The main cutting types of water jet cutting

Water jet cutters usually have two main types of cutting ways.

1. Pure water jet cutting

??With pure water, both soft and stronger, tough materials can be processed. In this process, the individual parts are separated by pure, filtered water. Since no dust or chips are generated or toxic gases are released, this variant of water jet cutting is environmentally friendly. After completion of the cutting process, the water can continue to be used and finally fed into the water cycle. The diameter of the water jet is relatively small, which prevents the formation of drops. It can be less than 0.1 mm. Especially with materials of only a small thickness, optimum, precisely fitting cutting results can be achieved.?Pure water jet cutters can achieve a maximum added value of 90,000 PSI / 6,200 bar. Due to its versatility and ease of operation, waterjet technology is one of the fastest-growing major machine tool processes in the world. As approved to create a bacteria-free hygienic cutting process method, the biggest advantage of waterjet cutting is the use of pure water for food Cutting. If the pressure of 4000 bar is built up during the cutting process, it is possible to accurately separate textiles up to a thickness of 30 mm.

2. Abrasive water jet cutting

??An abrasive water jet can be generated from a pure water jet. Three additional components are added to the cutting head:

????Focusing nozzle

????Mixing chamber

????Abrasive

??The addition of an abrasive agent is also necessary. First, the pure water nozzle ensures that highly compressed water is formed into a jet. At a speed of 1000 m/s, this jet shoots through the abrasive mixing chamber, creating a vacuum in the cutting head. Through a minimal opening in the cutting head, the actual cutting or abrasive agent can now be sucked into the mixing chamber. There it mixes with the water jet and exits, focused by the nozzle, for cutting. On average, this jet is 0.2 mm larger than pure water jet cutting. Garnet sand or olive sand is often used as an abrasive. The harder the abrasive used, the higher the cutting capacity. The abrasive water jet cutting can be used to cut kinds of metals, stones, glasses, and composite materials.??
