Milling carbon filled UHMW

Milling carbon filled UHMW

(OP)
I'm looking for any suggestions on milling carbon filled UHMW.  The problem we are having is that the chips aren't clearing, and just "fuzzing" up.  Using a 2 flute 0.218" dia ballnose cutting 0.046" dp with the tip, our max spindle speed is 5k and thats where we are running.  I think the main problem with the process is that we are using a rotary table (max 15rpm rotation) to change part orientation during cutting, and the geometry dictates a feed of 3 ipm due to the ro-tab.

I am considering a vortex tube cold air gun, but don't think it will have sufficient velocity to blow the chips out before they re-weld theirselves back to the stock mat'l.

Vortec cooling would certainly be something to try and it uses a relatively inexpensive device, the cost being the compressed air to power it.  We have used up to three devices at a time on a  milling machine.  

One other method we used for machine cooling where we needed a large volume of cold air was a modified industrial spot cooler.  I don’t see why one of the portable room air conditioners couldn’t be modified to cool the machining operation.

We tried a cool tube about an hour ago, and it worked just fine.

Thanks
