Abstract

The present disclosure provides a processing method of suspension abrasive jets, and the method comprises the following steps. Provide a workpiece on the processing machine. A suspension abrasive containing a plurality of abrasive particles with the same electrical property is provided in an abrasive suspension container. A non-aqueous fluid is supplied to the abrasive suspension container from a high pressure source. The workpiece is machined by jetting a suspension abrasive jet that couples a suspension abrasive and the non-aqueous fluid from a nozzle. The suspension abrasive and the non-aqueous fluid of the suspension abrasive jet are respectively recycled to the abrasive suspension container and the high pressure source by an abrasive separation and recycling device after the process.

First claim

What is claimed is:

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.

2 . The processing system of suspension abrasive jets according to claim 1 , wherein the abrasive suspension container has a flat bottom contour.

3 . The processing system of suspension abrasive jets according to claim 1 , wherein the nozzle has a diameter, a ratio of the diameter of the nozzle to a diameter of each of the abrasive particles is between 3 to 20.

4 . The processing system of suspension abrasive jets according to claim 1 , wherein the processing system further comprises the suspension abrasive, the suspension abrasive with a Mohs scale of mineral hardness of 9 or more is selected.

5 . The processing system of suspension abrasive jets according to claim 1 , wherein the processing system further comprises the suspension abrasive, the suspension abrasive is selected from silicon carbide, diamond, graphene, boron carbide, zirconia, corundum, tungsten carbide, titanium carbide, quartz, boron, boron nitride, rhenium diboride or titanium diboride.

6 . The processing system of suspension abrasive jets according to claim 1 , wherein the high pressure source is configured to supply the non-aqueous fluid at a pressure greater than 10,000 psi.

7 . The processing system of suspension abrasive jets according to claim 1 , wherein the processing system further comprises the suspension abrasive and the non-aqueous fluid, a concentration of the suspension abrasive relative to the non-aqueous fluid is configured to be between 5.0 g/l-30.0 g/l.

8 . The processing system of suspension abrasive jets according to claim 1 , wherein the processing system further comprises the suspension abrasive and the non-aqueous fluid, a ratio of a volume flow rate of the suspension abrasive to a volume flow rate of the non-aqueous fluid in the suspension abrasive jet is configured to be between 35% and 65%.

9 . The processing system of suspension abrasive jets according to claim 1 , further comprising:
a paddle component disposed in the abrasive suspension container.
