The main benefit of a four  axis cutting head is to compensate taper, and to make the finished it completely vertical through the fourth axis. This specially engineered cutting head has perform remote markedly in many cutting feels and reducing the processing cost of increased operating efficiency. It has a maximum limit of 4 degree angle with the rotational accuracy of 0.01 degrees.
For taper compensation, the distance between the cutting head and the surface of the work piece must be maintained with high accuracy. The height positioning accuracy of the four axis is 0.01 mm positioning cutting accuracy. 0.1 mm, which can easily meet various cutting requirements.
In the marble matching process, water jet cutting with a four  axis cutting head design is simply amazing. When the angle of the cutting head reaches 4 degrees, the finished edge shows tremendous improvement. As can be seen from this picture, there is no gap between the two joint services. Hence a secondary polishing procedure is no longer required. Thereby, it increases working efficiency and reduces the production cost.

How much do I have to spend on a waterjet cutting system? 

Caldwell Machinery offers new waterjet cutting machines starting with $50K only. A middle line of product typically goes from $120,000. We can certainly meet your customization needs. Please contact us for a free and no obligation quotation.

What tolerances can we expect from waterjet cutting?

80% of world’s abrasive waterjets have kerfs around ±0.003 inch or looser. Others may have kerfs around ±0.0005inch to ±0.001. With Waterjet technology, the tolerances will be sharper.

Should I cut underwater?
Underwater waterjet cutting reduces the noise to under 75dB and eliminates material frosting within 1/16″ from the jet. T he downside of this process is you need water level control on your catcher in order to see the underwater cutting process. Without the control, you need to work underwater and handle the cutting process.

How thick can it cut?
Operators cut up to 8-inch steel and titanium in production. There have been cases where 12″ and even 15″ thick materials have been cut. However, majority of cutting from operators ranges from 1/4″ to 2″.

What kind of abrasive are you using?
Garnet is by far the most commonly used abrasive material. It is abundant, cheap, enhances cutting speed, increases tube life and reduces health hazards. Other abrasives include olivine sand, aluminum oxide, and some man-made materials

At what pressure do you cut?
Waterjets cuts at 90,000psi. It is also the maximum intensifier pump pressure. Although higher pressures can result in higher maintenance cost on intensifier pumps especially on the seals, the result is higher cutting speed and efficiency.

What taper can I expect?
With a Waterjet system, you will experience virtually no taper. In the case of conventional waterjet cutting, the taper you get is a function of the cut speed. However, the worst taper you will get will be equal to the maximum kerf width at the top (example: 0.035″) and 0.000″. at the bottom. As you slow down the taper will be reduced until you get parallel sides. Most tapers you see on precise cuts are 0.002″ to 0.004″ on a side.

How much water will you use when cutting at 55,000 psi?
Each 0.010″ orifice uses 0.5 gpm.
Each 0.013″ orifice uses 0.82 gpm
Each 0.016″ orifice uses 1.24 gpm

When is maintenance required at the pump?
You need to replace the high pressure seal after 400 to 1200 hours of usage on a 55,000 psi intensifier and replace the seal after 200 to 600 hours of usage on a regular pump.

What is the minimum water level depths?
In most waterjet systems 36 inches of water in the catchers dissipates the energy of the jet.

How long does the material support last?
You can expect hundreds of hours of production time from the support grating before the need to replacing it. We recommend that, as long as you don’t cut just one pattern over the same section for thousands of parts, slats and grates can be shifted, swapped, and flipped just as with plasma and laser cutting. Thus, this will extend the life of the grating supports.

How long does the mixing tube last?
The highest quality ceramic carbide mixing tubes last 30% longer than other mixing tubes. A tube such as this can deliver 150 hours of cutting time for 0.020″ in diameter. Many users keep the mixing tubes longer and use them to cut parts which require looser tolerances.

