    Starrett Spindle Square

    The Starrett 649 Series Spindle Square offers accuracy, convenience
    and significant time saving with the common shop task of tramming
    the head of a vertical milling machine. This must be done regularly to
    ensure squarness and perpendicularity between the spindle and work
    surface.
    The spindle square is easier to use and more precise than the
    traditional method of tramming with a dial test indicator.


    Using the Spindle Square


    After setting the spindle square indicators to “0” on a surface plate,
    place the Spindle Square into the collet of the milling machine and
    bring the head down to the table until both indicator needles have
    rotated approximately one full rotation.
    The needles do not need to point in the same direction. Identical
    numerical readings, not the needle positions, indicate squareness.
    To tram the milling machine, adjust the machine per normal
    procedures until both indicators read the same numerical value. After
    setting the X-axis, repeat the same procedure with the Y-axis.
