The ultimate guide to FAQs

abrasive waterjet cutter


What do you mean by abrasive waterjet cutting?

The high-pressured water flowing from the abrasive waterjet cutters combines with abrasives (like garnets) applied to the nozzle to cut materials of any thickness and type. You can define abrasive waterjet cutting as the supersonic erosion to spray out water at about 60000 PSI. However, it is easy to switch between abrasive waterjet and water-only cutting based on your needs.

There are several components included in the abrasive waterjet cutting systems. The most important ones of them are the PC-based controller, pump, cutting head nozzle, and cutting table.

You may use advanced control software to program the cutting path from the CAD drawing. In this way, you will find the best result from the cutting process.


What factors should you consider for abrasive waterjet cutting?

Abrasive waterjet cutters are user-friendly systems useful for different manufacturing projects. However, in some cases, manufacturers overlook important things while dealing with waterjet cutting systems. These relevant factors, include

  • Overspray and dust– The novice waterjet users do not know that without proper preparation, the overall operation will be messy. Overspray can drench the surrounding area of your waterjet system. Moreover, it is better to purchase high-quality waterjet cutters integrated with enclosures and fans.
  • Water temperature and quality- The quality of water may vary due to the presence of particulates. Materials present in the water have a chance of damaging the jewel in the nozzle. The nozzle body also has a concentrator. Furthermore, water temperature is another relevant factor. The seals used for the mechanism have a risk of damage for the application of warm water. RMWL filters its water and runs the water through chillers to maintain an ideal temperature—one that’s no higher than 45° F (7° C).
  • Operator training-Do not think that you can use other machining skills for waterjet cutting. Reliable waterjet manufacturers will train you on how to use the system.
  • Occasional cleaning of remnants and chips– Waterjet cutting systems do not turn out a high amount of debris and chips. You may not find this advantage in case of the milling process and other operations. But, it is still essential to remove the cutting remnants and leftovers from your machine. It will help you in operating the waterjet cutting system smoothly. Moreover, you can minimize the risk of equipment wear and tear due to this effort.

Other important factors for your waterjet cutting project are

  • The easy availability of water for the pump
  • A system to drain wastewater


Can I use waterjet cutters and abrasive jets for some secondary purposes?

Although cutting is the most important target of these machines, you can use the waterjet cutters for several other needs-

Sectioning- It is the process to cut patterns from sheets.

Deburring- Removal of sharp edges from a part

Web slitting- For web slitting, abrasive jet cutters include a winder, coil feeder, and rewinder.


What are the different types of abrasives used for waterjet cutting projects?

You can find abrasives of different types, including garnets, olivine, staurolite, copper slag, and crushed glass. However, you may notice differences in grades, sizes, and brands. Garnet is the most commonly used abrasive for water jet cutters. It minimizes silica content and stabilizes the cutting speed.


How do waterjet abrasive cutters differ from air abrasive jet cutters?

While using the abrasive water jet cutters, the abrasives work with the high-pressure water to cut through different materials. Garnet grains play a vital role in the cutting process.

On the contrary, the air is the propelling fluid for the air abrasive jet cutters. The most commonly used abrasive grains in this process are silicon carbide and aluminum oxide.


Can I use abrasive waterjet cutters for 3D cutting purposes?

Yes. You can apply 3D machining for the curved surfaces. Under high pressure, water (up to 4000 bar) passes through the nozzle. Then, you have to put abrasive agents with the vacuum created in the chamber. Combined with abrasives, high-pressure water can slice through the hardest workpiece.

However, you have to be careful while positioning the cutting head. You can make 3D cuts of different flat plates. But, our waterjet cutters also enables you to cut the curved surfaces. Thus, for your 3D cutting needs, you can rely on our systems.


For which materials can I use abrasive waterjet cutters?

Due to the use of abrasives, our waterjet cutters gain high efficiency in cutting different types of materials, like-

  • Stainless steel and steel
  • Aluminum
  • Tiles
  • Ceramic
  • Stone
  • Thick plastics
  • Carbon
  • Standard glass, bulletproof glass, and laminated glass (not tempered glass)


How will I select the right abrasives?

