GRAPHITE FOR EDM PROCESSING<\/strong><\/p>\n\n\n\n

It is used in engineering for the production of working parts of molds (matrices and punches) on electroerosive piercing machines as electrodes, which repeat the profile of the required part. The principle of shaping is to break down the metal layer under the influence of a high voltage electric current passing through the graphite electrode and then removing the slag from the cutting zone. Created shape in the metal corresponds to the shape of the electrode tool.<\/p>\n\n\n\n
