    Trouble with cut off operations

    Hi Luuiz, Have you made certain that the tool is at center height? With steel make sure you use plenty of coolant. I would recommend running the lathe at it's slowest speed, (Backgear). Make sure the overhang from the tool post is as short as possible. Martin

    Tapered thread

    Hi, Did you make sure that the taper was the correct angle and the start and end diameters were correct for the thread form? If it is a split die you could try altering the diameter of the die and see if that helps. I would also contact PM Research to check the required diameters. Martin

    Tangential Tool Holder.

    Hi ICEPeter, The metal is mild steel and yes the surface is very rough but that was using a different tool and a rough cut just to reduce the diameter.;) If you look at the end where the new tool holder has cut a small amount off then you can just see that the finish is much smoother. Once...
