Waterjet cutting device has its own unique advantages, so waterjet technology is recognized worldwide as the most common and the fastest growing technology. Compared to other cutting technologies, the waterjet does not produce toxic or harmful gases or liquids, and do not produce toxic or harmful substances or steam. After waterjet machining, in workpiece surface will not produce heat reaction zone or mechanical stress remains. Waterjet is indeed a universal, high capacity cold cutting technology. We come to you to talk about waterjet cutting machine advantages in cutting processing.
In order to reduce production costs, engineering and manufacturing departments are always looking for superior cutting method. Waterjet technology endowed with many unique features and advantages, can be very effective in reducing costs.
Waterjet divided into non-abrasive waterjet and abrasive waterjet two kinds
No abrasive waterjet
No abrasive waterjet is a way to use water directly cutting, no abrasive waterjet started to be commercially applied to cut corrugated cardboard. No abrasive waterjet be applied to cutting disposable diapers, tissue paper, and automotive interiors by a large number of users. When cutting the tissue paper or paper diapers, no abrasive waterjet operations generated a small amount of water vapor is much less than the steam caused by human contact or breathing. For general non-waterjet cutting process accidental downtime to the tissue paper or paper diapers producer caused a lot of economic losses. The water jet device can provide the above industrial applications throughout the day, the week, the year of the safe use.
Abrasive waterjet
No abrasive waterjet can be used cutting only some of the soft materials, but for steel, iron, stone and other hard materials, non-abrasive waterjet can not be cut or cutting speed extremely slow. If adding an appropriate amount of abrasive in water arrows can be used to cut almost all hard and soft materials.
Abrasive waterjet and non abrasive waterjet exist some differences, no abrasive waterjet use water jet etching material, and abrasive waterjet use sand jet accelerated by water jet, accelerated sand jet to etch the material, abrasive waterjet energy is thousands of times of no abrasive waterjet. Of course, no abrasive waterjet and abrasive waterjet have their respective applications areas. No abrasive waterjet can cut soft materials, abrasive waterjet can cut hard materials.

Waterjet and waterjet cutting technology detailed analysis
Waterjet because of the need to use a powerful pressure, so water jet diameter is very small, so as to produce strong pressure. Water jet is through ultra high pressure generator pressure water to 300MPa or more, spray through a fine nozzle made of advanced carbide, sapphire, diamond or others, its speed is several times of the sound speed, this high pressure water flow with a strong cutting ability, but also by adding sand and other abrasives which can make the cutting ability of several fold enhancement.
High-pressure water jet can cut almost all materials quickly: glass, rubber, fibers, fabrics, steel, stone, plastic, titanium, chromium and other nonferrous metals, composite materials, stainless steel, reinforced concrete, colloids, soil. So to speak, in addition to the diamond and tempered glass (friable), there is no material that the high-pressure water jet cutting machine can not cut. And it can be safely cutting inflammable and explosive materials, as applied to the abandoned shells, bombs dismantled cutting.
Waterjet cutting small kerf (about 1-2MM), high cutting accuracy (0.0002mm), can be free to cut a variety of complex graphics, waterjet cutting incision smooth, no burrs, no heat no annealing phenomenon, cutting surface flat, widely used in aircraft parts, precision mechanical gear, printers, Walkman gear, parts and so on.
Waterjet has relatively high requirement for water, pipes, nozzle. Such as pipes, water jet is the use of high pressure tool after the water pressure and spray out, must have a very high pressure to cut the hard cutting materials, so the pipe must be able to withstand extremely high pressure, the pressure is much greater than 700 MPa, because thin steel plate (the material being cut) itself can withstand the pressure of 700MPa. Secondly, waterjet used water completely free of impurities is wrong. Because the pressure is much greater than 700MPa, for the pipeline and other sealing devices, no matter how good the sealing performance, pure water will always make them wear and leakage. To solve this problem, the water jet used water should add 5% soluble emulsified oil, improve the sealing effect. For the high-pressure pump, but also add some oil to improve the sealing performance.

Present situation of waterjet cutting technology
Parts cutting technology can be divided into plasma cutting, flame cutting, water jet cutting, wire EDM, laser cutting, mechanical cutting, etc., in which the waterjet cutting technology is relatively complex. What about our waterjet cutting technology development? The waterjet cutting machine manufacturers talk about this issue with you.
In recent years, with the "ultra-high pressure CNC waterjet cutting machine" (also known as "water jet") mature and expand the scope of application, it gradually entered a growth period, which also partly due to the rapid development of China's economy. Relying on more precise machine tools platform and high-power high-pressure system, waterjet cutting application range can be extended to metal processing and industrial manufacturing, processing more and more sophisticated products, but not only limited to glass, ceramics, stone and other materials processing.

