I am trying to teach myself how to use a lathe after learning some basics from an old timer. Please see my pictures. I expected a much better finish both turning and facing. So I have a couple questions:
Is the angle of the tool to the work piece correct?
I am at 140 rpm which would be about right for a HSS tool and this diameter. But should I use a different speed for this insert?
I am taking off 0.010 each pass.
Maybe I am missing some other factor? Chuck rigidity?
Thanks for any help.
Get a material like 12L14 so you can eliminate issues trying to machine some shitty material that might not give you a good finish no matter how hard you try
