Ranque-Hilsch Vortex Cooling Tube

I purchased one, Chilly Bits brand. Have it set up on the Bridgeport. Not overly impressed. It helps some, mostly with chip clearance, but not as good as regular cutting oil, and as noted above it eats a lot of air, and if you don't have a commercial sized compressor, don't waste your time. Mike
 
The thing is I do more aluminum which needs lub so I use the Noga misters on both the mill and lathe. It would work on steels but I just don't do a lot of steels. Some cold or hot rolled and the mist works got on them. Don’t need any thing on cast, just air to clear chips and the misters cand also provide the coolair for that. Unless your cutting exotic materials with extreme tolorances, then maybe. This is more suited to NASA/Livamore Labs stuff. Hobby stuff, trick of the week. Not to mention the ware and tare on the compressor. and the 400.00 plus for one that does any real good.
