Waterjet Machining

Waterjet Machining -- Its Time Has Come
Waterjet machining has been around for many years, but has traditionally been viewed as a specialty process with limited applications. However, recent advances are making waterjet machining practical for applications never before considered.

The waterjet cutting machine uses a stream of water and abrasive particles, such as garnet, to perform the cutting operation. The waterjet cutter takes city water (typically 80 psi), and through the use of an intensifier-type pump, pressurizes the water to 55,000 psi. When the abrasivejet cutting head is enabled, the water flows through a 0.010-inch diameter orifice into a mixing chamber. As the waterjet stream enters the mixing chamber, it creates a partial vacuum that draws the flow of abrasive particles through the abrasive delivery line. The abrasive particles combine with the waterjet stream to create the high energy abrasivejet cutting stream. This stream exits the cutting head at a velocity of up to 3,000 feet per second. Today's waterjet cutting machines are CNC controlled for accuracy, repeatability and ease of setup.

Advantages of waterjet machining:
- Cuts through any substance

- Material yield is maximized. Parts can be nested very close to each other in order to maximize material utilization. In some cases, pieces can even share the same cutting line.

- No heat-affected zones the waterjet process does not generate the same level of heat as other processes. As a result, the properties of the materials being cut do not change. The waterjet heat is concentrated so much that it literally dissipates into the chip or removed material. He adds that there will be no burn marks on parts that have been cut by the waterjet.

- No start hole is required The waterjet nozzle is placed where the cutting is to begin. The waterjet burrows its own hole through the material, eliminating the need to drill the material beforehand.

- Burr-free edge quality. The waterjet cuts with very little force, so the amount of burr generated is either very small, or non-existent.

- Eliminates secondary operations. In many cases, the need for secondary operations, such as sawing, milling or drilling can be eliminated. Etching of numbers can be done during the waterjet process, eliminating the need for a separate etching operation. In addition, because the waterjet cuts without heat, there is no need to anneal the material after machining.

3D Waterjet Cutting Technology

The Mach 4 cutting system combines a HyperJet pump, rated at 94,000 psi, with Dynamic Waterjet XD, a high-precision flat stock and 3D waterjet cutting technology. The combination is said to improve part cycle time and accuracy.

The accuracy and speed that Dynamic Waterjet applied to 2D cutting is now available for cutting bevels and 3D parts with the patented Dynamic XD. Now manufacturers can accurately cut a variety of intricate designs, often without any secondary processing.

The HyperJet pump delivers a stream of water at nearly four times the speed of sound, the company says. Increased pressure increases productivity. Waterjets equipped with HyperPressure systems running continuously at 87,000 psi cut as much as 50 percent faster while using less abrasive than conventional waterjets, the company says. Parts can be cut with a lower cost per part, and more jobs can be completed in less time.

3D Waterjet Cutting Technology

Cost-Effective Waterjet Technology
The Hydro-Jet Eco is described as a high-precision, low cost waterjet cutting system. The unit offers a compact design and cuts virtually any type of material including metal, composites, plastic and more.

Equipped with a software package for quick programming on an integrated PC control with graphical user interface, the waterjet technology features a cold-cutting process that ensures distortion free fabrication, the company says. This pure water and abrasive cutting equipment is said to ensure precise cuts without any heat-affected zone. The working area is 60 ″ × 24″ along with positioning accuracy on the X axis of ±0.001 inches per foot and Y axis of ±0.0007 inches per foot, allowing for complex cuts and small kerf widths for better material use as well as seamless nesting.

The Water cut

The waterjet features a maximum feed speed of 160 ipm with a repeatability of 0.0007 inches per foot. The unit comes with an integrated high-pressure 10-hp pump.

