What Is Abrasive Jet Machining?
Began application in the United States in the early 1950s. A certain pressure (2-13 MPa) of gas (air, nitrogen or carbon dioxide) and abrasive powder (10-50 microns in diameter) are mixed and ejected at high speed from a small orifice of a nozzle with a diameter of 0.1 to 1.2 mm. Destructive action removes material from the workpiece.

- Abrasive blast processing Link Link title corundum or silicon carbide abrasives are generally used, and sometimes glass beads (for surface polishing) and sodium bicarbonate (for surface cleaning) are used. The nozzle hole material is made of hard alloy or sapphire. The nozzle is generally made into a pen handle type, which is convenient for manual operation. The nozzle can also be installed on a fixture, and the model guide, scale guide or other control devices are used for automated mass production. Abrasive spray processing is mainly used for: cutting thin sheets of glass, quartz, germanium, silicon, gallium, mica, tungsten, and titanium alloys, or making narrow grooves and making small holes; roughening the surface of glass; from the surface of parts Remove dirt, impurities, oxide layers, insulation layers or other coatings and platings, and remove burrs; Fine-tune the resistance and capacitance of integrated circuits.
