How can water cut through a hard material

How can water cut through a hard material

Water may appear so soft and delicate, but it is one of the strongest forces of nature. With a certain amount of pressure, along with unique tool, water can cut through almost anything with superior smoothness and precision. Machine shops, building companies, and other business use pressurized water to cut metal, stone, granite, marble, wood, plastic, stainless steel, and other materials. True enough that when you get water at a certain force or pressure, it can cut through almost anything. This technology is called waterjet cut. A waterjet cutting machine is used in many shops and factories for manufacturing, construction, and designing.

Waterjets are first used in the mining industry back in 1852 in California. However, they used low-pressure waterjets. High-pressure waterjets were not used for mining until 1960s. In the 1900s, people were already using steam and hot waterjets for cleaning. Waterjets as well as abrasivejets are used for cutting in 1980s.

 

Cutting Metal

Using water to cut through metal utilizes a very narrow nozzle with a jewel, usually sapphire. The pressurized stream of water passes through this tiny, jeweled nozzle at an ultra-high pressure. Many types of cutting methods and process are available on the market and each has its own advantages and disadvantages. Among these cutting methods, waterjet has the most benefits. Because waterjet uses only the power of water, it does not overheat and it never gets dull like other metal cutters.

Back in the day, one can only cut one piece of metal at a time using a saw or other metal cutting devices. This traditional cutting method is expensive, labor-intensive, and time-consuming. Today, we now have waterjet cutting technology that is controlled by computer, which is able to cut many different materials, both soft and hard. Waterjet cutting can be pure waterjet or abrasive waterjet cutting. The two types are basically the same, except for the fact that the abrasive waterjet uses an abrasive to speed up the cutting process.

 

Waterjet Cut

A waterjet is capable of cutting a pile of different materials that is up to four inches of thickness. This cutting method doesn’t use heat, it is odorless and dust-free. Waterjet can slice a material as thin as five thousandths of an inch. Furthermore, waterjet is a single cutting process, which is it extremely precise and smooth, saving production costs such as materials, labor and machinery.

Cutting is performed with the material being cut a little bit submerged in water, reducing noise and splash. With a pressure of the water as anywhere from 20,000 to 55,000 psi or pounds per square inch, and being forced through a tiny, jeweled orifice with a size of 0.010″ to 0.015″ in diameter, you could expect that water can cut through hard materials.
