Abrasive-jet Machining (AJM) 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.

How to Clean out the water jet abrasive tube. From time to time when using the water jet at Pier 9, the clear tube that feeds abrasive to the head clogs up and stops the water jet from cutting your material. This is usually due to water leaking into the tube which must remain dry for Garnet to flow correctly.
· Abrasive jet machining process cannot be used for machining of soft materials like aluminium. Post machining process, cleaning is required as the abrasive particles tend to get embedded in the workpiece. Once used abrasive particles, cannot be reused as they get deformed. This increases operating costs.
AWJM combines abrasive jet machining with water jet machining (WJM) to create a unique process which overcomes their individual limitations and enhances the machining capabilities of WJM for cutting, drilling, and general cleaning of hard and/or strong materials. In essence it induces material removal by the erosive action of a high-velocity abrasive-laden water jet ejected from a small ...
A tiny speck of dust underneath the jewel in the nozzle will cause the jet to shoot to the side, and cause accelerated wear of the mixing tube. Take the parts to a clean area of your shop, preferably with a sink where you can wash the parts before reassembly. Your waterjet benefits from a clean maintenance area.
What is Abrasive Jet Machining. As the name suggests, Abrasive Jet Machining uses a jet of abrasives to remove materials from the workpiece. Abrasive Jet Machining is also known as Abrasive micro blasting, Pencil blasting, or Micro Abrasive Blasting.. Abrasive Jet Machining is useful to form edge shapes or surface machining …
· Water Jet Machining (WJM) Abrasive Water Jet Machining (AWJM) In WJM, a high velocity jet of pure water (sometimes mixed with stabilizer) is used to erode material. In AWJM, a high velocity jet of water-abrasive mixture is used to erode the workpiece material. Material removal from the workpiece takes place only due to the erosive action of ...
Abrasive water jet cold cutting is a safe (sparkless) means of cutting making it safe for cutting applications in hazardous atmospheres where there is a risk of fire or explosion. This process can cut into all material including cementitious, metallic or rubber linings, coatings or multi-layer composite materials.
1.1 Abrasive jet machining principle:- Abrasive Jet Machining (AJM) is the removal of material from a work piece by the application of a high speed stream of abrasive particles carried in gas medium from a nozzle.
