Abstract

A process is disclosed for hardening the cutting edges of saws, knives and cutting tools, in particular for processing wood, paper, cardboard, plastic materials, leather and textiles, by means of an energy beam guided over the areas to be hardened of the tool. In order to obtain optimal hardness, a plasma beam is used as energy beam. The plasma beam (2) is guided with a relative speed (v) with respect to the cutting edge of the tool between 5 and 100 mm/sec., the gap between the outlet nozzle of the plasma torch (1) and the cutting edge extends between 2 and 14 mm, the power of the plasma beam is comprised between 1 and 10 kW, and the diameter (d) of the outlet nozzle of the plasma torch (1) is comprised between 3 and 7 mm.
