Abrasive water jets (like, for example, our TechMoon CNC machines) are state-of-the-art devices that can cut anything from stone, wood and glass to stainless steel. As high-tech as these amazing tools are, they make use of three relatively simple principles to operate.
Principle 1: Controlled water pressure
Abrasive water jet machines create extreme water pressure through the principle of forcing a large amount of water through a small hole. This concentrates a large amount of energy into a small area, which is then used to cut through various materials. The water is pressurized between 20,000 and 60,000 pounds per square inch (psi). The tiny hole the water comes out of on the abrasive water jet machine is known as the jewel or the orifice.
Principle 2: Abrasive cutting
Abrasive material such as garnet powder is added to the water stream as it leaves the jewel of the machine. This creates the ability to cut through hard surfaces, such as metal, glass and stone, than water alone. The water mixed with the abrasive erodes the material placed beneath it, particularly if the stream is moving. The speed of the movement is based upon factors such as the material being cut, its thickness, the type of abrasive and the water pressure in the machine.
Principle 3: Computer-assisted technology
Abrasive water jet machines use computer programs to control the cutting mechanisms. It is possible to put extremely intricate designs into the computer programs to achieve effects not possible with other kinds of cutting machines. The computer is also capable of making adjustments during the cutting process should problems arise from issues organic to the material being cut (for example, striations).

These are great tips, thank you for sharing. I have wanted to do some water cutting but I have heard that it can be very tricky. I have a few friends who have said that they have tried it and have been unsuccessful with their attempts. I think that I will contact a professional and have him do the cutting for me.
