In abrasive jet machining (AJM) a focused stream of abrasive grains of Al 2 O 3. or SiC carried by high-pressure gas or air at a high velocity is made to impinge on the work surface through a nozzle of 0.3- to 0.5-mm diameter.The workpiecematerial is removed by the mechanical abrasion (MA) action of the high-velocity abrasive particles. The fundamental principle of Abrasive jet machining involves the use of a high-speed stream of abrasive particles carried by a high-pressure gas or air on the work surface through a nozzle. In Abrasive jet machining abrasive particles are made to impinge on work material at high velocity. The use of abrasive water jet for machining originated almost 30 years ago with the abrasive water jet cutting the metals without heat (Dobbins, n.d.). Drain and Catcher. variables in ajm. The metal is removed due to erosion caused by the abrasive particles impacting the work surface at high speed. The process makes use of an abrasive jet with high velocity, to remove material and provide smooth surface finish to hard metallic workpieces. velocity It also provides information about the largest garnet abrasive manufacturers and exporters in India, like VV Mineral. As Abrasive jet machining (AJM) is similar to sand blasting and effectively removes hard and brittle materials. The waterjet stream, moving at nearly three times the speed of sound, can penetrate almost any material and thickness. High velocity stream of abrasive is generated by converting the pressure energy of the carrier gas or air to its kinetic energy and hence high velocity jet. Looks like you’ve clipped this slide to already. Nozzle life is limited (300 hours) 7. AJMM is a promising technique to three-dimensional machining of glass and silicon in order to realize economically viable micro-electro-mechanical systems (MEMS) It employs a mixture of a fluid (air or gas) with abrasive particles.
