Load of particles for machining liquids for electro-erosion machines, its process of production, its use and machining liquid containing such a load

Abstract

The machining liquid (7) comprises a load (9) of particles contained in a dielectric liquid (8). The particles are carbon microfibers (10), sectioned or not, having a diameter (e) comprised between 0.2 and 8 micrometers and a length (l) which is a function of the machining gap (G) provided between the electrode-tool (5) and the electrode-workpiece (6). Thanks to this load of carbon microfibers of well-defined dimensions and geometry, the electro-erosion output, the precision of machining, the condition of the surface obtained and the ability to replicate machining performances, are considerably improved.
