Abrasive jet machining (AJM), also known as abrasive micro-blasting, pencil blasting and micro-abrasive blasting, is an abrasive blasting machining process that uses abrasives propelled by a high velocity gas to erode material from the workpiece. Common uses include cutting heat-sensitive, brittle, thin, or hard materials.
Various applications of Abrasive Jet Machining (AJM) Process are enumerated in this article. Applications include surface cleaning, coating removing, deflashing, trimming, engraving, deburring, drilling, parting, ceramic abrading and glass frosting, etc.
Meaning of Abrasive Jet Machining (AJM): In this process a focused steam of abrasive particles (of size 10 to 40 microns) carried by high pressure gas or air at a velocity of about 200 to 400 m/sec is made to impinge on the work surface through a nozzle, and the work material is removed by erosion by the high velocity abrasive particles.
This page is about the meanings of the acronym/abbreviation/shorthand AJM in the Miscellaneous field in general and in the Unclassified terminology in particular. Abrasive Jet Machining Miscellaneous ?
Abrasive Jet Machining (AJM): In AJM, the material removal takes place due to the impingement of the fine abrasive particles. These particles move with a high speed air (or gas) stream. Figure 6.1 shows the process along with some typical parameters of the process. The abrasive particles are typically of 0.025 mm diameter and the air discharges
In this post, you learn abrasive jet machining its working principle, parts, applications, advantages and disadvantages.. Working Principle of Abrasive Jet Machining . 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 (AJM), abrasive particles are made to impinge on the work material at a high velocity. The jet of abrasive particles is carried by carrier gas or air. The 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.
Examples of such processes include abrasive jet machining (AJM), water jet machining (WJM), abrasive water jet machining (AWJM) and ultrasonic machining (USM). In abrasive jet machining, abrasive particles are first mixed with the compressed gas at a pre-defined mixing ratio.
Introduction To AJM: Abrasive Jet Machining (AJM) is Non conventional machining the removal of material from a workpiece by the application of a high speed stream of abrasive particles carried in gas medium from a nozzle. The AJM process differs from conventional sand blasting in that the abrasive is much finer and the process parameters and cutting action are carefully controlled.
Abrasive jet machining (AJM) is a manufacturing technology based on erosion localization and intensification. AJM has a progressively important influence on the machining technology market. Over the past 20 years, there has been an exponential growth in the number of limestonethat discuss AJM.
Read: Abrasive Jet Machining (AJM) working principle and process parameters Applications of abrasive jet machining. AJM is suitable for machining heat sensitive material like silicon, gallium because the heat generation during the machining is very low.; Ajm can be used for cleaning purposes.
Abrasive Jet Machining Services Pty Ltd was established in 1998 and is now one of the leading and most experienced independent water jet cutting and fabrication companies in Australia. AJM is an Australian privately owned and operated company with facilities located in South East Queensland.

Conclusion-: The better performance, and the applications presented above statements confirm that ABRASIVE JET MACHINING (AJM) will continue to expand. From operator experiences the abrasive jets are capable of anywhere from 0.5mm-0.025mm precision. Newer machines are capable of 3D machining thus making it an important in specialty manufacturing.
Mar 29, 2017 Abrasive jet machining is a non-traditional machining process which is mostly used in machining of hardened metals. In this machining process a focus stream of abrasive particles are forces to impinge on work piece at high velocity. These high velocity abrasive particles remove metal by brittle fracture or erosion from work piece.
ABRASIVE JET MACHINING (AJM) In Abrasive Jet Machining (AJM), abrasive particles are made to impinge on the work material at a high velocity. The high velocity abrasive particles remove the material by micro-cutting action as well as brittle fracture of the work material.
Abrasive Jet Machining (AJM) or Micro Blast Machining is a non-traditional machining process, wherein material removal is effected by the erosive action of a high velocity jet of a gas, carrying fine-grained abrasive particles, impacting the work surface. The process is particularly suitable to cut intricate shapes in hard and brittle materials
AJM is applied for many applications like cutting, cleaning, polishing, deburring, etching, drilling and finishing operation. In Abrasive jet machining abrasive particles are made to impinge on work material at high velocity. Jet of abrasive particles is carried by carrier gas or air.
Process parameters of Abrasive Jet Maching (AJM) are factors that influence its Metal Removal Rate (MRR).. In a machining process, Metal Removal Rate (MRR) is the volume of metal removed from a given workpiece in unit time. The following are some of the important process parameters of abrasive jet machining:
