Waterjet cutting technology once again there is a new breakthrough, the laser applied to the waterjet cutting process, using water jet and laser mixing and cutting materials to obtain higher cutting quality. Compared with traditional cutting technology has the advantages:
1, Lower heat
Many people used laser cutting all know, laser cutting may result in very high quantity of heat, but this problem will not occur in conjunction with water jet this cold cutting device, in the waterjet cutting process, the cooling aspect play the absolute role.
2, High flatness
In the metal cutting process, the water jet can be easily separated the dissolving liquid produced after the metal dissolution, without causing the dissolving liquid solidification again and burr generated, greatly improve the flatness of the cutting.
3, Parallel side walls
During the cutting process, the workpiece is fixed in a CNC worktable, in the waterjet-guided laser beam toward one direction to move. Laser head move along with the vertical direction, only in order to comply with a variety of working interval with different nozzles under different water pressure, only the necessary to change the interval between the workpiece and worktable. It will not change during the cutting process.

Alternative use of waterjet cutting in life
Using water jet cleaning equipment stains, since waterjet has small cutting force area, high pressure, free of impurities and other characteristics, so the use of CNC equipment fixed the waterjet nozzle to the object plane, use the impact of water jet to remove some equipment hard attachments is also very effective, such as the use of water jet to clear ceramic coating, chemical pipeline fouling and so on.
The use of waterjet cutting all kinds of non-metallic materials such as paper, diapers, glass, fiber, sponges, etc.. Common water after the turbocharger pressurized, generate the 200MPa or less low pressure water jet, acting on an area less than 0.1mm, can be up to about 915 meters per second, can cut a large number of soft materials at one time.
Use water jet for patient to perform surgery, and now many of the world's medical researchers have successfully tested the surgeries using a water jet removed the liver, kidney and other organs. Although all of the medical equipment will be disinfected before use, but there is still the risk of surgical infections, and if used the pure water after rigorous disinfection to form a water jet for the surgery, then the risk of surgical infection can be greatly reduced.
Further water jet can also be used to dismantle the bomb, processed foods and so on usage, tools are dead but people are alive, take advantage of all the characteristics of waterjet to develop new uses for the waterjet cutting, may allow people to get the unexpected reward in the production and processing.

Abrasive Waterjet Cutting Tips
Waterjet cutting machine summed up the abrasive waterjet cutting techniques in the process of long time use.
1, Smaller abrasive particles (120 mesh abrasive or smaller) of the cutting speed is slower, but surface is smoother (compared with the 60 mesh and 80 mesh abrasive);
2, If you need to regularly punch a hole for composites, glass and stone, ensure that the system can use the controller to reduce or increase the water pressure. At the same time to check the vacuum assist device or other technologies to enhance these brittle material or laminated material perforation chance of success;
3, Compared with the general porous flow controller, specially designed for process control systems are generally more efficient and easier to use;
4, Typically inject the tap water into waterjet system, before the water is injected into the booster, usually we will filter out impurities in the water through the water filtration system, 90% of waterjet and abrasive waterjet users only require soften the water. Water filters will greatly extend the life of the water outlet, but also improve the life of the turbocharger wearing parts;
5, Underwater cutting will reduce the possibility of abrasive waterjet cutting top surface frost or "fogging". Underwater cutting also greatly reduces jet noise and confusion in the workplace. The only defect is the operator during the cutting process is not clear to see the jet, we can consider electronic performance monitoring devices. The monitoring device is able to detect deviations from optimum cutting performance, and can shut down the system before the component is damaged.

To ensure the successful completion of waterjet cutting, we must carry out inspection work
When we using the waterjet cutting, due to the maintenance of the cutting head and delivery systems can not be guaranteed, it may cause more serious consequences. So when we conduct machining, to regularly check and maintain water jet cutting machine system to ensure its best optimal operating condition is conducive to the production. Specifically how to do it? Take the following steps.
First of all often open water at low pressure, to observe the gem nozzle flow situation. Normally, the water flow should be symmetrical, according to different types of nozzles, the width of the discharge water flow is not the same. General ruby and sapphire nozzle flow slightly wider, diamond nozzle flow is relatively narrow, and more coherent. If the water flow beginning wider, it means the nozzle is damaged, need to be replaced a new one, because if do not timely replacement of damaged nozzle, then it is likely to cause damage to the inside of the cutting head.
The second is to periodically check the cutting head whether has wear and tear phenomenon, sometimes some signs of damage caused by a number of factors that we are not easy to find, so be careful viewing. For example, after the sand tube accidental contact with the fixture, it will damage the nozzle nut of mixing tube to maintain the alignment and the internal parts.
Finally, sand delivery system consumable parts to regular inspection and replacement, such as pipes and fittings. To make sure any part of the sand transport system under the bottom of micro hopper is not exposed to the air. Specific operation of the first to disconnect the sand transfer line from the joint of micro hopper bottom, and then open the jet and the thumb stick in the end of the sand transfer line. Feel whether the sufficient amount of vacuum exists, because if the vacuum is insufficient, there may be cutting head entrance was blocked or sand delivery pipeline cracks, it should be resolved as soon as possible.
Through the layers of strict inspections to ensure the waterjet cutting machine processing smoothly, ensure the equipment parts in good condition, extending its service life.

