The development history of water cutting machine
In recent years, the "CNC ultra-high pressure water cutting machine" (also known as water jet) has gradually entered a rapid growth period with the maturity of the product and the expansion of the application area, relying on a large-scale CNC platform with higher precision and greater power, Higher pressure high-pressure systems, five-axis and six-axis control systems, slope and self-correcting cutting, water cutting and tool processing, and other new technology applications, expand the application of water cutting technology to a wider range of metals and non-metals ( And food) processing and industrial manufacturing. The combination of cutting and processing increases the processing efficiency and value from cutting materials to processing semi-finished products and finished parts, making it easy to solve the cutting and processing problems of multi-variable, large and complex structural parts and difficult-to-process materials.
Ultra high pressure water cutting—new cold cutting technology Water cutting is a cold cutting technology based on the application of ultra high pressure water jets. Compared with thermal cutting (such as flame, plasma, laser, etc.), "water jet" can cut almost all materials from soft to hard, especially metals with a thickness of 20mm or more, carbon fiber, titanium alloy, aluminum alloy, honeycomb structure and composite In the forming and processing of materials, it has become an internationally recognized ideal processing method.
Water cutting technology has been widely used in the processing of steel, copper and aluminum, glass, ceramics, cemented carbide, plastics, man-made fibers, cloth, paper, composite materials, etc., and can be directly made into structural parts or welded parts. The water cutting system has become a new type of manufacturing equipment for aerospace, military industry, rail transit, shipbuilding, automobiles, engineering machinery, light industry, chemical industry, energy, construction engineering and other industries.
The current status and trends of development at home and abroad began in the 1960s. The United States, Germany, Japan, Russia, etc. have invested heavily in research and development of ultra-high pressure generation systems and injection systems until the 1990s. The ultra-high pressure water cutting system is gradually commercialized. Internationally representative companies include FLOW, KMT, and OMAX. At present, the highest cutting pressure can reach 600MPa. my country has carried out research on ultra-high pressure water cutting technology for nearly 40 years. At present, the general operating pressure of domestic commercial water cutting equipment is generally around 220 MPa—400 MPa. There are dozens of products in general-purpose CNC ultra-high pressure water cutting machine tools in finalized production. In compiling the national standard of "Numerical Control Water Cutting Machine", its product level has reached the international advanced level. At the same time, intelligent products such as five-axis linkage waterjet cutting machines, robotic waterjet cutting machines, large-scale CNC waterjet cutting machine tools, and waterjet machining centers have rapidly popularized and expanded the application fields of my country's ultra-high pressure waterjet technology.