How much abrasive is used?
For the most efficient cutting, cutting heads on a 55,000 psi intensifier use:
0.010/0.030     0.9 lb/min
0.014/0.040     1.4 lb/min
0.018/0.050     2.5 lb/min

What about programing A&V Waterjet machine?
Our systems are relatively easy to program as compare to any other waterjet cutting system. Our professional PC based waterjet software is capable of reading any 2D DXF files. Programming for abrasive waterjets is quick and easy. An operator with little experience should be able to learn how to program and operate the machine within one week.

What weight is required to press and hold down the workpiece?

Since the force exerted on the workpiece is very small (under 1 lb. for precision cuts and under 5 lbs. for average cuts), the need for very large and stiff fixtures is eliminated. Many customers use simple weights to hold the parts in place.

What are the operating costs of a waterjet?
Hourly machine cost ranges from $19 per hour for the small head (0.010/0.030) and up to $35 per hour for the large head (0.016/0.040). It does not include labor, lease, and depreciation.

What is the cost of the abrasive?
Abrasive will cost between $0.16 per pound to $0.40 per pound delivered, depending on the type and quantity you purchase.

How loud is it?
Noise from the waterjet is dependent upon the distance the supersonic jet is exposed to the open air. If you are cutting underwater, the noise level will be under 75 dB. If you are cutting above water, and especially if there is a large distance between the mixing tube and the work piece, the noise will be much higher, up to 95 dB. In these cases, most customers enclose the entire work area.

How do we dispose of water/garnet?
Neither water nor garnet are toxic or hazardous in any way. Water, when properly filtered for turbidity, can be flush down to the drainage systems. The garnet waste can usually be dumped in a standard landfill.

Is this pure water?
It is clean water. Most of our customers use softened tap water. Intensifier pumps should be supplied with filter cartridges that clean the water down to 0.5 micron. De-ionized or reverse osmosis systems are generally not recommended. These types of systems can make the water too clean, which makes the water aggressive and harmful to the pump.

Do you recycle the water?
Recycling systems are available. However, because waterjet systems use a small amount of water it is not economically viable for most users.

Two Types of Waterjets : Pure Waterjet vs Abrasive Waterjets


The two types of waterjets are the pure waterjet and the abrasive waterjet. Both have unique capabilities proven a benefit to industry.

iwm 5x10 Two Types of Waterjets :  Pure Waterjet vs Abrasive Waterjets

 Pure Waterjet

Pure waterjet is the original water cutting method. The first commercial applications were in the early to mid 1970s, and involved the cutting of corrugated cardboard. The largest uses for pure waterjet cutting are disposable diapers, tissue paper, and automotive interiors. In the cases of tissue paper and disposable diapers the waterjet process creates less moisture on the material than touching or breathing on it. Unplanned down time, common to other cutting processes, cost over $20,000 per hour (US dollar) in some diaper or tissue plants. The waterjet provides the 24 hour per day, 7 day per week, 360 day per year operation required by such applications – maintenance can be scheduled into production.

Pure waterjet attributes:














Pure Waterjet Cutting Heads

As you may recall from an earlier section of this document, the basic waterjet process involves water flowing from a pump, through plumbing, and out a cutting head.

 In waterjet cutting, the material removal process can be described as a supersonic erosion process. It is not pressure, but stream velocity that tears away microscopic pieces or grains of material. Pressure and velocity are two distinct forms of energy. But how is the pump’s water pressure converted to this other form of energy, water velocity? The answer lies in a tiny jewel. A jewel is affixed to the end of the plumbing tubing. The jewel has a tiny hole in it. The pressurized water passes through this tiny opening changing the pressure to velocity. At approximately

40,000 psi the resulting stream that passes out of the orifice is traveling at Mach 2. And at 60,000 psi the speed is over Mach 3.



Question: How hot is the water in a Mach 3 waterjet stream?

Answer: The water is warmed as it is accelerated to high speed. Frictional forces and other

factors warm the stream as it exits the orifice. In let water temperature provides the starting point.

