High-pressure water with or without abrasives cuts a wide variety of materials without the generation of polluting heat. There are almost no limits to water-jet cutting in terms of cutting material and applications. The process is essentially the same as water erosion found in nature but accelerated and concentrated by orders of magnitude. The actual cutting is often done under water to reduce splash and noise. The water is forced through a 0.010" to 0.015" in diameter orifice (hole) in a jewel. It is a very efficient and precise cold cutting process using water jet technology. Note that for a water-only nozzle that is designed for cutting soft materials, the mixing chamber and tube are eliminated and the coherent jet of water alone cuts the material. While there have been recent technological advances, the basics of how a water jet cutting machine work have remained the same for decades. Water Jet Cutting Machines: How Do They Work? There are few materials that can't be effectively cut with a waterjet cutter; one of these is tempered glass which shatters when cut, regardless of the cutting technology used.

There are two types of waterjet: pure and abrasive. The water pressure is typically between 20,000 and 55,000 pounds per square inch (PSI).

In order for the abrasive waterjet nozzle to cut efficiently and to increase component life, it is critical that the jewel orifice is carefully aligned in the nozzle body. Waterjet cutting offers several advantages over other machining technologies:The cutter is commonly connected to a high-pressure water pump (a local water main does not supply sufficient pressure) where the water is then ejected out of the nozzle, cutting through the material by bombarding it with the stream of high-speed water. A waterjet cutter is a tool capable of slicing into metal or other materials using a jet of water at high velocity and pressure, or a mixture of water and an abrasive substance. This pushes a flow of filtered water that is intensified by 20 times to 4,218 kilograms per square centimetre (60,000 pounds per square inch).Pure waterjets are used to cut card, nappies and soft materials. Many types of water jets exist today, including plain water jets, abrasive water jets, percussive water jets, cavitation jets and hybrid jets.All rights reserved © 2020 Big Blue Saw. In 1933, the Paper Patents Company in Wisconsin developed a paper metering, cutting, and reeling machine that used a diagonally moving waterjet nozzle to cut a horizontally moving sheet of continuous paper.
It is often used during fabrication or manufacture of parts for machinery and other devices.

How does water-jet cutting work?

Please reload the CAPTCHA.Time limit is exhausted. Additives in the form of suspended grit or other abrasives, such as garnet and aluminum oxide, assist in this process.

Please reload the CAPTCHA. These early applications were at a low pressure and restricted to soft materials like paper. Most Abundant Metal In The Earth’s Crust – Aluminium Time limit is exhausted. How does a Water Jet Cutter Work The amazing tech that enables water to accurately cut both soft and hard materials. The velocity of the water from the jet, rather than the water pressure itself, erodes the microscopic grains of the material using this technique.Abrasive waterjets, on the other hand, incorporate a rough substance like sand that is accelerated by the water to erode the material, which can include metal, stone or ceramics.

While using high-pressure water for erosion dates back as far as the mid-1800s with hydraulic mining, it was not until the 1930s that narrow jets of water started to appear as an industrial cutting device.

Our customers use waterjet cutting to make The most important benefit of the waterjet cutter is its ability to cut material without interfering with the material's inherent structure as there is no "heat affected zone" or HAZ.

Faster feed rates are used to prevent the jet from cutting all the way through. Combined, these two technologies can cut virtually any material, any shape, at any thickness.

This allows metals to be cut without harming or changing their intrinsic properties.In the 1950s, forestry engineer Dr. Norman Franz experimented with an early form of water jet cutter to cut lumber. Some Interesting Facts - Random interesting facts from the World

Water and garnet exit the cutting head at nearly four times the speed of sound, capable of cutting steel over one foot thick. Because the nature of the cutting stream can be easily modified, waterjets can be used to cut materials as diverse as polyethylene plastic and titanium. Today the water jet is unparallelled in many aspects of cutting and has changed the way many products are manufactured. Use of them does not imply any affiliation with or endorsement by them. The amazing tech that enables water to accurately cut both soft and hard materials.Waterjet cutting can be used to slice through most materials and is a process that does not give off hazardous vapours or waste.Intensifier or direct drive pumps get the water to the high pressure needed for cutting.
