Dr. Norman Franz has always been recognized as the father of waterknives. He was the first person to study ultra-high pressure (UHP) waterjet cutting tools. The definition of ultra-high pressure is above 30000 psi. Dr. Franz is a forestry engineer who is looking for a new method to cut large tree trunks into wood. In 1950, Franz placed a heavy object on a water column for the first time, forcing the water to pass through a small nozzle. He obtained brief high-pressure jets (exceeding the current pressure multiple times) was able to cut wood other materials. His later research involved more continuous water flow, but he found it very difficult to obtain continuous high pressure. Meanwhile, the lifespan of the parts is also measured in minutes, rather than weeks or months.

Dr. Franz has never produced a mass-produced wood cutter. However, wood cutting is one of the least important applications of ultra-high pressure technology. But Dr. Franz proved that high-speed converging water flow has great cutting energy - the application of this energy far exceeds Dr. Franz's dream. In 1979, Dr. Mohamed Hashish worked at the Fulu Research Laboratory began researching methods to increase the cutting energy of waterjet for cutting metals other hard materials. Dr. Hashish is widely recognized as the father of sing waterknives, as he invented the method of adding s to ordinary waterknives. He used garnet (a commonly used material on spaper) as the s material. With this method, waterjet (containing s) can cut almost any material. In 1980, sblasting water knives were first used for cutting metal, glass, concrete. In 1983, the world's first commercially available sing waterjet cutting system was introduced used for cutting automotive glass. The first users of this technology were the aerospace industry, who discovered that waterjet was an ideal tool for cutting stainless steel, titanium, high-strength lightweight synthetic materials, carbon fiber composite materials used in military aircraft (already used in civilian aircraft). Since then, sblasting water knives have been adopted by many other industries, such as processing plants, stone materials, ceramic tiles, glass, jet engines, construction, nuclear industry, shipyards, so on.

The rise of technology

At the end of the 20th century, water cutting technology was introduced to China has undergone years of market application equipment improvement. It is mainly used in industries such as building ceramics, stone, metal processing, automotive industry, aerospace, military industry, petrochemical industry, has achieved good development. In the early 21st century, portable water cutting technology emerged in response to the related problems technological singularity in the market application of water cutting technology. Portable water cutting technology belongs to low-pressure water jet technology, which can achieve cutting operations of metals other materials using lower pressures (25 Mpa~50 Mpa). The emergence of this technology has strong practical application significance. The birth of portable water cutting technology has opened a historic page for the development of water cutting technology, which is another breakthrough in the field of water cutting technology marks the entry of water cutting technology into the research stage of portable water cutting technology. The portable water cutting technology draws on the basic principles of water cutting technology has undergone technological reform innovation, aboning the post hybrid cutting principle of traditional water cutting technology. At the initial stage, this technology was mainly applied to the destruction disposal of dangerous goods such as ammunition. With the continuous improvement of portable water cutting technology, its application field has also been further exped, mainly used in explosion disposal, petrochemical industry, coal mine underground operation, engineering construction, shipbuilding other related industries
