What Exactly Goes Into the Maintenance of a Water Jet Machine?

End-users of abrasive waterjets machines often underestimate the maintenance requirements of new machines. Most of the time, unexpected maintenance downtime can easily slide to becoming a major setback that leads to a longer return on investment.

To remain profitable, it is paramount for owners of manufacturing companies to know exactly how to account for maintenance costs. These may include the abrasive-feeding apparatus,  high-pressure supply lines, cutting head, pneumatic tubes,  and of course the pump itself.

Looking Into the Big Cost Picture

Waterjet machines that frequently use abrasive garnet particles are actually most susceptible to self-destruct. When 50,000 pounds per square inch (psi) of water pressure is compounded with abrasive materials, any component or section of this kind of device that makes close contact with either of the two elements—or both—will be calling for a replacement at some point.

Due to the surge in consumable demand and downtime to fix or upgrade products, the typical cost of running a waterjet, including the cost of the unit, overhead, and operator cost, will likely come close to around $85 per hour. With respect to prevailing market conditions, this high cost will create a substantial impact on the anticipated earnings of every end-user. 

Fabricators would benefit from the maintenance checklist we prepared and presented below, that is if they want to have a better understanding of their waterjet cutting machines. In doing so, they will figure out the best opportunities that will allow them to keep their operating costs low, and their downtime runs to a minimum. 

Check Out the Water Quality

Fabricators should be more concerned about the quality of the water they are using on their waterjets in their shops if they are concerned about water quality at their homes. When it comes to managing consumable prices, this aspect may be considered as having the most significant impact. Industry experts say that the use of hard water is likely to cut the average duration of consumable items in half.

It is best practice for any fabricator to monitor or have a close eye first on the incoming water before making any decision to purchase a unit of water jet machine. If the waterjet is to be used under normal conditions, then the water quality must be adhering to the manufacturer’s requirements. 

Most pump companies have a greater preference for less than 100 PPM or parts per million of total dissolved solids (TDS). This measurement monitors the concentration of dissolved inorganic solids in water that correspond to hardness, such as calcium and magnesium. 

If TDS, or total dissolved solids, is less than 10 PPM, it can also lay the groundwork for a slew of problems since it is possible for water to leach material from any object with which it comes into contact.

Inspect the Mixing Chamber

The abrasive particles are drawn into the water jet machine stream in the mixing chamber. They are accelerated up to 2.5 times the speed of sound speed.

Even under normal day-to-day use,  the mixing chamber will remain susceptible to the usual wear and tear after about 500 hours. If you want a brand new unit, you will have you shell out between $100 and $200. Installation time is fast and easy,  estimated to take around 5 to 10 minutes only.  

opt laser

If the mixing chamber and the water nozzle are misaligned, the mixing chamber may need to be replaced abruptly. As a result, the waterjet stream will cut into the mixing chamber. 

If the abrasive is not properly screened, clogging in the mixing chamber may take place as well.

Check the Connections, Hand Valves, and Final Filter

A fabricator must trace the water path from the pump to the cutting head if he seriously wants to obtain an accurate count of the number of elbows, T’s, hand valves, and other connectors a waterjet system has. These kinds of products normally have a lifespan of 1,000 to 2,000 hours and may come in a price range between $50 and $200 to replace.

The final filter process extracts any debris from the water before it gets to the cutting head. The filter can be simply cleaned or maybe needing a replacement already, depending on the design it came in.

Why Garnet is the Preferred Abrasive Material for Water Jet Cutting Machines?

Abrasive materials can be lined up as one of the vital components of any water jet machine cutting process. When you add abrasive substances to the water itself, particularly garnet particles, that is the time that you can intensify its cutting power and thus can be used for cutting tough materials like metals. Water jet machines that are not using abrasive materials are usually utilized for cutting “softer” materials instead such as rubber and foam.

As one can imagine, the type of abrasive material that can be used for this purpose is paramount to determining the level of success a waterjet-based machining process will have. Abrasive garnet materials offer waterjet machine operators a rigid and reliable substance that will form sharp edges when fractured. This measure paves the way for it to have that superior cutting power.

Professionals before have tried and tested a sundry of materials to identify the most effective abrasive substances that can be used for water jet machine cutting purposes. But garnet abrasive stood out among others and, thus, became the abrasive material of choice by the industry itself.

What makes Garnet Ideal for Waterjet Cutting Machines?

Industry insiders commented on this and asserted that garnet, as an abrasive material for waterjet system of cutting, offers users the right combination of density, durability and particle shape that maximizes the cutting power of standard waterjet systems.

