I have a batch of 6061 parts to make that I have always done on my mill despite being obvious lathe parts. I finally managed to get my Emco 220P lathes running and would like to turn them loose on this job. Problem is these lathes have a 1" bore, and these parts are made from 2" bar...
There are two parts in this assembly, one is about 1/8" thick and the other is 3/16", 1.95" finished OD with a 1" hole through the middle, and I need 100 assemblies total. At that size the amount of time and material lost from cutting a bar into 200 thin wafers would be ridiculous, so I'd like to cut them into slugs and get a few parts out of each.
In my mill I cut them into 4" pieces and using a slitting saw to part off I was able to step down and get 5 or 7 assemblies out of each before I reached the vise.
What would be a reasonable length to have engaged in the chuck and how much could I safely leave sticking out? I have some 3" step collets and they're about 1-1/8" thick. Or should I get the broom ready and spend a day cleaning up around the saw?
