The term abrasive jet refers specifically to the use of a mixture of water and an abrasive to cut hard materials such as metal, stone or glass, while the terms pure waterjet and water-only cutting refer to waterjet cutting without the use of added abrasives, often used for softer materials such as wood or rubber.
Water jet may refer to: A jet of water under pressure, like in an ornamental fountain or drain cleaner; Pump-jet, a marine propulsion mechanism for jetskis and other types of boats; Water jet cutter, a tool for cutting and the machining of engineering materials; Water-jet printer, a printer that makes use of water instead of ink; Dental water ...
The pressurized water acting as a cutting jet can be re-used, with adequate filtering, creating a closed water circuit. [ citation needed ] However, the majority of users do not re-use the water. If more widely used, CryoJet may produce a drastic reduction in the amount of abrasive waste spill currently produced during the water jet cutting ...
Abrasive jet machining (AJM), also known as abrasive micro-blasting, pencil blasting and micro-abrasive blasting, [1] 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.
The Coast Guard's newer cutters, the National Security Cutter, Sentinel-class cutter, and the smaller Marine Protector-class cutter are designed with a stern launching ramp. Stern launching ramps permit the cutters to deploy and retrieve water-jet propelled boats, without first coming to a stop.
A deluge gun, fire monitor, master stream or deck gun is an aimable controllable high-capacity water jet used for manual firefighting or automatic fire protection systems. Deluge guns are often designed to accommodate foam which has been injected in the upstream piping.
The cutting extinguisher technique originates in Sweden, with Cold Cut Systems Svenska AB. [1] [2] Cold Cut Systems Svenska AB was founded in 1988.The origins of the company was in water jet cutting but in cooperation with Räddningsverket (today the Swedish Civil Contingencies Agency (MSB)), the coldcut Cobra cutting extinguisher was developed in the mid-1990s with the first commercial ...
Such cutters are also often referred to by the set-phrase name of single-point cutting tool, as distinguished from other cutting tools such as a saw or water jet cutter. The cutting edge is ground to suit a particular machining operation and may be resharpened or reshaped as needed.
