In 1970s, Chinese universities such as Nanjing University of Science and Technology, China University of Mining and Technology began to study ultra-high pressure water jet technology in laboratory, and the initial research direction is mainly used in mining. The mid-1990s began the commercialization of research and application, 1996, the earth water jet self-developed China’s first commercialization of “high pressure water cutting machine CNC universal” come out, known as “China’s first water jet.” During 1996 and 2000, high pressure water jet cutting machine main application areas are stone, ceramic processing and decoration industry, in 2000 after gradually used in stainless steel, glass and other materials cutting. But early due to immature technology, system pressure 300Mpa or less, and product performance instability, market acceptance is not high. Therefore, the period 1996 to 2002, the domestic high pressure water jet cutting machine industry in general is still in the stage of product development and testing applications, most users downstream industries still on the sidelines, marketing process is slow.
