Abstract: A process for producing a steel punching sheet that has the same ideal dimension over the entire length of the punching edge has the following steps: producing webs carrying punching edges on a steel starting sheet; processing the punching edges, wherein the distance between the punching edges and the back of the sheet is adjusted to a positive tolerance with respect to an ideal dimension; and grinding the back of the sheet to remove material in excess of the ideal dimension to within a tolerance of not more than 0.02 mm, more particularly a tolerance of not more than 0.005 mm. Advantageously, the process includes the following additional steps: adjusting the distance between the punching edges and the back of the sheet to a negative tolerance, with respect to an ideal dimension, and applying material to the back of the sheet to make-up for the negative tolerance up to a positive tolerance of not more than 0.02 mm, more particularly, a tolerance of not more than 0.
