OK, I forgot some things.
I don't have a mister.
I've cut 16 of these parts (in a row) with one endmill (uncoated carbide no name). I was running it at 40 ipm with a .125" DOC.
Then all of the sudden, that mill broke. And the other one I had just like it lasted like 30 sec, and then another 30 deg helix EM lasted about 3 sec. So I ordered some coated Niagras with half the LOC so they would be stiffer. This one cut like a champ, and then just exploded. Not a sound, until it broke. Perfect surface finish, then boom.
I don't understand what is happening here.
I tried doing the same thing that worked for all those parts in a row, except now it only ends with exploded endmills.
What has changed?
Why won't that work now?
This is insane, I am contemlating giving up machine work, and buying a pottery wheel.
Somebody stop me!!!!
