Speaking of carbide in the home shop... I have been working with the settings of my VFD. The question is how fast should I set the upper limit? The faster the better for carbide, so I don't want to be overly conservative. Here's the factory info, advertised speeds.
Mine is a 14 1/2. I have a VFD and a Reese drive so I can hit outlandish speeds if I choose.
16" 980 rpm on 2 7/8" bearings
14 1/2" 875 rpm on 2 5/8" bearings
13" 940 rpm on 2 1/4: bearings
10" 1400 rpm on 2 1/4" bearings
Obviously we don't want max speed while swinging an off-center part in the 12" four jaw, but y'all think 1200 rpm for collet work would be an issue?
