equipment. ajm machines are usually self-contained bench-top units. first it compresses the gas and then mixes it with the abrasive in a mixing chamber. the gas passes through a convergent-divergent nozzle before entering the mixing chamber, and then exits through a convergent nozzle. the nozzle can be hand held or mounted in a fixture for automatic operations.
the water jet system's cutting head restricts the water flow to generate pressure and direct it onto the workpiece. a holding tank, called a hydraulic accumulator, is used to reduce pressure vibrations at the output end. the more recently developed parallel hydraulic intensifier also uses oscillating pistons to compress water. however, these .
a water cannon is a device that shoots a high-velocity stream of water. typically, a water cannon can deliver a large volume of water, often over dozens of meters. they are used in firefighting, large vehicle washing, riot control, and mining.most water cannons fall under the category of a fire monitor
a laser microjet is a water-jet guided laser in which a pulsed laser beam is coupled into a low-pressure water jet. this is used to perform laser cutting functions while using the water jet to guide the laser beam, much like an optical fiber, through total internal reflection.
water jet cutter: also known as a 'waterjet', is a tool capable of slicing into metal or other materials such as granite by using a jet of water at high velocity and pressure, or a mixture of water and an abrasive substance, such as sand. it is often used during fabrication or manufacture of parts for machinery and other devices. waterjet is .
today other forms of metal cutting are becoming increasingly popular. an example of this is water jet cutting. water jet cutting involves pressurized water in excess of 620 mpa 90 000 psi and is able to cut metal and have a finished product.
the use of a cutting extinguisher is a fire extinguishing technique that combines abrasive waterjet cutting with water spray extinguishing, through a single handpiece or nozzle. the fire-fighter approaches the fire from outside the main fire area, then uses the cutting action to drill a small hole through a door or wall.

the water jet combined with an abrasive cutting sand makes it possible to 'shoot' right through a wall or other structure. when the water jet has penetrated the fine water droplets in the water jet hits the hot fire gases in the fire room and are turned to steam.
very little of the cutting in an awj is accomplished with the water. however when you are cutting food, it is best to not distribute a bunch of abrasive into the food. additionally, food tends to not be very difficult to 'machine' meaning you don't need to mess with all the hassles of abrasive. as a result, a plain waterjet is used.
a 5-axis water jet cutter and a part manufactured with it. multiaxis machining is a manufacturing process that involves tools that move in 4 or more directions and are used to manufacture parts out of metal or other materials by milling away excess material, by water jet cutting or by laser cutting .
cryojet / icejet is a derivative of the machining process called abrasive waterjet machining. cryojet/icejet technology uses ice particles made of water coming from a running water or freshwater system to cut material. while the ice particles are cutting material, they melt and go into the water tank of the machine. the pressurized water acting as a cutting jet can be re-used, with adequate filtering, creating a closed water circuit. however, the majority of users do not re-use the water. if mor