The choice of abrasives is one of the most important tasks for your waterjet cutting projects.  It will directly affect the way how your abrasives will work for your projects. You have to check out some attributes (like hardness) while selecting the abrasives for your waterjet cutting purposes.

Waterjet cutting systems have to balance component wear and cutting speed. You can choose soft abrasives to make your nozzle long-lasting. However, they can lower the cutting speed. On the contrary, although hard abrasives ensure a fast cutting process, they can erode your nozzles. It will lower the accuracy level of your cuts. Ultimately, you will find a risk of downtime. You need to replace nozzles several times. Check the hardness level of the garnet. On the Mohs Scale, it should range from 7 to 8. It will help you with faster cutting and maintenance of cutting tool life.


Should I check the density of the abrasives?

The best quality abrasives used for waterjet cutting projects contain heavy particles. These particles help in accelerating the velocity of the flow of water. It will also generate the highest level of cutting force.

Too much light waterjet abrasives do give a good punch. Similarly, too heavy abrasives will not accelerate the velocity. That is why there should be medium-level density with the specific gravity of about 4.0.


How much tough will be the waterjet abrasives?

Toughness of abrasives is one of the important factors affecting the performance of waterjet abrasive systems. Some abrasive materials easily get crumbled and reach the focusing tube. On the contrary, highly tough abrasives can make dull cuts. The quality abrasives ensure sharp and angular cutting edges.


What should be the shape of abrasive particles?

You can find abrasives in an array of shapes. It can range from needle-like crystals to perfect beads. The high-tech applications need synthetic abrasives. However, for your high-pressured water stream, you can use the spherical shaped abrasives. But, while choosing the abrasives, your focus must be on a perfect balance of cutting, wear, and acceleration.

With in-depth study and research works, waterjet professionals have found that you must decide on the abrasive shape based on the chosen materials. It is easy to cut sharp and angular grains that offer the superior finish.

To learn more about abrasives, you can consult our waterjet cutter manufacturers.


How do I identify the purity of the waterjet abrasives, like garnets?

The best garnets are properly mined and processed to ensure better outcomes.  These high-purity materials have undergone a refining process with high attention to every detail. This is how high-purity materials differ from the low-purity ones. However, high-purity abrasives can be slightly costlier. Still, to get superior cutting results, you can look for pure abrasives. In case of low-purity products, you can find a combination of other materials with garnets. They can affect your waterjet cutters’ cutting capabilities.


Should the abrasives for waterjet cutting be coarse or fine?

There must be consistency in the size of the abrasive particles. This factor is important to ensure that waterjet cutters perform at the optimal level. Oversized and coarse particles can risk your nozzle by causing clogging problems. They will interfere with the machining process and damage your workpiece. On the contrary, too much fine abrasives will collect in your cutter’s head. There will be an irregular feed  Operators will encounter problems due to inconsistent distribution of particles, as they need to control the abrasive feed rate for proper cutting speeds.


What does the cleanliness of abrasives denote?

Cleanliness is one of the attributes of waterjet abrasive. It indicates how much superfine particles are present in the abrasive. Those small particles stick to the bigger ones. The quality garnet abrasives manufacturers use a type of measurement, known as suspended solids. It will measure the cleanliness of the abrasives. Improperly processed abrasives turn out nuisance dust at the time of loading the hopper.


Will I get the best quality abrasive waterjet cutting head from your company?

With our premium-quality abrasive waterjet cutting head, you can process different types of hard materials. The cutting head comprises a number of parts, including orifice, pressure valve, nozzle (focusing tube), and mixing chamber. You can find different combinations in our cutting heads. They are easily adjustable based on your cutting conditions. We have designed the high-pressure waterjet valve using the best technology to prevent risks of other parts.

Moreover, our high-performance nozzles include multiple components intended for high reliability and user-friendliness.


How will I solve the water leakage problems of my waterjet cutters?

There may be several reasons behind the water leakage. However, most commonly, it is caused by the damaged waterjet seals in your pump. You have to find the source of water. It is highly important to solve the problem without any delay. Water leakage may damage your waterjet cutters’ components.

