Definitions

  • the invention relates to a method for deburring metallic and non-metallic workpieces.
  • the blasting medium With blasting deburring, the blasting medium is accelerated with the help of compressed air or blast wheels and the workpieces are loaded with it.
  • the invention is therefore based on the object of developing a method for deburring workpieces, in particular those with irregular spatial shapes, in which the deburring action can be metered in such a way that its action is sufficient on the one hand and no workpiece damage occurs on the other hand.
  • the object is achieved according to the invention in that the workpieces are exposed to an electromagnetic rotating or traveling field together with a ferromagnetic deburring agent within a closed non-ferromagnetic and electrically non-conductive container such that the deburring agent is applied to the workpieces and thereby deburred.
  • Particularly suitable deburring agents are ferromagnetic metal powders, wire sections made of VA steel from e.g. 1 mm length and 1 mm diameter, ball polishing body made of steel from e.g. 10 mm in length and 1 mm in diameter or a mixture of ferromagnetic bodies and non-ferromagnetic, abrasive additives, e.g. ceramic grinding powder.
  • FIG shows a schematic representation of a suitable device with which the inventive method can be carried out.
  • a container 11, e.g. made of plexiglass, is arranged on a linear motor 14. Inside the container 11 are the workpieces 12 to be deburred, e.g. Injection molded parts, and the deburring agent 13, e.g. a fine-grained metal-6 powder.
  • the traveling field direction of the linear motor is indicated by arrow 1.
  • the metal powder 13 is moved and swirled by the electromagnetic traveling field which reaches through the plexiglass container 11. These movements of the metal powder 13 are to be indicated by the arrows 15.
  • the workpieces 12 are loaded with the metal powder 13 and slowly rolled over.
  • the swirling of the deburring means 13 and thus the deburring effect can be varied by the size of the field-generating tension.
  • the deburring means 13 is always kept in a whirling motion, so that even small burr-like openings in the workpieces are gradually deburred.
  • the method according to the invention shows a clear superiority over the known methods, since the magnetic field, which produces the movement and swirling of the active medium, is also effective at hidden places and swirls the active medium there and thus produces a deburring effect.
  • Another advantage of the method according to the invention is that manual post-processing is not required.
