Hello all.

I just got a G0768 lathe and had a question on the power feed feature. I am try g to machine 6061 1 1/4" round bar and keep getting a record finish. My power feed is set at its lowest which is .0037" I believe. I have tried both hss and carbide both with the same results as well as different rpms. Any advice would be greatly appreciated.

Thanks krank

Tool tip radius too small would be my first thought. What type tool are you using, speed ?

Thanks tweinke. I looked at my bot and it looks like you were correct. To small of a radius on the bit. I will regains and try it again. Thanks again for the help.
