Abstract

A method of punching a small hole in a precision mechanics workpiece, in that the thickness of the workpiece is reduced by the application of pressure in the region where the small hole is to be punched and the material is thereby strengthened, steps being taken to cause the material subjected to pressure to be displaced in the direction of pressure and to yield at right angles hereto. The small hole is punched in the region subjected to pressure at a distance from the edge of that region corresponding at least to the diameter of the small hole, so that the small hole is certain to be punched at a location in that region where the material is strengthened and sound.
