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.

What similarities and differences between pure waterjet cutting and abrasive waterjet cutting?

High pressure waterjet cutting technology with its easy operation, low cost cutting, high precision cutting, a wide range of cutting, etc. in a variety of cutting techniques occupying the top spot, is widely acclaimed cutting tool by manufacturer. Waterjet sand tube is important waterjet cutting machine parts, is pure waterjet and abrasive waterjet cutting obvious difference lies, and let these two similar cutting methods produce similarities and differences.

Pure waterjet cutting

Pure waterjet cutting is more traditional and original way of water cutter, its role in cutting disposable diapers, paper towels, fine jewelry, and other areas is very extensive.

There are a lot of people might be wondering, how can water cutter cutting dry diapers and wipes? This is because, when the high-speed water jet cutting the speed of the water is quite quickly, the water vapor generated in the cutting process ia less than we touch on material produced.

Flow generated during waterjet cutting is very thin, the diameter is generally in the 0.10mm, with the high-speed flow, cutting effect can produce extremely high accuracy. When pure waterjet cutting the material is less losses, saves the production costs. And the waterjet cutting speed is very fast, thus increasing the cutting speed, thereby increasing the cutting efficiency.

Internal pure waterjet cutting machine without sand tube, mainly used for cutting softer texture, lighter material, the use of the machine can be fixed, and can maintain 24-hour operation.

Abrasive waterjet cutting

Abrasive waterjet cutting has one more waterjet sand tube part than the pure waterjet cutting, therefore, it is compared with the pure waterjet cutting, when cutting the water jet cutting make the sand flow speed in growth, will not cause erosion problems of materials.

In addition, the energy released by abrasive waterjet is thousands of times of pure waterjet, so that the abrasive waterjet is generally used for cutting metal, ceramics, stone, composite materials and other hard texture of the object, with good cutting effect.

The use of abrasive waterjet cutting is very extensive, it does not produce mechanical stress at work, fine material incision, cutting surface smooth, can be used for cutting layered materials, equipment replacement and installation is also more convenient.

Similarities with pure waterjet cutting is neither hot cutting, cutting precision is higher, the material losses are very small, the operation is relatively simple, economical and practical.

As can be seen that the waterjet cutting with sand tube has a wider range of cutter scope than ordinary pure waterjet cutting, in addition, both with ease of use, cost savings, high cutting precision similarities.