In Waterjet, Fast Cutting Found at Lower Pressure

In abrasive waterjet machining, does higher pump pressure translate to faster cutting?
Power is proportional to flow times pressure, he notes. As a result, “for a given electrical input power, any increase in pressure must be matched by a decrease in volume flow rate. This means that a higher-pressure pump must use a nozzle with a smaller orifice.” Thus, the 50-hp pump that would use a 0.014-inch nozzle orifice at 60,000 psi is constrained to a 0.010-inch orifice at 90,000 psi,

Water jet cutting machine

In waterjet applications in soft materials where the water alone does the cutting, a smaller-diameter jet stream might be more effective. But in abrasive waterjet applications, it’s the abrasive doing the cutting rather than the water. The water’s role is to accelerate the abrasive particles. A smaller-diameter stream “actually carries less momentum for entraining and accelerating abrasive particles than a lower pressure jet of the same horsepower

Water cutting products

Efficiency might be the better indicator of cutting performance. That is, how well motor power is converted into power at the nozzle. A direct-drive pump delivering 60,000 psi features lower efficiency losses than pumps designed to achieve higher pressure, Dr. Olsen says. This means less of the power of the motor is wasted as heat. He says a 50-hp direct-drive pump can deliver about 45 hp to the nozzle. Higher-pressure pumps potentially impose greater power losses than this. They also impose costs related to the added strain of the higher pressure on the machine’s valves, tubes and fittings. Because of all of these costs, he argues that there is significant value in discovering just how much cutting performance a 60,000-psi waterjet machine can deliver

Why Not Waterjet

Manufacturing is always looking for ways to lower its costs and increase its throughput while maintaining quality. The drivers for these continuous improvements come from customers who are themselves driven by market forces beyond their control. The impact is a general and universal acceleration of the manufacturing process--from design to delivery--across the manufacturing landscape.

In response, shops of all stripes are looking for ways to satisfy these customer-driven demands. For metalcutting shops, the search often takes them beyond the realm of what many consider traditional metalcutting technology.

Water cutting machine

Abrasive waterjet technology is one of the newer cutting systems available in today's market. They are quick, flexible and effective in meeting a wide variety of challenges among manufacturers. Years of development have resulted in improved wearability and control technology, making waterjet cutting systems competitive to other cutting methods.

Materials And Capabilities
The list of materials that a waterjet system will penetrate is significant. To date, applications have been used with foam, GIO phenolic, steel, armor plating, urethane, titanium, Kevlar, aluminum, linen phenolic, brass, neoprene, copper, stainless steel, spectra, fiberglass, corrugated cardboard, acrylic, ceramic tile, wood, rubber, glass, marble and granite.

Waterjet systems are also an attractive alternative to surface preparation. They strike a surface with such impact that coatings are instantly removed without the side effects of noxious dust that other methods may create.

The advantage of a waterjet cutting system is not limited to the wide variety of materials through which it cuts. Its effectiveness comes not only from what it does, but also from what it does not do.

Waterjet systems are an ideal process solution for cutting materials that are heat sensitive. Because it produces no HAZ (heat affected zone), waterjet is a candidate for applications where thermal induced micro-fractures or distortions are unacceptable. Waterjet's relatively cool cutting makes it temper neutral. Its cutting action will neither harden nor anneal an application material.

Environmental concerns related to the cutting of hazardous materials such as asbestos and fiberglass are reduced through the use of a waterjet cutting system. Airborne contaminants and fumes are significantly reduced or eliminated.

The erosion process of abrasive waterjet cutting creates no burring or rough edges. Often the necessity of additional finishing operations is eliminated.

There are no start holes created and parts can be optimally placed to fully utilize a piece of material. It also eliminates the distortion from compression that is created by traditional die cutting methods.

Five-Axis Waterjet Cuts Virtually any Material

Jet Edge’s Idro line of five-axis precision waterjet cutting machines is capable of cutting virtually any material, the company says. The line is available in three sizes: 5.5 × 6.5 ft., 5.5 × 13 ft. and 6.5 × 13 ft. nominal (1,700 × 2,000 mm, 1,700 × 4,000 mm and 2,000 × 4,000 mm). All models feature the IKC five-axis waterjet cutting head, which is capable of making inclined cuts and controlling kerf to ensure optimal part quality. The cutting head features 600-degree rotation, a maximum angle of ±60 degrees and dynamic precision from ±0.2 to ±0.5 mm/ m, depending on the tilt of head.

