A water jet cutter, also known as a water jet or waterjet, 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 term abrasivejet refers specifically to the use of a mixture of water and abrasive to cut hard materials such as metal or granite, while the terms pure waterjet and water-only cutting refer to waterjet cutting without the use of added abrasives, often used for softer materials such as wood or rubber.
Waterjet cutting is often used during fabrication of machine parts. It is the preferred method when the materials being cut are sensitive to the high temperatures generated by other methods. Waterjet cutting is used in various industries, including mining and aerospace, for cutting, shaping, and reaming.
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. Additives in the form of suspended grit or other abrasives, such as garnet […]
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. In 1933, the Paper Patents Company in Wisconsin developed a paper metering, cutting, and reeling machine that used a diagonally […]
Waterjet cutting is an innovative and relatively new technology that allows for precise yet inexpensive cutting of a wide range of materials. The principle behind a waterjet is simple but nonetheless surprising. As the name implies, a jet of water is directed out of an orifice at about three times the speed of sound. The intense […]
Take ordinary tap water and pressurize it to 60,000/55,000 psi (4,000 bar) and force it through a very small hole. Mix the water with garnet abrasive and you have a very thin stream of water traveling very fast that will rapidly erode most materials. Some waterjets are “pure waterjets” and don’t add the garnet abrasive. […]
There is a difference between a pure waterjet nozzle and an abrasivejet nozzle. With the abrasivejet nozzle, an opening in the side of the nozzle allows for the introduction of the abrasive to the high-pressure water stream. The two are mixed in a mixing tube and then exit the nozzle. With a pure waterjet nozzle, there is […]
Bridge style waterjet cutting machine is one of the two traditional styles. It has two support points on each side, which makes the machine keep accurate and stable even after a long time process. It is suited to the material with fixed size or the material which is easy to load/unload. Bridge style cutting machine […]
China’s first fire engine equipped with a water jet cutter rolled off the assembly line on 04-28-2016. The fire truck is loaded with a super-hose with a patented nozzle, which can shoot an ultra-powerful jet of water capable of cutting metal or granite. Concrete pipes more than a dozen centimeters thick can be easily cut […]
Waterjet Safety With the development of ultra-high pressure waterjet technology, it is much safer to use waterjet than other equipment. But there will still be safety risks due to the improper use, operation, maintenance or other factors. Therefore, it is very important to learn all the instruction in this manual. Other than the rules in […]
Imagine if we use ordinary tap water and pressurize it to 60,000 psi and force it through a very small hole. Sometime we need to mix water with garnet abrasive. We will get a very thin stream of water with a high speed. This thin stream water will rapidly erode and cut most materials. That […]
The advantages of waterjet are the reason promoting the development of waterjet. Although there are a lot of advantages, they almost can come down to “versatility”. By using a waterjet, we can efficiently and cost-effectively create a wide range of parts by using widely different materials. The reason of waterjet can cut virtually any material […]
Shenyang All-Powerful Science & Technology Stock Co., LTD(APW), the largest waterjet industry in China, mainly engages in the research and development of ultra-high pressure waterjet cutting appliance, the production and sales of 3-5 axis waterjets. APW also provides high quality waterjet training and service. Custom waterjets at APW will help you rather than let you […]
Waterjet operating costs A ball park figure for a generic machine would be roughly $25 to $30 per hour plus whatever you pay your employees. The operating costs include the following: Abrasive An abrasivejet uses abrasive at a rate of between one-half and one pound per minute (0.2 and 0.5 kg/min). Over the course of […]
Although every waterjet model is different, there are certain standard features that will be present in all waterjets in one form or another. Controller The controller is the “brains” of the waterjet: it turns the high-pressure water pump on and off, moves the nozzle head and controls the abrasive flow. Most modern waterjets use a […]
Q: What cause the white light blink 3 time? A: The PLC get the signal from the sensor what the water pressure is too low. There are two reasons which may cause this. 1. The water pressure is low. 2. The sensor send the wrong signal. For the first one, we just need to make […]
Modern equipment is easier to maintain than even just a few years ago, and also requires much less maintenance than in years past. Much progress has been made in this area, but no machine is maintenance free yet. The factors that affect how often maintenance is required include: How the equipment is run The harder […]
Recycling systems are available. However, because waterjet systems use a small amount of water it is not economically viable for most users. waterjet http://waterjetapw.com http://waterjetapw.com
It is clean water. Most of our customers use softened tap water. Intensifier pumps should be supplied with filter cartridges that clean the water down to 0.5 micron. De-ionized or reverse osmosis systems are generally not recommended. These types of systems can make the water too clean, which makes the water aggressive and harmful to […]
Neither water nor garnet are toxic or hazardous in any way. Water, when properly filtered for turbidity, can be flush down to the drainage systems. The garnet waste can usually be dumped in a standard landfill. waterjet http://waterjetapw.com http://waterjetapw.com
Noise from the waterjet is dependent upon the distance the supersonic jet is exposed to the open air. If you are cutting underwater, the noise level will be under 75 dB. If you are cutting above water, and especially if there is a large distance between the mixing tube and the work piece, the noise […]
