Instructions of water jet cutting machine
Ultra-high pressure waterjet is to use intensifier pump to pressurize normal tap water to 100-300Mpa in a split second. Then convert water pressure to dynamic energy through diamond orifice mount assembly. This creates a very high velocity beam of waterjet to generate high speed friction to make cutting. Abrasive jets use the beam of water exiting the orifice to accelerate abrasive particles to speed fast enough to cut through various materials.

Water jet cutting uses a computer controlled machine capable of cutting any sheet or plate material. The abrasive water jet cutting process uses an exceptionally high, 87,000 psi, jet of water which is mixed with garnet as an abrasive to form a fluid cutting tool. The pressurised mixture is forced through a tungsten carbide tube with an orifice of 0.75mm diameter. Within the Mohs scale of mineral hardness, the abrasive has a rating of 8 where talc is 1 and diamond is 10. The resultant stream can cut detailed parts in materials from foam and plastics through to metals, carbon fibre, ceramics and even armour plate. It can best be described as accelerated erosion.