In case of the old seals, water will drip slowly. You have to buy new seals to replace the old ones. Hot water may come out of the hole of the waterjet’s output adapter. Loose fittings cause this problem, and you have to adjust them to solve it.

In some cases, the end cap turns out the cold water leaking issues. It indicates that you have to replace your O-rings present in the check valve.  When the end cap is the source of leaking hot water, you have to check your high-pressure seal.

In other scenarios, water starts leaking from the cylinder’s dynamic end. It denotes that there is some issue with the high-pressure seal.


How will I make the high-pressure water seals long-lasting?

In most cases, high-pressure water seals do not have a long lifespan. However, we have some tips to make those seals last longer.

You may use the pure water to ensure that there is no high level of impurities. While you think of adding the new seal, you have to remove the old one. There should be no debris at the time of replacing your old seals.

Before purchasing the new seal, you must ensure that it can deal with the minimum water volume and pressure volume.

You have to test the hydraulic cartridge regularly to prevent it from wearing away.


My intensifier pump of waterjet cutting system cannot develop hydraulic pressure. What will I do?

Check out these troubleshooting tips for your waterjet cutter.

Using the CNC waterjet software, you can identify the waterjet pressure. Moreover, you have to test the pressure control system while you deal with the machine manually. Make sure that everything is in a proper condition.

Inspect the hydraulic relief valve’s temperature. A rise in the temperature indicates that the valve has started opening. Separate the pressure control circuit from the intensifier pump compensator. You will be able to find how it increases the pump pressure.


The water pressure is very low. How will I solve the issue?

ome waterjet cutter users have claimed that their system is not generating high pressure. While using the cutting head, they find the decrease in the water pressure. However, you can manage the problem on your own without special skills.

You have to analyze the orifice. When you have noticed any issue with the orifice, you have to replace it.

The leaking water is another reason for this problem. Take the right steps to repair leaks.

The pressure sensor helps in identify the pressure of the pump. The pump will be shut down due to the low pressure level.


Why is garnet the best abrasive for your waterjet cutting system?

Abrasives are one of the important elements needed for your waterjet cutters. You know that pure water can cut through softer materials, like rubber and foam. However, the use of abrasives increases the cutting capacity of the jet. By applying abrasives, you can cut metal, glass, and stones.

Professionals have thoroughly tested different natural and synthetic materials used as waterjet abrasives. They have found that garnet is the acceptable garnet in the industry. Moreover, garnet has the perfect combination of density, durability, and shape to increase the cutting potentials. It is also chemically alert helping you to get the best result.


How are river garnets different from rock garnets?

Alluvial (river garnet) garnet is common in a few countries, as it is found as deposits in natural hollows and river beds. The consistent flow of water has smoothed it. Beach garnets and river garnets have no difference.

Another commonly used garnet is the rock garnet. It remains embedded in rocks and is crushed in mills. Due to the thorough crushing process, the garnet has very sharp edges. It is better and more acceptable than other available types of garnet.


Is abrasive waterjet cutting a costly process?

In your waterjet cutting projects, abrasives cover the major cost. You can find differences in the cost for abrasives. The abrasive quality is another factor causing variation in the cost. As the crushed garnet gets blended with some other minerals, its cost is higher compared to alluvial abrasive. The sharp grains are important for applications, like horizontal cutting. You can test the garnets to ensure that you are going to invest in the right type of abrasives.


What should be the mesh size of garnet?

In most cases, you will find smaller size abrasives. Thus, 100 mesh abrasives are smaller compared to the 80 mesh ones. While cutting through the softer and thinner materials, you need quality finish. That is why finer abrasives (like 150 and 120 mesh) are the right choice.

While dealing with thicker and harder materials, you have to select coarser abrasives (50 mesh). You will find a smoother surface finish with 100 and 150 mesh. However, the most popular one of them is 80 mesh abrasive. It has a range of applications.


How much abrasive is essential for your water jet cutting process?

You know that by using abrasives, you can make the cutting process more efficient. The waterjet uses 0.3 lb/min to 0.2 lb/min of abrasives. It indicates the flow rate of the abrasives. Based on the nozzle and the pump size, you will find a difference in flow rate. In most cases, you need 1 lb of abrasive in a single minute for every cutting head.
