Fine Blanking: allows much higher results mainly in Dimensional Tolerance; Flatness of the piece; Quality of cutting finish (cut without tearing).
Fine blanking parts are characterized by extremely precise, rectangular crack and tear-free cut surfaces. These precision parts are manufactured with the tightest tolerances, great angular accuracy and the best possible flatness. A complex design is possible through the integration of different forming processes in the tool.
The metal stamping consists of a process of machining without starting of shaving where the steel sheet is cut by means of presses for the achievement of certain metallic pieces. For this in the presses the dies are placed with the necessary operations.
The basic elements of a die are the punch having the shape and dimensions of the hole to be made, and the cutting die whereby the die is inserted when it is forcefully driven by the power provided by the press through a Eccentric drive that generates a dry and forceful blow on the sheet, producing a clean cut of the same.