Five-Axis Waterjet Cuts

The line’s high-precision, ground, rack-and-pinion X and Y axes, as well as its ballscrew-driven, 5.9" (150-mm) Z axis, ensure accuracy, the company says. It maintains a cutting tolerance ±0.004" (0.1 mm/m) and repeatability of ±0.001" (0.025 mm). The machine also supports a contouring and rapid feed rate of 0 to 1,575 ipm (0 to 40,000 mm/min.) Motion components are protected by steel covers with labyrinth lip seals to ensure lasting performance.

Five-Axis Waterjet Cuts

The line is equipped with programmable contact height sensing and one five-axis cutting head. A second five-axis or three-axis cutting head is also available. Other standard features include a stainless steel tank; automatic safety guards with clear windows on front and back; and a dredge conveyor for abrasive removal. Options include a rotating axis for pipe cutting, a fire jet etching system, a drill and twin shuttles. According to the company, free software updates are included for the life of the machine. The machine’s rigid, fixed, upright bridge structure can be moved out of the way for forklift or crane loading.

Waterjet In Action

The advantages that Airbus cites—faster cutting and avoiding damage to the workpiece—are among the main benefits aircraft manufacturers seek through machining composites with waterjet. Other benefits include:

- No dust. Fine dust from machining composites can infiltrate controls and other electronic equipment in the shop. It also makes the shop grimy and unappealing. With waterjet, this dust is contained and controlled. For the most part, the dust is carried away with the water, from which it can later be removed.

Waterjet In Action

- No heat-affected zone. Delamination and fiber pullout are not the only dangers of mechanical cutting. Another is heat, which might melt the matrix of CFRP. But waterjet is inherently a cool process. Heat generation is slight, and the water transports the heat away.

- No rigid clamping. An unsupported edge of a CFRP workpiece is prone to vibrate during milling. For this reason, machining of composite structures on routers or similar machines often involves elaborate tooling designed to carefully and rigidly clamp the work at every trimmed edge. Vacuum fixturing built to the precise contours of the part is common. But with abrasive waterjet, the force of cutting is slight. The force also pushes down against the support beneath the part. Therefore, while programmable workholding is sometimes used (see below), rigid custom tooling is not required.

Water cut in Action

Aircraft Equipment
That “programmable workholding” is one of various features Airbus specified to allow its waterjet machines to be adapted to the particular needs of complex aircraft parts. Work is supported atop a flexible header system consisting of an array of effectors that resembles a bed of nails. Each effector’s vertical position is set independently, so the overall array can follow the contours of the part. Changing from one part number’s positions to the programmed effector positions for a different part takes only about 2 minutes, Mr. Saberton says. This compares very well to the hours that might be required to move one custom fixture off the machine and replace it with another hard fixture. Mr. Morazo-Perez says Airbus initially questioned this approach to workholding—worrying in particular whether the flexible tooling would stand up to the water over time. The company became convinced after visiting shops using similar programmable workholding on waterjet machines in the U.S.

Other machine features particular to aircraft abrasive waterjet machining include:

- Side-fire nozzles. Aircraft skins can include small ribs and stringers that impede access. The machine’s ability to switch to a nozzle that redirects the jet to the side can be useful for cutting within these tight spaces.

- C-catcher. The contours of aircraft structures can double back upon themselves, meaning the jet of water exiting the cut might hit some other surface of the part. To prevent this, a C-shaped catcher (see photo) can intercept the exit side of the jet. A consumable inside of this device absorbs the energy of the jet so the water can be captured and reclaimed.

- Rotary spindle. As Airbus indicated, rotary-tool machining remains useful in many composites applications. In fact, certain features must be machined in this way. While waterjet can machine a hole, for example, it can’t machine a countersink. Therefore, some abrasive waterjet machines incorporate rotary spindles for such needs as this. The rotary spindle is also useful for marking tools.

Waterjet Basics

This non-traditional application of abrasive waterjet may interest some to whom waterjet machining is an unfamiliar process, so here is a brief primer:

Abrasive waterjet machining can be thought of as a water-driven grinding process. A narrow, high-pressure jet of water carries particles of garnet abrasive at speeds ranging from 1,000 to 2,400 feet per second. This garnet does the cutting. And there are few materials, metal or non-metal, that cannot be cut in this way. In metalworking, abrasive waterjet machining often finds work cutting hard steels, aerospace alloys, and other materials that are difficult to machine through a more conventional, mechanical cutting process. However, waterjet machining also offers other advantages. One is that it's a "cool" process. Because there is no heat-affected zone, waterjet is a candidate for applications where thermal-induced micro-fractures or distortions in the part are unacceptable.

