1/4" Shank solid carbide bar with 1-3/4" stick out of the sleeve.
WPGT insert .008" radius.
416 stainless.
Starting with a 3/8" drilled hole.
Final diameter .42".
Final depth 1.6"
Lots of coolant.
I'm new to CNC turning and having a hell of a time getting rid of chatter. Also not getting a chip to break. I'm getting a continuous spiral that wraps around the tool.
Does anyone have a recommended starting point for speed, feed and DOC? Also, if I'm using the wrong insert, feel free to recommend the ideal bar/insert that would be ideal for this.
