1. , a kind of method of direct forming tool die by multiple etchig, it comprises selects the sheet metal step;

  • It is characterized in that also being provided with after the described selection sheet metal step;

    the press mold step, step of exposure, development step, etching step, stripping step, close etching step and the polishing step that the Photoresist film are pressed on the sheet metal one side;

    Utilize the press mold step and with the cutting die egative film of making expose and development step image is transferred on the Photoresist film;

    Etching step carries out etching first time for the light shield protective film spray at the cutting line position that press mold, exposure and the back of developing kept with the atomizing etching solution, and presses the spray pressure and the angle of the height control etching solution of required cutter wall;

    The stripping step is peeled off rapidly the light shield protective film on the cutting line for utilizing water spray;

    The close etching step is to remove both sides, top, cutter wall top crest line with the etching solution of a small amount of atomizing, makes blade form the angle roundlet arc knife edge that contracts;

    Polishing step makes movable right cylinder bristle carry out polish-brush and polishing in cutter wall and susceptor surface high speed play for utilizing magnetic force, with the shaping cutting die.