Abrasive waterjet machining - Process

This article uses "waterjet" and "abrasive waterjet" interchangeably, but it's worth noting that the terms are not necessarily synonymous in larger contexts. There is such a thing as pure waterjet cutting used outside the metalworking industry. But in the context of machining metals and other hard materials, "waterjet machining" can be assumed to mean abrasive waterjet machining, with the hard garnet particles added to the jet.



Historically, controlling a waterjet's depth of cut has been difficult. That's why waterjet machining is typically used in applications where depth of cut doesn't matter. These include applications where the jet passes all the way though the workpiece, like slotting, drilling, and machining cut-outs. Machining when the jet does not pass all the way through has traditionally been limited to "artistic" purposes, like etching and labeling.

Waterjet milling does add control over depth of cut. Thanks to this addition, waterjet cutting when the jet does not pass all the way through can be used not just for appearance effects, but also to produce features that are functional.

Effective For Water Jet Cutting Machines.

Water jet cutting machines has the advantage of not manufacturing mud particles. This could permit alternative close activity to require place about unlimited. Water jet cutting machines will clean surfaces to the best potential customers, provide the simple surface preparation for water jet. Water jet machines may be powered by an electrical motor or a diesel engine in usa. They will be provide as high pressure or ultra high pressure devices. Water jet cutting machines of applications they will certification is exciting. With the exception of surface preparation they will be used for cleaning tanks and vessels. They will even be used for cold cutting.

Waterjet Cutting Machine

In cold cutting a high pressure water jet is employ together with a pointy edged abrasive compound. This works well on steel and concrete in addition as on alternative materials. Very little or little heat is generated for about makes this cutting methodology terribly appropriate in cases where the same old heat generate by cutting is undesirable.

Water jet cutting machines is probably dangerous as an especially performance pressure of water is employed. For this reason operators should be properly and should wear the right safety garments and equipment. For obvious reasons the operators concern in cold cutting don't stay near the cutting jet. It's operated at a secure and remote distance.

Water jet cutting machines are helpful in remove scale from the within of pipe work. By necessity the equipment use in these cases involves the employment of tiny injection heads which will enter pipes of a tiny low diameter. As a result of pipes usually have bends, the water jets conjointly got to be versatile enough to address the changing conditions it'll encounter. This can be by necessity a remote management operation and variable speed control permits it to manage all seemingly things

Why Choose Water jet Cutting?

Water Jet Cutting Services – Why Choose Water jet Cutting?
Water jet cutting services are widely used in engineering and building circles to cut a variety of materials. Water jet cutting differs from laser jet cutting in several ways. Understanding these differences will aid you, as a hobbyist or a professional, to select the best suited cutting method for your specific requirements.

Waterjet cutting Machine

Waterjet cutting uses a highly pressured jet of water to cut through materials. The high level of pressure required is achieved through forcing the water through a tiny opening at pressures of up to 60,000psi.

To further enhance the cutting action, a material called garnett is added to the water to increase the abrasion.

The resulting cutting action is similar to that of water naturally cutting its way through the earth, forming river beds over thousands of years, but performed in a fast and precise way.

This is abrasive cutting' can cut through a variety of materials, and a large range of thicknesses, which is where water jet cutting holds advantages over laser jet cutting which has a limited range of materials and thicknesses on which it is effective.

The variety of materials that can be cut using a water jet include;
Metals – aluminium, brass, bronze, steel, titanium, copper, other metal alloys

Ceramics and Stone – granite, marble

Composites

Concrete

Glass - fiberglass

Plastics and rubbers – Kevlar, foam

Wood

Depending on the material, the thickness can be up to 8" thick with tolerances as little as 0.005" – 0.010".

Water jet cutting uses no heat, so it is well suited to materials that are damaged or adversely affected with the application of heat. Waterjet cutting leaves the structural integrity of materials intact, meaning it can be used on plastics, wood and other materials which cannot be cut using a laser cutter.

