Often times i will experience a poor lathe finish when turning 01 steel... usually when turning smaller diameters. At my work we really only do lathe work for roughing out pins which are then ground, so really the finish/appearance/accuracy of the lateh work means nothing so long as you can finish grind it.
But i want to know how to do better on the lathe as i hate the finish i often get. As the pins are only usually 1.5 - 2.5 inches long, a tailstock isn't used.
The finish i often recieve looks like it has like a bunch of shiny spots on it and dull spots also... this is using carbide insert tooling turning at 1000rpm... it cant be a dull tool, since even when i change to a new insert i still often get a poor finish.
If any of you could tell me things that cause this and solutions i would be much obliged ... I will post more information if needed.
