ABRASIVE JET MACHINING Definition: In abrasive jet machining, a focused stream of abrasive particles, carried by high pressure air or gas is made to impinge on the work surface through a nozzle and the work material is made to impinge on the work surface through a nozzle and work
The basic working principle employed in abrasive jet machining is shown in the above figure. This method utilizes high speed stream of abrasive particles which are carried by a high pressure air or gas on the work material through a nozzle device.
Waterjet machining utilizes a high pressure stream of water to erode a narrow line in the stock material. It has the ability to cut almost any material while maintaining high precision. To cut a wider range of materials from tool steel to titanium to foam, a granular (typically garnet) abrasive is added to the waterjet, increasing the cutting ...
Abrasive Jet Machining
Water jet machining uses water mixed with abrasive materials projected with high pressure (typically 0.7 MPa) and focused on the workpiece. • Powder blasting, or abrasive jet machining, is a technique in which a particle jet (typically Al 2 O 3 particles of 3–30 μm) is directed toward a target for mechanical material removal. It is a fast ...
abrasive water jet with significant velocity of 800 m/s. Such high velocity abrasive jet can machine almost any material. Fig. 1 shows the photographic view of a commercial CNC water jet machining system along with close-up view of the cutting head. Fig. 1 Commercial CNC water jet machining system and cutting heads
Apr 06, 2016· In abrasive-jet machining (AJM) material is removed by the impact of a high velocity stream of gases and abrasive mixture focused on to the workpiece. High Velocity impact of an abrasive particle causes a tiny brittle fracture on the work surface and the flowing gases carries away the dislodged small workpiece particle.
Abrasive jet machining (AJM) is one of the modern machining processes where high velocity jet of abrasives mixed with dehumidified pressurized gas is made to impinge the work surface, which in turn removes material by mechanical erosion.
A water jet cutter, also known as a water jet or waterjet, is an industrial tool capable of cutting a wide variety of materials using a very high-pressure jet of water, or a mixture of water and an abrasive substance. The term abrasive jet refers specifically to the use of a mixture of water and abrasive to cut hard materials such as metal or granite, while the terms pure waterjet and water ...
Abrasive jet machining (AJM) utilizes a high velocity jet of abrasives to remove material from work surface by impact erosion. Get an overview of AJM process, mechanism, parameters, equipment, MRR, accuracy, capability, pros and cons, applications, controlling, etc.
Standard Rapid Water Level Control for cleaner, safer, and quieter submerged cutting completes most work below 80 dBA Standard 600 lb Bulk Abrasive Delivery System transports garnet from the assembly's large hopper into the Zero Downtime Hopper located on the Z-Axis Optional Tilt-A-Jet taper eliminating abrasivejet cutting head
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),also known as abrasive micro-blasting, pencil blasting and micro-abrasive blasting. AJM is an abrasive blasting machining process that uses abrasives propelled by a high velocity gas to erode material from the workpiece.
Abrasive Jet Machining. Abrasive jet machining uses a water jet cutter capable of slicing into metal or other materials using an extremely high pressure stream of water and abrasive materials. This water jet machining process is essentially the same process as naturally occurring water erosion, but it occurs much more quickly and forcefully.

Abrasive Jet Machining Definition: The Abrasive jet machining is the process of impinging the high-speed stream of abrasive particles by high-pressure gas or air on the work surface through a nozzle and metal removal occurs due to erosion caused by high-speed abrasive particles.
May 20, 2017· Water Jet Machining (WJM) also called water jet cutting, is a non-traditional machining process in which high-velocity jet of water is used to remove materials from the surface of the workpiece.WJM can be used to cut softer materials like plastic, rubber or wood. In order to cut harder materials like metals or granite, an abrasive material is mixed in the water.
Abrasive water jet machining Ultrasonic machining. Difference between grinding and milling The abrasive grains in the wheel are much smaller and more numerous than the teeth on a milling cutter. Cutting speeds in grinding are much higher than in milling.
