Parting and Grooving
A parting tool is deeper and narrower than a turning tool. It is
designed for making narrow grooves and for cutting off parts.
When a parting tool is installed, ensure that it hangs over the
tool holder enough that the holder will clear the workpiece (but
no more than that). Ensure that the parting tool is perpendicular
to the axis of rotation and that the tip is the same height as the
center of the part. A good way to do this is to hold the tool
against the face of the part.
Set the height of the tool, use a tool setting gauge or dead
center mounted in the tailstock.
When the cut is deep, the side of the part can rub against sides
of the parting tool, so it's especially important to apply cutting
fluid. Parting and grooving are generally done at lower speed
and feed rates.
