Abstract

The invention provides a multichannel discharging, atomizing, ablating and grinding compound processing method. The multichannel discharging, atomizing, ablating and grinding compound processing method is characterized in that multiple hollow copper pipe electrode bundles which are insulating from one another are made into the required shape, a resistor is connected into the electricity inlet endof each copper pipe electrode, and the copper pipe electrodes are connected with a pulse power supply as a whole to generate multichannel discharging; then, resin adhesive liquid mixed with abrasive particles is used and flows into gaps between the different copper pipe electrodes, and a multichannel discharging electrode, namely, a discrete electrode, with a grinding effect is obtained through solidification forming. Discharging, atomizing, ablating and grinding compound processing is conducted through the electrode, simultaneous multipoint discharging is achieved in the processing area, andtherefore discharging energy can be dispersed and multipoint induced ablating reaction is formed; the metal combustion range of the processing area is widened so that efficient corrosion removing canbe achieved; and secondly, by means of the abrasion effect of the abrasive particles in the electrode, oxide and softened layers on ablating processing surfaces are removed through abrasion, and new base bodies are exposed. By means of the multichannel discharging, atomizing, ablating and grinding compound processing method, the continuity of ablating processing, the utilization rate of valid pulses, the ablating efficiency and the surface quality can be improved, and the contradiction between the processing efficiency and the processing quality is resolved.

AI Technical Summary

Problems solved by technology

Since this processing method is essentially single-channel EDM, only one discharge channel between the two electrodes can induce activation at the same time, and the range of ablation area is limited, which is not conducive to the further improvement of ablation processing efficiency.

The ablation combustion reaction will form an oxide layer on the processed surface. These metal oxides are generally not conductive and flammable, which not only reduces the utilization rate of spark discharge, but also makes it difficult to form combustion, making ablation processing unsustainable.
