Description

technical field [0001] The invention relates to the technical field of electrical processing, in particular to a particle-reinforced metal matrix composite material processing device and processing method. Background technique [0002] Particle reinforced metal matrix composites have many advantages such as high specific strength, high specific modulus, low density, wear resistance, heat resistance, no moisture absorption, radiation resistance, and small thermal expansion coefficient. Therefore, it has a wide range of applications in engineering fields such as aerospace, ships, automobiles, military, and electronics. However, the hardness of the reinforcement phase particles in the particle-reinforced metal matrix composites is relatively high, which is a typical difficult-to-machine material, especially in the processing of deep and small holes. When using traditional machining methods to process particle-reinforced metal matrix composites, because machining is a contact p...

Problems solved by technology

However, in the actual EDM, the size of the particle phase is uneven, and the electrodes such as slotting, edge trimming and polygon have limited chip removal ability for larger-scale particle phases. In addition, as the processing depth increases, the gap between electrodes The chip removal and renewal ability of the working fluid are sharply weakened, and the inter-electrode state is more harsh. The effect of improving processing efficiency, improving processing quality and reducing electrode loss is not obvious, which restricts particle reinforced metal matrix composites to a certain extent.
