Bugger..... 3 perfect flutes and 1 chipped one... And I know exactly when it happened. Just before that last pass I y traveled a tincy bit too far and bumped the vise jaw. I hear it clunk... Jebas!
Could the X gib need snugging up?Got the DTI set up to see if I can see any wiggle while the table travels... Bigger issue, x table is .0035" higher on one side of travel than the other. That's not even a tram issue, that's just the table being out to lunch...
I dunno anymore. Lol
I guess I sorta got what I paid for when I bought a mini mill.
I use roughers all the time, and I think my 8520 only has 3/4 hp. I value them as they take a good amount off, and I find they don't give me a problem usually. I did destroy one a few weeks ago, on what must have been a chunk of forged metal. (DAMN)Might just get a stick of stressproof or 12L14 and make life easier. Personally , and its just my opinion, but unless I had at least 2 or 3 hp I would not fool with roughers, they are made to work, requiring a pretty good feed, and the rough surface teeth and a flexible mill set up do not lead to a happy situation. A nice fresh 4 flute endmill will likely suit you better.

Yup, it only takes one.
So I have wondered this but never tried it - If one were to grind away the damaged tip so that only the other three touched the material would the cut improve?
