The origin of ultra-high pressure water cutting
The "discovery" of high pressure water cutting originated in Scotland. After 1 years of experimental research, the industrial high pressure water cutting system appeared.
In p>1936, mining engineers in the United States and the Soviet Union successfully used high-pressure water jet to carry out coal mining and mining. By 1956, the former Soviet Union used water with a pressure of 2bar to cut rocks. In fact, high-pressure water cutting is not a patent, until 1968, when a professor from Columbia University in the United States added abrasives to high-pressure water, the cutting process was accelerated through high-pressure water jet and abrasive grinding.
