  • Base for setting materials to be processed by NC wire electro-spark processing machine
    Patent number: 4757178
    Abstract: A base on a movable table is used for determining the x and y coordinates of a workpiece. The base consists of a first reference base and a second reference base, with each reference base having a reference face with grooves adapted to receive a wire to determine the location of the side of the workpiece in one coordinate direction and two reference holes having wire guiding grooves for checking the thermal expansion of the side of the workpiece. Additionally each reference base has an indicator for showing both the distance between the two reference holes and the distance between the centers of the two reference holes and the reference face.
