I just purchased a brand new Grizzly G0791 lathe/mill combo which is the first of either I’ve ever owned,operated or even been around and I’m quite surprised with the hate these machines get. I’ve been using a 2” and 2-1/2” face mill with all but 1 insert removed and getting excellent results but that’s a whole other topic. My issue is on the lathe side of things. I’ve got about 3 solid weeks of using it and just last I was able to finally get an almost mirror finish on some, what I’m pretty sure is a36 with a roughly 2” od, but can’t break a chip. I get these long stringers which are a pain in the but.
Will too low or too high a feed rate cause this? I’m using a 5/8 holder with a wnmg insert. 1000rpm ,525 give or take a couple sfm, dry, feed rate not exactly sure bc I was changing gears so much I just quit looking the chart and would just move the pin to the next hole till I got a good finish. Thanks
