Earthquake? Well lets put it like this, the ground swayed around 1 foot and a half from side to side. I live just 15 minutes N. of Mexicali, Mexico, the epicenter. Anyways, I'm gonna have to do some searching. Searching is harder than I thought, even on the internet. Any suggestion Mr. Salgren?
By the way, where is your area?
Newbie81,
The link you provided states as follows.
"The standard length is 4ft, sold in 1ft intervals"
Order as many 2 foot pieces as you need.
