Abrasive vs pure water cutting
What is the difference between abrasive and pure waterjet cutting?
Although in practice, high-speed water flow is used to cut the material, in pure water cutting, water is the cutting tool. In abrasive water cutting, high pressure water is used to accelerate abrasive particles, and abrasive particles play a cutting role in practice.
Abrasive water jet cutting uses abrasive particles (such as garnet) to add high pressure water, and cutting hard materials. Add abrasive particles to water in the nozzle of water jet cutting machine. In this operation, the abrasive particles are actually cutting the material. The role of the water is to accelerate the abrasive particles to a speed suitable for cutting and to direct the abrasive particles to the selected cutting point.The cutting effect can be improved by increasing the water pressure to accelerate the water and particles to higher speeds, or by increasing the flow of water and particles to increase the impact rate of particles on the material. Abrasive waterjet cutting is ideal for harder or thicker materials such as metals, stones, or thick plastics.
Pure water jet cutting is a term used to describe a water jet cutting process in which abrasive particles are not added. In this case, it is the pressure and speed of the water itself that penetrates the material. Pure water jet cutting is ideal for soft materials such as fabric, rubber, or metal foil. Pure water jet cutting has become a staple in the food industry, where health and safety regulations limit many other cutting methods. Relying on water only, the pure water jet is used to cut through meats, fish, bread, vegetables, frozen foods, and even desserts. Some gourmet cake designers rely on the fine cuts and high precision of a water jet to produce culinary works of art.