Selecting the right cutter for your engineering or building project can save you money, time and the expense of having to replace a sheet or length of building material because of an imprecise cut.

Waterjet cutting glass

Cutting Glass
Although glass is a brittle material, it can be cut using an abrasive waterjet and the results can be quite stunning. Most glass cutting is done for artistic purposes.

There are a few main items to consider when cutting glass:
- Quality of glass
- Abrasive and water delivery
- Support of the glass
- Design of the part



Quality of glass
Some types of glass cut much easier than other types of glass. Generally speaking, higher quality glass that is thicker tends to be easier to cut than low quality glass or thin glass. The manner in which the glass was cooled at the factory affects the temper and how brittle and how difficult it is to cut later on, and some of the cheaper glass is not as good.



Tempered glass is impossible to cut with a waterjet, as the glass is under stress. When you begin cutting it, tempered glass will shatter into many small fragments.

Cutting Titanium with Water Jet

Waterjet cutting titanium
Water jet cutting is a recent innovation in cutting titanium. A high speed jet containing entrained abrasive is very effective for high cutting speeds and for producing smooth burr-free edges. Sections up to three inches have been cut and the process is relatively unaffected by differences in hardness of the titanium workpiece.






Titanium can be economically machined on a routine production basis if shop procedures are set up to allow for the physical characteristics common to the metal. The factors which must be given consideration are not complex, but they are vital to successfully machining titanium.

The different grades of titanium, i.e., commercially pure and various alloys, do not have identical machining characteristics, any more than all steels, or all aluminum grades have identical characteristics. Like stainless steel, the low thermal conductivity of titanium inhibits dissipation of heat within the workpiece itself, thus requiring proper application of coolants.

What kinds of materials can be waterjet cut

What kinds of materials can be cut with a waterjet?
A waterjet cutting machine can cut both hard and soft materials. Soft materials are cut with water only, while hard materials require a stream of water mixed with fine grains of abrasive garnet. Materials including, titanium, stainless steel, aluminum, exotic alloys, composites, stone, marble, floor tile, glass, automotive headliners and door panels, gasket, foam, rubber, insulation, textile, and many more.

Waterjet cutting material

Will waterjet cut any material? What are its limitations?
There are some types of materials that are typically not good for the Water Jet Applications. Depending on the end use, wood is often a poor application, due to its fibers' absorption of water, which causes them to splay and become rough. Many fabrics do not cut well, as the fibers "squirm" out from under the cutting stream, rather than remain in place during the cutting process.

A few materials require the waterjet to cut through one layer, cross a void, then cut through another layer does not produce desirable results. The cutting stream does not remain cohesive after cutting through the upper layer, causing a poor edge quality on the next layer.

Advantages to Waterjet Cutting Machine

Advantages of Waterjet cutting
Waterjet cutting has many applications, and there are many reasons why waterjet cutting is preferable over other cutting methods. Listed below are several advantages, along with a brief explanation.

- In waterjet cutting, there is no heat generated. This is especially useful for cutting tool steel and other metals where excessive heat may change the properties of the material.

Advantage Waterjet Cutting Machine

- Unlike machining or grinding, waterjet cutting does not produce any dust or particles that are harmful if inhaled.
The kerf width in waterjet cutting is very small, and very little material is wasted.

- Waterjet cutting can be easily used to produce prototype parts very efficiently. An operator can program the dimensions of the part into the control station, and the waterjet will cut the part out exactly as programmed. This is much faster and cheaper than drawing detailed prints of a part and then having a machinist cut the part out.

- Waterjet cutting can be easily automated for production use.

- Waterjet cutting does not leave a burr or a rough edge, and eliminates other machining operations such as finish sanding and grinding.

- Waterjets are much lighter than equivalent laser cutters, and when mounted on an automated robot. This reduces the problems of accelerating and decelerating the robot head, as well as taking less energy.

Disadvantages of waterjet cutting method

Among the methods of cutting are cut waterjet is a process used to machine the most useful that can be replaced easily for how to cut a lot more but it has some limitations to what Steve. It can be cut million profiles. And for those who trade on the waterjet metal cutting industry, it is necessary to realize these restrictions listed below are some points that will give a brief description of each.