Above that, garnet is qualified as an inert type of chemical. What does this signify then? It means to say that it is not likely to have a poor reaction with whatever materials you are trying to cut.

Choosing the Correct Garnet

When it comes to cutting, not all garnet is good for this purpose. It‘s because you will find some garnet solutions out there as far more effective compared to others — despite the fact that these minerals have an almost identical chemical makeup.

It is estimated that around 70% of the operating costs involving waterjet machining would account for abrasive. With respect to this, the kind of garnet abrasive material you will decide to utilize for any particular project will have a significant amount of impact on how successful the project will be as well as the economic side of things, too.

Garnet can be found in a wide spectrum of grit sizes, each designed and intended for different results. With respect to the hardness level of the machining material you are working on, the finish can come out rough or smooth.

In most cases, fabricating firms will need to make use of finer grits on projects that require smoother and higher edge quality. As for the large-sized grits, they are most effective when utilized on projects that necessitate faster cutting.

waterjet cutting method

Usually, what happens when fabricating firms purchase garnet abrasive material, they’d receive it on their end in a sand-type form. It will be run first via a screen initially. This measure will allow them to obtain first the exact sizing they require.

They also come in a spectrum of “mesh” sizes, and fabricating firms would be choosing mesh sizes with regard to the material they are working on to cut. Generally speaking, mesh sizes can be found in the range of 50 to 200. This would be indicating the size of the garnet abrasive substance in “microns”.

Using Garnet for Your Abrasive Waterjet Cutting Machine

Standing next to diamond in terms of hardness and other similar minerals, garnet made it to the top choices for the majority of abrasive waterjet projects. Depending on the hardness, sharpness, shape, and purity, some garnet materials would be better for cutting works. And yet with regard to their sharp edges, durability and low chemical input, they are ideal for use to cut almost any material.

Important Facts on Abrasive Water Jet Machine

Evolving, changing, developing. These are the adjectives that best describe the current state of abrasive water jet cutting today. It has been so for the last 30 plus years and counting. As always, there is a trove of useful and relevant information about this subject on the Internet, but in the meantime here are some of the observations we have about the water jet cutting method.

What is an abrasive water jet machine?

As the name itself suggests, the roots of this modern method of cutting materials are in the use of water. Water in a comparatively low amount of pressure has been used in cutting out “soft” materials, including paper and sometimes, even food. This came about as early as the 1930s.

Over the years, the emergence of high-pressure technology water came to the surface and became exceptionally useful. In later years, the technology was further developed and fine-tuned. What we have today, abrasive water jet cutting is the result of these series of evolutions for this kind of technology in the material cutting industry.

In the basic sense, an impressive abrasive water jet cut can be achieved by making use of a stream of high-pressure water mixed with abrasive particles like garnet fibres. The stream of high-pressure water is directed onto the workpiece. Cutting the parts to shape and fashion it into your desired form is done by eroding the surface of it. By adding granular abrasives to the water, its “gentle” cutting power is further intensified.

When the abrasive particles in the water reach the nozzle, you have the liberty to switch between water with abrasive particles and just water-only. This measure allows the water cutting machine operator to use the water-only feature of the equipment for positioning purposes, then eventually to the abrasive option for the workpiece.

Abrasive water jet machines are usually grouped with methods of choice, such as oxy-fuel cutting, plasma cutting, and laser cutting. The common denominator shared by each of these material cutting methods is that they allow users to cut out complex shapes in the C/Y axes on a flat sheet material.

The one technique that comes with the lowest operating cost among the group is the plasma cutting, yet it can be considered as the most brutal while at the same time tends to make the largest kerf.

In the case of oxy-fuel cutting, it tends to produce a rather smaller kerf with smoother edges and ends. Abrasive waterjet cutting is more advantageous than many other kinds of cutting methods in such a way that it doesn’t produce heat. But it can also cut through non-metallics, yet tend to produce smaller kerf. In major applications, laser cutting is the main challenger for waterjet cutting. Among these 4 methods of cutting, it produces the smallest kerf.

To Use or Not to Use Waterjet Cutting Machine?

There has to be a few good, underlying reasons why anyone would be choosing an abrasive water jet machine instead of other available material cutting methods, from say a large sheet of material down to cutting complex shapes and intricate forms – or even laser cutting, plasmas or oxy-fuel.

We can just opt to leave the discussion here to the hands of the experts in these methods. When it comes to applications like a 2-axis cut-off of small precision rods, tubes, and wires, other available material cutting techniques often prove to be a better choice.
