This may be a no-brainer to most of you, but I'm a bit baffled by this one. In my business, I have to cut down brass bushings (on a lathe) to accurate lengths and would like to have some suggestions on how to do this consistently without having to measure and mark each bushing and try to hit the mark accurately each time with the parting tool. Maybe some kind of a stop system to get the bushing and cutter into position so all I have to do is insert the bushing into a chuck stop, and bring the parting tool to its stop, and part it. For example, I have a 2" long brass bushing and I have to make two bushings at .750" each. Currently I use a dial caliper set to .750" and scribe two lines (one from each end) to make my marks for parting. I chuck up the bushing so that both lines are showing with a little extra hanging out of the chuck, cut the bushing that is furthest out first, then cut the remaining small piece from the bushing that is still in the chuck. Then I have to slowly trim each bushing to the correct size, bit by bit until the proper dimension is achieved. I have to stop the lathe many times to make sure I don't cut too much off. Then I have to radius the end of the bushing to eliminate burrs.
Is there some kind of stop made for a chuck that would set the bushing to a certain depth every time so that I could lock my cross feed to a certain position and just part the bushing accurately every time? I have a few different diameters of bushings that I have to do this to.
There must be an easier way...:thinking:
