This started last night as I was drilling & reaming a 7/16 hole in a ¼ piece of 12L14 , the center drill chattered, then the body drill chattered, then the reamer. Let me say this, YES I understand proper speeds & feeds. I have seldom seen a center drill chatter.
Tonight, I wanted to finish the part I started last night, brand new ⅜ carbide finish mill, .030 deapth of cut, I get chatter, lots of it, kinda reminds me of when the slides on our big VMC go dry, so I pumped the oiler handle, and this happened, the mill dug into the work .005 to .007 .....WTF? I am so beyond baffled......up until this time I had not had any chatter.....I am stumped. By the by, the Z axis was locked, the quill was locked, the Y axis was locked. WTF? And yes one side appears to be deaper then the other side.
I hope @qualitymachinetools chimes in .....I'm wondering if I got another problem child
Anyways here is the picture ......anyone have any thoughts
