Abstract
Blades for disintegrating machines and the like, essentially characterized by the fact that in an annealed steel sheet a general die cut is used to obtain smooth edges: a milling with an abrasive wheel of the aforementioned edges, operating in a direction perpendicular to them and obtaining, in certain fractional amplitude with respect to the total of the edge, a series of elementary edges defined in each fraction by the work of the aforementioned tool, resulting between each elementary edge nerves resistant to the bending of the same, and finally a work of hot stamping , operating at temperatures between 750 to 850 degrees Celsius to use the remaining heat as tempering temperature.
