Every time I use a slitting saw I always seem to have trouble. So I'm looking for any advice you have that I don't. Obviously I've missed some rules along the way.
My current job is 1018 2" wide bar with a 1.500 x .062 slot.
My first attempt was with a solid carbide 100 tooth 5" x 062 saw, straight tooth I would suppose it would be classified. I had actually ordered a carbide tipped saw, but due to a miscommunication, I ended up with solid carbide. It was not cheap. Anyway, I took it in 3 passes, climb, at I believe 400sfm at an embarrassing .0003 per tooth, I ended up there because my saw was running out like a motherfucker, and this machine is only 10hp. The arbor is new, and was made in America. We ran about 20 parts before failure. Which I suppose I expected, but couldn't get a better cut.
I came in today and reprogrammed for my only other saw, a HSS 6" x .062 x 42 tooth. Also straight tooth. I've switched to trying it in one pass, at 200sfm, and an even worse, .0001 per tooth. Any more an I stall the motor. The saw is also running out like crazy, which I can't seem to remedy, I see my spindle load bounce from 0-60 percent on each rev, and obviously it sounds like shit. Finally my slot is coming out angled, as in the saw is bending, approximately .030 higher near the arbor.
Aside from all the problems above, how does one prevent run-out with a saw?
Thanks,
Brian