High pressure water jet cutting to pay attention to what matters?
The main safety technical problems of high-pressure water jet cutting is to prevent high-pressure water jet and splashing water droplets impact, noise and electric shock.
1, Noise and prevention
When the high-pressure water jet machining, water jet flow rate of up to 100 ~ 600m/s, which will produce a lot of noise in the air.
2, Hazards and prevention of high-pressure water jet on the human body
High pressure water jet has great impact, direct injection into the human body will cause great harm. Even if the water jet is used for flushing or stripping process, about 25MPa pressure water jet can penetrate the human body; and the water pressure used for cutting up to 196 ~ 294MPa, such a high-pressure water jets can easily cut off human bone. In addition, if the recoil scattering drops of water injected into the eye, but also make eye damage. Therefore, we must prevent high-pressure water jet sprayed onto the body, you can take the following safety measures:
1, The operator should wear protective glasses at least, it is best to wear a protective mask.
2, To check or replace the cutting nozzle, the pressure of the high-pressure water must be released to the safety level, otherwise the operation can not be performed, in order to avoid accidents.
3, In the surrounding area of high pressure water jet cutting should be set up isolation screen to prevent in the process of human suffering water jet ejected and scattering drops shock effect.

Today the technology development of waterjet cutting machines
On the development of technology today, CNC waterjet cutting technology in the country has been very mature, CNC waterjet cutting machine technology in recent increase gradually, the understanding and application of waterjet cutting machine is also gradually deepening, we all know some other cutting easily produce large metal dust, smelly gas, glare, some cutting incidental questions for customers have a headache, in order to solve this problem, the advantages of waterjet cutting machine is manifested.
For example, waterjet cutting machine in some aspects is better than laser:
1, No limit of cutting thickness
2, Maintenance is not so professional as laser equipment and low degree of difficulty
3, Like brass, aluminum and other reflective materials can be cut
4, Can be easy to install more cutting head to increase production capacity
5, Without input energy, so it will not burn or produce thermal effects
6, You can have a complete set of waterjet cutting equipment for 1/2 to 1/3 of the price of a laser equipment.
7, When you change the cutting materials, you only need to change is the cutting; without have to change the gas, focus or other objects
Waterjet cutting machine working principle is that the water can remove dust, there is a lifting of the cutting platform for work. Due to the water factors will affect the cutting speed, cutting ability, surface finish so the operation still has certain requirements, cutting the same thickness of the steel plate, the energy consumption is lower than other cutting methods, manufacturing costs are relatively low.
In addition, waterjet cutting must be equipped with anti-collision devices or water pressure automatic adjustment device, when water jet cutting, due to the cutting water impact of material surface, the eye in short time is very difficult to determine the position of the cutting nozzle and the height of the distance from the cutting material, in the cutting process, the distortional steel plate if changes might collide with the nozzle, causing breakage or damage to the waterjet nozzle, when cutting, cutting head from the plate to a height of 3-5mm. The most obvious and biggest waterjet cutting features are: the use of wide-body enhancement of beam box structure, beautiful appearance. End frame with low center of gravity structure, symmetrical structure, good stability, ensure the overall rigidity strength and good dynamic equilibrium.

Ultra-high pressure waterjet cutting cold cutting technology leader
Waterjet cutting equipment is based on the ultra high-pressure water jet application of cold cutting technology. Compare with thermal cutting (such as flame, plasma, laser, etc.), the "water jet" can cut almost all materials from soft to hard, especially in the more than 20 mm thickness of metal, carbon fiber, titanium, aluminum, honeycomb structure and complex material molding processing, it has become an internationally recognized the best processing method. Waterjet cutting machine has been widely used in processing steel, copper and aluminum materials, glass, ceramics, carbide, plastics, synthetic fibers, cloth, paper, composite materials and others, and can be directly made structure parts or welded components, thus waterjet cutting system has become a new manufacturing equipment in the aerospace, military industry, rail transportation, shipbuilding, automobiles, engineering machinery, light industry, chemical industry, energy, construction and other industries.
CNC waterjet cutting machine consists of five major components: UHP generator, CNC machine tools, automatic abrasive delivery system, CNC system, integral cutting head. The simplest waterjet cutting machine has two CNC axes, controlled by CNC control X-Y do CNC movement, and can achieve CAD / CAM direct conversion, truly free keyboard input, no map processing, as long as the CAD to draw any complex curves, can be directly cut to shape.
Under normal circumstances, be able to make use of laser, plasma, flame cutting, sawing, milling and other processing methods basically meet processing requirements, is unfavorable use waterjet cutting, after all, waterjet cutting operation cost is higher, the nozzle, guide sleeve, high pressure seals are imported supplies, more expensive. But when you can feel the laser and plasma cutting thickness is too thin, the burr is too big, the heat affected zone is not good, you can consider using water jet cutting.
