Abstract
The machining liquid includes a load of particles contained in a dielectric liquid. The particles are carbon microfibers, sectioned or not, having a diameter (e) comprised between 0.2 and 8 micrometers and a length which is a function of the machining gap (G) provided between the electrode-tool and the electrode-workpiece. 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.