Water temperature is then raised 2 to 3 degrees for each 1,000 psi. The quick answer is the

Mach 3 jet is approximately 170 to 180 degrees F.


Pure waterjet orifice diameter ranges from 0.004 to 0.010 inch for typical cutting. When waterblasting concrete with a nozzle traversing back and forth on a tractor, a single large orifice of up to 1/10th of an inch is often used.

The three common types of orifice materials (sapphire, ruby, diamond) each have their own unique attributes. Sapphire is the most common orifice material used today. It is a man-made, single crystal jewel. It has a fairly good quality stream, and has a life, with good water quality, of approximately 50 to 100 cutting hours. In abrasive waterjet applications the sapphire’s life is ½ that of pure waterjet applications.

Ruby can also be used in abrasive waterjet applications. The stream characteristics are well suited for abrasivejet, but are not well suited for pure waterjet cutting. The cost is approximately the same as the sapphire.

Diamond has considerably longer run life (800 to 2,000 hours) but is 10 to 20 times more costly.

Diamond is especially useful where 24 hour per day operation is required. Diamonds, unlike the other orifice types, can sometimes be ultrasonically cleaned and reused.

776px Evolution of the Abrasive Waterjet Nozzle Two Types of Waterjets :  Pure Waterjet vs Abrasive Waterjets

Abrasive Waterjets

The abrasive waterjet differs from the pure waterjet in just a few ways. In pure waterjet, the supersonic stream erodes the material. In the abrasive waterjet, the waterjet stream accelerates abrasive particles and those particles, not the water, erode the material. The abrasive waterjet is hundreds, if not thousands of times more powerful than a pure Waterjet. Both the waterjet and the abrasive waterjet have their place. Where the pure waterjet cuts soft materials, the abrasive waterjet cuts hard materials, such as metals, stone, composites and ceramics. Abrasive waterjets using standard parameters can cut materials with hardness up to and slightly beyond aluminum oxide ceramic (often called Alumina, AD 99.9). In the next section we will explore abrasive waterjet attributes and how the abrasive waterjet cutting head works.

Abrasive Waterjet attributes:


















Abrasive Waterjet Cutting Heads

Within every abrasive waterjet is a pure waterjet. abrasive is added after the pure Waterjet stream is created. Then the abrasive particles are accelerated, like a bullet in a rifle, down the mixing tube.

 The abrasive used in abrasive waterjet cutting is hard sand that is specially screened and sized.

The most common abrasive is garnet. Garnet is hard, tough and inexpensive. Like the pink colored sandpaper found at the hardware store, different mesh sizes are used for different jobs.

120 Mesh – produces smooth surface

80 Mesh – most common, general purpose

50 Mesh – cuts a little faster than 80, with slightly rougher surface.

The mixing tube acts like a rifle barrel to accelerate the abrasive particles. They, like the orifice, come in many different sizes and replacement life. Mixing tubes are approximately 3 inches long,

¼ inch in diameter, and have internal diameters ranging from 0.020 to 0.060 inch, with the most common being 0.040 inch.

Although the abrasive waterjet machine typically is considered simple to operate and ‘bullet proof,’ the mixing tube does require operator attention. A major technological advancement in Waterjet was the invention of truly long-life mixing tubes. Unfortunately, the longer life tubes are far more brittle than their predecessors, tungsten carbide tubes. If the cutting head comes in contact with clamps, weights, or the target material the tube may be broken. Broken tubes cannot be repaired. Today’s most advanced systems incorporate collision detection to spare the mixing tube.

The standoff distance between the mixing tube and the target material is typically 0.010 to 0.150 inch. Larger standoff (greater than 0.080 inch) can cause a frosting to appear atop the cut edge of the part. Many Waterjet systems reduce or eliminate this frosting by cutting under water or using other techniques.

The consumable items in an abrasive Waterjet are the water, abrasive, orifice (usually Ruby) and mixing tube. The abrasive and mixing tube are exclusive to the abrasive waterjet. The other consumables are also found in the pure waterjet.
