1. A processing system of suspension abrasive jets, comprising:
an abrasive suspension container configured to provide a suspension abrasive containing a plurality of abrasive particles, wherein the processing system further comprises the abrasive particles, each of the abrasive particles has an electric charge same as an electric charge of each of the other abrasive particles;
a high pressure source, fluidly connected to the abrasive suspension container and configured to supply a non-aqueous fluid to the abrasive suspension container, wherein the suspension abrasive and the non-aqueous fluid are coupled; and
a nozzle configured to perform a process on a workpiece using the coupled suspension abrasive and non-aqueous fluid, wherein the nozzle has an electric charge same as the electric charge of the abrasive particles.
