What is Water Jet Cutting?

Principle of water jet machining

A “water jet” is a stream of water that has been pressurized to ultra-high pressure and ejected at ultra-high speed. “Water jet processing (water cut)” means using this ultra-high pressure and high speed water such as “cutting (cutting), drilling, grooving, peeling, deburring, hanging, drilling, shot peening, cleaning, stirring” Processing method or processing system that performs them.

Abrasive machining to process harder materials with high accuracy

A general water jet system in the industrial product manufacturing field filters tap water with a micron filter, pressurizes it to about 320 MPa with a dedicated high-pressure pump, and speeds Mach 2 through a hole (water nozzle) around φ0.1 to 0.3 mm. Generates a thin high-speed water flow of about 3

Abrasive material (abrasive grains) was mixed at the tip of the water flow around φ0.1-0.3mm and attached to the tip. Abrasive construction method that cuts with water flow from a nozzle (mixing nozzle) of about φ1mm It is called jet processing (commonly called water jet processing, processing with abrasive).

Hydro jet machining

For abrasive jet machining, a cutting method that does not include abrasives and cuts with a thin water flow of around φ0.1 to 0.3 mm. This is called hydro jet machining (commonly known as hydro machining or water-only machining).

• No or little thermal effect on the material due to processing
• No or no stress on the material due to processing, so no stress remains
• There is no modification or alteration of the material due to processing, and it does not damage the material function.

• Due to the above features, no toxic gases or new compounds are generated.
• The above features do not cause distortion in the material
• The above features make it easy to process soft materials, thin materials, and fragile materials.

• Hard and tough materials can be processed
• Various materials can be processed by the above features.
• The above features enable processing of composites and laminates

• Processing such as deburring and peeling is possible by adjusting the water flow.
• Since the water flow is tap water and the abrasive is natural stone, it is environmentally friendly
• Because it is processed with water and natural stone, oils, additives, cleaning agents, etc. are not used for processing and post-processing.

• Processing is possible with metal, plastic, glass and ceramics
• Capable of processing from soft materials such as sponges and gels to hard materials such as superalloys
• Capable of processing from 0.1mm thin film to 300mm thick metal and products

• Natural materials such as wood and stone can also be processed
• Can process multiple materials such as composites and laminates
• Cutting of household appliances and equipment modules is possible
