A method for producing a master plate and a master plate produced by this method which has highly accurately disposed fitting bores or fitting pins at prespecified coordinate intervals in order to form a precise grid system. The master plate serves to produce clamping plates identical to it for use in machining workpieces or building machinery. The fitting bores in the master plate are derived from insertable fitting sleeves which have a smaller diameter than preliminary bores disposed at the grid intervals in the foundation plate and are measured in their final position, preferably using measuring gauges having a zero dimension tolerance in the desired distance. After the location by measurement, the insertable fitting sleeves are pre-fixed, preferably via end flanges mechanically connected with the contact face of the foundation plate, and once all the insertable fitting sleeves have been pre-fixed (subsequent sleeves being positioned via the zero-dimension measuring gauges relative to previous pre-fixed fitting sleeves), all the fitting sleeves are fixed in final position by the introduction of a settable plastic material. |
