Cutting with a water jet is a method of engineering for cutting objects using the energy from high speed, high density, ultra-high pressure water. The water is pressurized to a maximum 392 MPa (approximately 4,000 atmospheres) and projected from a small-bore nozzle (Φ0.1 mm).
Water that has been pressurized by an ultrahigh-pressure pump reaches a speed approximately three times the speed of sound, producing a water jet with destructive force.
Its applications are widespread, with some of its more familiar uses including cutting roof materials, dashboards and bumpers for automobiles. Cutting and demolition of concrete structures. It is also used in cutting aircraft fuselages that use new materials.
Features
No effects from heat
Cutting with a water jet is a non-contact form of processing. No drills or other tools touch the object, so no heat is produced, and there is absolutely no alteration to the object or changes in color.
No limit to the objects that can be targeted
Because cutting is performed with an extremely small volume of ultrahigh-pressure water, there is very little water on the cutting surface. As with laser cutting, there are no limits to target objects.
Facilitates cutting with shapes
Cutting and cutting out of any shape, from any point.Cutting is possible for three-dimensional bodies, as well as two-dimensional shapes.
Environmentally friendly
No dust is produced, so there is no impact on workers or the environment.
In addition, processing can be performed with water and sand (abrasive materials) only, so it is environmentally friendly.
