I have some parts that were ran on a box roller box tool on my CNC lathe.
Taken from 5/8D 303 and turned to .250 +/-.0005 x (?) 6" long. (1 pass)
Parts come out looking and measuring fine, but the rod tends to have a bow to it. Some strait, some real bad, others in between. I have ran these and others like them several times in the past - and this is always an issue.
I don't know if it is something that I am dooing wrong, or if it possibly is the bar it'self? I am wondering if this is stress left from the straitening process of the original bar?
Also - other than tossing between two V blocks and tapping it - anyone know of a better method to tweak them? (There's only 75 pcs.)
Swiss
I have not ran these in my Swiss yet. (Actually - I'm concerned with push-back in the collet with this much thrust.) I have ran some REALLY long rods in there with this much L/D and they look strait as an arrow, but those weren't peeled down nearly as drastically as this one, and also made from med carb steel as well. Has anyone seen similar effect in the Swiss machine on this kind of L/D/peel depth?
