An abrasivejet uses a mixture of water and abrasive to more effectively cut through materials. A pure waterjet (one without abrasives) is effectively only for very soft materials, such as rubber or food products. Adding abrasive, however, greatly enhances the cutting capability and the abrasive waterjet can cut through steel.

Pressure matters in abrasive waterjet cutting

How pressure affects cutting speed, kerf width, and abrasive use Abrasive waterjet pump technology continues to evolve toward higher pressures. Within the pump’s design limits, the higher the pressure, the faster the abrasive moves, and the faster you can cut. Over the past three decades, abrasive waterjet machines have evolved from a relatively crude cutting […]

Water and Metal

When I used to picture metal cutting, I would always picture incredibly heavy, large machining pieces. Basically the only way I could picture cutting metal was by using metal. However, I later learned that there are other ways to achieve metal cutting, and it is a very interesting process. One option that is becoming increasingly […]

Waterjet Machining and Peening of Metals | Part 4 Summary and Conclusions

Summary and Conclusions An experimental study was conducted to determine the influence of material properties on the surface integrity and texture in WJ and AWJ machining of metals. Based on experiment, it can be concluded that waterjet peening with high-pressure jet is capable of inducing surface/subsurface work hardening. The resulting compressive residual stresses were comparable […]

Waterjet Machining and Peening of Metals | Part 3 Results and Discussion

Waterjet Peening. Figure 2 shows the typical erosion surface photomicrographs of water-peened specimens with different jet conditions. The erosion region resulting from the jet obviously varied with respect to the standoff distance ~SOD!, with it being narrowest and deepest at the minimum SOD. Removal characteristics within the impact zone were found to be predominantly dependent […]

Effects of process parameters on surface roughness in abrasive waterjet cutting of aluminium

Effects of process parameters on surface roughness in abrasive waterjet cutting of aluminium M. CHITHIRAI PON SELVAN, N. MOHANA SUNDARA RAJU, H. K. SACHIDANANDA Abstract Abrasive waterjet cutting is a novel machining process capable of processing wide range of hard-to-cut materials. Surface roughness of machined parts is one of the major machining characteristics that play an important role in determining […]

Advantages of Abrasive Water Jet

Advantages of AWJ In the early 1980s, AWJ machining was considered as an impractical application. Today, state-of-the art abrasive jet technology has grown into a full-scale production process with precise, consistent results. There is a similarity between wire EDM and AWJ machining. Both cut complex contours with a kerf. The diameter of the jet is […]

Abrasive Water Jet Article

Abrasive Water Jet Abstract: with the improvements of industry techniques and the Application of proper material of proper material, abrasive waterjet is widely used in many industry areas. Several case histories will be presented in this paper to illustrated application and performance of abrasive jetting. And the development of abrasive jet drilling is also mainly […]

Abrasive Waterjet

While cutting with water is possible for soft materials, the addition of an abrasive turned the waterjet into a modern machining tool for all materials. This began in 1935 when the idea of adding an abrasive to the water stream was developed by Elmo Smith for the liquid abrasive blasting. Smith’s design was further refined by […]

Waterjet vs. abrasivejet nozzles

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 […]

How to dispose the used garnet abrasive?

Water jet Garnet is a non-toxic natural substance that can be recycled for recycle. Usually, the used water jet garnet can be disposed to landfills. Some garnet suppliers offer recycle garnet services. Disposing of waterjet abrasive—the right way Shop owners who cut with waterjet machines should keep abreast oflocal waste and disposal regulations. For many […]

What is the difference between water-only water jet and abrasive water jet?

Commonly, “Water jet”can be used as both “water-only” water jet and “abrasive” water jet cutting. Water-only water jets cut with ultra-high pressure water alone. Abrasive water jets cut with an abrasive material (usually garnet) which added to the water stream. Water-only water jets are used to cut through softer materials such as rubber and foam. Abrasive […]
