Typical water jet cutting machines have a working envelope as small as a few square feet, or up to hundreds of square feet. Ultra-high-pressure water pumps are available from as low as 40,000 psi (280 MPa) up to 100,000 psi (690 MPa). [44] There has also been a growth in small, desktop-sized machines that operate at pressures under 10kpsi.
Robotic Hydrodemolition in Ystad, Sweden. Hydrodemolition of concrete exposing the rebar.. Hydrodemolition (also known as hydro demolition, hydroblasting, hydro blasting, hydromilling, waterblasting, and waterjetting) is a concrete removal technique which utilizes high-pressure water, often containing an abrasive material, to remove deteriorated and sound concrete as well as asphalt and grout.
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 ...
Depending on system size and configuration, waste heat may be transferred by a coolant or directly to air. Water is a commonly used coolant, usually circulated through a chiller or heat transfer system. 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 ...
The many more recently developed processes labeled "machining", such as electrical discharge machining, electrochemical machining, electron beam machining, photochemical machining, and ultrasonic machining, or even plasma cutting and water jet cutting, are often performed by machines that could most logically be called machine tools.
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 ...