Waterjet Cutting Machine

1. By using a metal cutting waterjet only a limited number of materials can be cut economic. It is one of the two main items of waterjet cutting. While it is possible to cut tool steel and other hard materials, cutting rates will drop dramatically and the time to cut the part may be very long. For this reason, waterjet cutting can be very expensive and valuable than other benefits offered.

2. One disadvantage more of how to cut water jet is that it is impossible to cut very thick, with a waterjet cut may be a problem in maintaining the correct dimensions of the metal to be cut If the part is too thick jet may spread to other parts and made it on the diagonal or cut steel to be cut more than at the bottom of the top It can also cause waves on the surface of the cutting chain.

3. taper is also a problem with the waterjet to cut very thick material. Slender steel is cut off from the aircraft when part of a different angle than it goes into a part and can cause incorrect dimensions. The deceleration of the head may reduce this. But it is still a problem.

Why used Waterjet Cutting Machine

Polished blade jet balls against the tides run to cut hard objects.

Waterjet - Metal cutting

Water jet cutting is a good idea into a green technology because it does not produce harmful air and water do not cause environmental pollution. Most of the pieces of scrap can be reused sliced ​​off diving techniques to get the error by using the traditional techniques of cutting and custom. Consumption of water in the knife Water jet is very low and the water used to cut one day, can be used again by recycling, using closed-loop structure. In general, water, clean enough, or you can filter it, and allow to drain. Use a dark red polish is all harmless, because it is a natural material and non-toxic in nature and can be reused after recycling of other benefits of waterjet cutting is that you get rid of dust in the air. produced by traditional methods of cutting. This feature will seriously improve the working environment and reduce the potential exposure of workers to environmental contamination.

Waterjet cutting machine

Waterjet cutting can cut metal. Sounds impossible. But true. Diving off the process of cutting sheet metal with a high pressure stream of water containing some abrasive particles can dive off the output of any 2-D shapes from sheet metal. It can cut any metal sheet between the thickness of 0.001 "to 4 ".

CNC water jet cutting is the computer mediated water jet cutting process. In this regard, the user has to draw the design sheet metal must be cut, and software for cutting water jet CNC as follows: to cut sheet metal to shape unique CNC cut diving is advantageous as it did not leave. Any heat in the process of being cut off which may distort the sheet metal. It cuts smooth edges and any other reason, not the end, deburring to even be identified.

Maintenance of Water Jet Systems

Maintenance Waterjet cutting machine
As with any piece of equipment used in industry, waterjet cutting to maintain a regular basis to work at maximum efficiency. Maintenance can range from scuba diving off everyday tasks such as switching components injected with weekly or monthly, such as replacement of the pump. Primers, following in the maintenance of the water jet cutting.

Maintenance Waterjet cutting

- Frequency of maintenance is mainly based on the quality of water and pressure to which equipment is operated. Higher pressure and dirty water, or both, to make parts hard to break down more often. On the other hand, the water will help reduce downtime and frequency of maintenance.

- When replacing or repairing parts, be sure to clean them thoroughly before reassembling information-even a bit of dust and dirt can be a disaster jet and put more strain on the tube and mixed with other



- Run the machine at the lowest pressure possible to reduce the stress on the metal pipe. Although water will eventually have to change, lifetime can be extended significantly through the control of even low pressure. For applications such as cutting food that is not used contrary to this may be easier to use, such as glass or metal cutting.

- Fix leaks as soon as possible. Leak and cause corrosion of parts, they wear more quickly.

- Check regularly to prevent the cutting head does not put the point to begin to reduce fluctuations in the size It is also useful to log the number of hours in the cutting head and monitors performance to hours accumulated.

- Check for mixed obstruction especially if it is used for abrasive cutting process, such as granite.

- Replace the filter in the injection water as needed to maintain water quality.

- Check water pump, if possible diagnostic software. Pump is the heart of the jet cutting system and can cause a significant interruption in case of failure.

With regular care, maintenance, operators can take off and protect the best interests of this multi-purpose cutting.
