    Parting tool chatter

    Baronj wrote, "That looks reminiscent of the sort of method used on auto or CNC tool changers. However it doesn't get you away from the play in the cross slide. " I agree with you Baronj but the main point of the vertical parting tool is it avoids the horizontal cantilever distance from the...

    Parting tool chatter

    What about this "vertical" parting tool arrangement. The topslide has been wound back just enough to enable the parting tool holder to rest solidly on the cross slide, preventing any downward deflection due to the normal cantilever extension on both a front or rear mounted parting tool. The...

    Parting tool chatter

    In order to clarify the operation of a vertical parting tool here is my rather primitive description of how I think it works. Imagine that you are the parting tool holder whereby your two hands are held straight out from you body. You hands are gripped together and your fists are the cutting...

    Keyway cutting inthe lathe

    Show Us Your Lathe

    Here is my old lathe a Chipmaster, circa 1956 and which, I have refurbished and repainted. The bed was fairly well worn so I spent some time trying to re finish the bed by hand to achieve most of its original accuracy. I have added tee slots (bolted from underneath to the original cross slide)...
