Kind of confused as to why this is happening. Using a 9/16” dia., HSS TiN coated 2-flute end mill, I had just cut a 9/16” section out of a steel, rear, motorcycle suspension link. Basically did this with three plunge cuts, then a pass back and forth to eliminate the resulting radii. Piece is just under ¾” in width and the cut wasn’t made all the way through. I left ~1/16” of material per the customer’s request. No problems that I could detect and it cut as I was expecting.
I clamped up the second link to make a similar cut, and it wouldn’t cut. The bit just started to chatter and dulled. Thinking I had damaged the bit on the first link, I replaced the bit with a ½” wide coated one and the same thing happened.
Even tho’ it’s an odd shaped piece, I am 99% sure I had everything clamped up tight. Mill is a Bridgeport Series 1.
I should add that my experience level is minimal. Strictly a hobbyist.
Aggravated, and confused.