Application of ultra high pressure cutting technology
Ultra-high pressure waterjet cutting technology is presented first by the Soviets in the hands of the Americans to be relatively perfect a jet technology. Abroad from the late 1970s, waterjet cutting technology applications, after all these years of continuous research and improvement, application, has been developed to a high level of application.
In terms of pure waterjet cutting, waterjet cutting technology with robot technology is widely used in automotive, aerospace, clothing, rubber, ballistic material and other industries. Such as water jet and automatic robot arm combination to complete the three-dimensional of cutting. This automated system can be used in automotive interior parts and aerospace components and other cutting. Difficult to process composite materials using traditional processing methods, waterjet cutting is at ease, such as the arsenal want to processing Kevlar material imported from Holland which is used for tanks, armored vehicles, bulletproof vests, bulletproof car bulletproof layer, within the overall context of the soldiers can not solve the problem cropped materials, waterjet cutting quickly resolved.
In the field of abrasive waterjet, machining abrasive cutting, the application is more extensive, have been involved in the stone, glass, metal, composites, building ceramics, bulletproof glass, and other industries. Such as iron ore used the ore conveying pipes, because the tube is coated with a layer of composite ceramic to enhance wear resistance, but the tube and therefore becomes difficult to process, by machining is not tool hardness not enough, it is the result of too much vibration and damage machining plating ceramic layer, to solve this problem of waterjet is the best choice for cutting tools.
1996 Domestic waterjet officially on the market immediately attention by all sectors of society, and quickly widely used in building ceramics and stone industry. Used in deep processing of construction ceramics and stone, get great economic benefits. It has developed into a mature processing means.
Compared with traditional cutting methods, waterjet cutting mainly has 7 advantages:
1, Cold cutting means - to avoid the effects of thermal distortion, material hardening and the stress of the material.
2, Without or a small, simple clamping device can be OK.
3, Without material limitation, it can cut almost any material (toughened glass, tungsten carbide).
4, The complicated pattern, thick, difficult to cut, fragile and sensitive to heat the materials, most suitable for waterjet cutting.
5, With a narrow kerf, cut smooth, no burrs, no need secondary processing cutting surface, save material, reduce costs (titanium alloy).
6, For precise contour cutting.
7, No sparks flying etc. when cutting. And there is no dust and harmful gas pollution environment during the cutting process, so high pressure water jet cutting technology also has environmental protection significance.

The use of waterjet sand tubes can effectively reduce the cost and improve the efficiency
With industrial development, engineers have been trying to cut costs, we are committed to finding new advantages. Waterjet technology has many unique features and benefits. Understanding of the waterjet and the waterjet inside sand tubes this advanced technology, you can have the opportunity to take advantage of these advanced equipment to reduce costs and improve efficiency.
Waterjet cutting machine can greatly reduce costs, It is widely considered to be the most versatile, the fastest growing and processing technology. Waterjet use in the world has been very extensive, into the various fields. It is complementary to other techniques.
Waterjet sand tube cutting technology is very safe, green, without the use of toxic gas or liquid, it does not produce toxic substances or vapor in the course of work. At the same time after used waterjet cutting surface without leaving any remnants or does not produce mechanical deformation. Waterjet is a recognized truly versatile, while very efficient cold cutting technology.
Waterjet has been widely used in various cutting applications, more and more people are finding waterjets can do things that other technologies can not handle. In the cutting of stone and metal, fast drilling, cutting food, and even sterilization areas play a unique role.
Dr. Norman Franz is the father of the waterjet. He is the world's first ultra-high pressure water jet cutting tool research people. Higher than 1300 Pa are we seen as high-pressure, Dr. Franz wanted to invent a method for cutting trees. In 1950 he tried to suppress water flow with a heavy thing, allowing water to flow out from the hole to generate high pressure, high-pressure jet of water that can then be used to cut the branches. He later in-depth study of how to make more a continuous flow of water, but he wanted to build a more continuous high pressure is very difficult. Meanwhile, under the pressure of oppression, corruption of waterjet sand tubes and other parts is unusually fast.
Dr. Franz failed to produce a wood cutter can be widely used, but his ideas have influenced later generations, a lot of people realize that cutting the material with high-pressure water is feasible.
In 1979, Dr. Mohamed Hashish discovered the enormous power of high pressure water jet and future great value. He began to study in laboratory of increase waterjet cutting energy, thereby more efficiently cut metal and other high hardness materials. Due to the use of garnet sand this material as a waterjet tube sand, water jet played a great power, almost can cut any material. Thereafter, the water jet was first used to cut metal concrete and glass.
Currently, the waterjet has successfully commercialized, is widely used in various fields, even in aerospace science and technology, water jet also play a huge role. Like high-strength stainless steel, titanium and other materials, which cutting is very difficult, extremely high accuracy requirements, only waterjet cutting can easily complete accurately, and efficiency is very fast, but also environmental protection, does not produce harmful substances.
