Abstract
A method and an apparatus for vertically calibrating a wire of a wire cutting electric discharge machine are provided. The vertical calibration apparatus includes a body, an upper calibration board and a lower calibration board attached to the body and parallel to a machine table, with a circular hole formed through the upper calibration board and on the lower calibration board respectively. The two circular holes are coaxial and have different diameters. The method of wire vertical calibration includes searching for the circle centers of the two circular holes by contacting the circles several times with the wire in a prescribed manner, then passing the wire through the circle centers. The method and apparatus allow wire vertical calibration to be more easily and accurately performed.
