A water jet is an industrial tool capable of cutting a wide variety of materials using a very high-pressure jet of water, or a mixture of water and an abrasive substance. The water jet is commonly connected to a high pressure water pump where the water is then ejected from the nozzle, cutting through the material by spraying it with the jet of high-speed water. It has developed enough to be applied without post-processing for the cutting and processing of almost all materials.
Abrasive water jet cutting is a technology that has been developed for the first time in Korea by Ilshin Autoclave. In the case of Dry water jet cutting, an abrasive substance is mixed into the jet stream by being sprayed by a nozzle and passing through the Mixing Chamber, however, Abrasive water jet cutting is a method of ejecting the mixture of water and an abrasive substance that is mixed together in advance. Abrasive water jet has many benefits such as high cutting efficiency in low pressure, cutting products without air bubbles, and recycling used abrasive substance.

Principle of Water Jet Cutting
* Abrasive Water Jet (Mixing water and an abrasive substance in vessel)
• Injection / spray of an abrasive substance in
a wet condition
• Recycling used abrasive substance
(More than 95% recovery)
• High efficiency at low pressure
(50 ~ 120MPa)
* Dry Water Jet(Mixing an abrasive substance in Mixing Chamber)
• Injection / spray of an abrasive substance in
a dry condition
• Used abrasive material is discarded
• Highly effective at high pressure
(300 ~ 600MPa)
Advantages of Abrasive Water Jet
• Cost-reducing due to recycling of an abrasive substance
• High quality of the cut surface by using wet abrasive substance
• Prevent burr and thermal deformation
• Processing complex shape such as a curve.
• Applying for a variety of materials such as metal, plastic, and glass.
• High cutting effect at low pressure
• High productivity due to applying multiple heads and stacked cutting
Applications
• Cutting : Metal, ceramic, glass, plastic, and semiconductor parts
• Cleaning : Burr, chemicals, dust and foreign matter
