    Starrett Spindle Square

    $253.00
    SKU: 1289-0600

    Tramming a vertical mill\'s head provides accuracy and convenience and saves a lot of time. It must be done regularly to ensure squareness and perpendicularity between spindle and work surface.Starrett\'s spindle square is easier to use and more precise than the traditional method of tramming with a dial test indicator. It comes fully assembled, with solid steel body with durable black wrinkle finish; two AGD Group 2 dial indicators; and ground gaging surfaces.After setting the spindle square indicators to \"0̦ on a surface plate, place the square into the milling machine\'s collet and bring the head down to the table until both indicator needles have gone approximately one full rotation.The needles do not need to point in the same direction. Identical numerical readings, not needle positions, indicate squareness. To tram the mill, 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.

    Warning:This product may expose you to chemicals including Nickel, Chromium, or Lead, chemicals known to the State of California to cause Birth Defects and/or Cancer. For more information go to www.P65Warnings.ca.gov
