<p>A producing method for grater includes: coating the electrolyzing resistant layers (4, 5) on the front and rear surfaces of a metal plate (1), providing openings (4a, 5a) in the electrolyzing resistant layers (4, 5) on the front and rear surfaces according to a cutting shape, the opening (5a) on the rear surface being larger than the opening (4a) on the front surface, putting the metal plate (1) into a electrobath (101), two electrodes of DC connecting to the metal plate (1) and electrolyte, and the electrolyte etching the exposed area on the metal plate (1), thereby forming the cutting shape. A producing device for grater has a electrobath (101), rollers (103) for transferring a workpiece (102) are positioned in the electrobath (101) and nozzles (104) are provided on one side or both sides of the rollers (103), two electrodes of DC are connected to the workpiece (102) and electrolyte. The method and the device can enhance the edge precision of the grater.</p> |
