Side-milling test #2 into 304 Stainless. PM935 Mill.
Increased RPM from 486 to 625, increased feed rate to 6, then 9, then 12 inches/minute. DOC is .187", WOC is 3/8". The cutter took it in stride. But my PM935 was totally maxed out rigidity wise. Lots of shake, rattle and roll. Sorry for the compressor noise in the background. This certainly out performs my Iscar 1" APKT end mill by a large margin. So I'm happy with this face mill.
