RESEARCH ON INCREASING ACTIVE LIFE OF CUTTING TOOLS

Abstract

At the exploitation of dies the defections that occur, due mainly to non operating rules of exploration, the improperly conditions of the machine (press) in terms of cinematic precision and the wearing elements in relative motion (ram displacement, wearing guides, etc) as the incorrect mounting of dies on the press. When installing dies must consider several aspects. Among the techniques used, especially for restoring the active elements in the work area are rectified frontal surfaces, hard chromating, hardening with electric sparks and charging welding. Were restored active profile and size of the work active elements so after reconditioning they corresponded in terms of dimensional precision and resistance to wear, like initial elements
