What Kind of Waterjet Machine Should You Use?

While water jet cutting machines are capable of quickly slicing through a variety of materials, there are occasions you will see that they perform better when used on certain types of material and would thus deliver outstanding results. 

For instance, a standard water jet can cleanly cut and slice through softer materials, whereas an abrasive type of water jet is typically intended for slicing through harder materials. 

The latter category is further classified into a slurry-type of abrasive waterjet cutting system and entrainment water jet cutting machines. Moreover, an abrasive water suspension jet is a more advanced kind of abrasive water jet. It is generally the most efficient when it comes to fast and precision cutting of hard, tough objects.

The mechanical action weakens the binding and eliminates debris from the surface, after which it can be easily rinsed away with the help of a steady stream of water. 

Components of a WaterJet Machine

The following are the basic components of a water jet cutting machine. They can be combined in a variety of ways: 

  • Machine for Memory Guidance (CNC-controlled)
  • Pipework with high pressure
  • Tank with pump for oil
  • Intensifier of pressure
  • motor powered by electricity
  • Desalination and filtration of drinking water
  • Valve and nozzle with a diameter of 0.1 to 0.5 mm

A basic water jet cutting device runs by slicing through a material with a pressurized stream of water. It is best used on soft or cracked objects so that this instrument may cut through the material neatly and seamlessly. 

Did you know that diapers, automobile interiors, and tissue paper can be cut using a standard water jet cutting machine?

Cutting Solid and Tougher Objects with Water

When it comes to harder, solid, and tough objects, you can process them using an abrasive type of water jet cutting machine. These pieces of equipment use water to propel the abrasive particles on the surface of a solid, hard material. Abrasive particles help facilitate a concentrated or intensified “erosion” on the surface of a hard material, making cutting or slicing through it possible and fast. The jet of water created is usually designed to create a tiny stream of pressurized water. 

As for the abrasive particles used, they are typically pebbles and rocks ground into a sand-like form. The materials you can cut with the abrasive type of water jet would range from stone, metal, ceramics, and an array of other similar items. 

Before pressurization takes place, the abrasive water jet slurry system blends the abrasive particles with water. Regrettably, this process sometimes runs the risk of accelerating the machine’s wear and tear. If such a scenario happens, the odds of frequent maintenance and repair are very high

While the abrasive water jet entrainment system disperses the abrasive particles in a chamber after the water has gone through the nozzle, the alternative method combines the abrasive particles right after the water passes through the nozzle. 

The particles are launched ahead of the water and are then driven out of the aperture at a velocity that’s faster than the flow of water. In many cases, this method will result in reduced wear on the machine.

Due to its fine cutting abilities, many believe the abrasive water suspension jet system ranks equally to some of the most efficient material cutting/slicing systems we have. By suspending the abrasive particles in a water-based gel, water jet cutting machines can drive the gel and direct it centrally towards the direction of the object to be cut.

As you can see, it can be used to slice through small objects such as nuts, and, as such, is commonly employed in micromachining tasks.

What Makes Waterjets Machine Dental Cleaning Better Than Regular Flossing?

Either of these two options, waterjets machine dental flossing and standard string flossing, have been shown to help maintain better oral hygiene. They can help in removing plaque, taking out stuck food between teeth, preventing cavities, gingivitis, and cleaning the gap between your teeth and gums.

However, it is important to know that the perceived advantages of waterjet flosser or dental flossing system use will largely depend upon the person’s mouth anatomy. This means to say that you might need to get used to the proper maneuver for this type of flossing just so you will get the right results. Individuals who know exactly how to floss correctly and effectively should just stick to their good practices in this area.  

But at the other end of the line, it is unfortunate to hear that there are people out there who are experiencing some difficulties with flossing while there are some also who are unable to floss at all.

Who Benefits the Most with Waterjets Flossers?

People who are made to wear bridges or dental braces, as well as those who have gum disease, may benefit more from using a waterjet machine dental flosser.

A strong stream of pulsating water is used in water jet flossers. This pressurized jet of water will significantly strip away biofilm from the teeth. Seasoned dentists recommend water jet dental cleaning to patients who are hesitant about using floss because it is much more effective.

The waterjet flosser, on the other hand, has proven itself time and again under several independent experiments headed by the American Dental Hygienists Association.

A water flosser is also more effective than string floss when it comes to irrigating pockets and plaque that are deep-seated between the teeth and deep beneath the gums. It can effectively flush away bad bacteria without any worries that afterward, you will have a bleeding gum line.  

Comparing Waterjet Dental Flossing to Traditional String Flossing

Compared to the use of string flossing and tooth brushing, the combined use of a water jet machine flossing and tooth brushing was as effective in reducing plaque and considerably better at preventing bleeding and gingivitis in a test group.

Conventional dental flossing is exceedingly challenging, particularly for people who are going through orthodontic treatment and are made to wear fixed braces. But it is worth noting that the practice of dental flossing among people with dental braces is decreasing rapidly.

If you are wearing braces, getting your floss between each tooth and cleaning around each wire and bracket is a time-consuming and frustrating process. The waterjet flosser, on the other hand, is useful for cleaning between your teeth and gums

According to surveys, most people prefer to use waterjet machine flossers but are wary of using dental floss.They despise the pain in their fingers and gums, the bleeding, and the need to adjust their jaws and hands whenever they are using string floss. 

Many people prefer manual flossing or waterjet-based types of flossers because it somehow gives them a more sense of control. It has become the method of choice of many when it comes to dental flossing because most of these people are after the deep-clean feel which water jet flossing is known to deliver. 

However, studies show there isn’t much of a distinction between flossing and water jet dental cleaning in terms of plaque removal. Both methods are just as effective as the other.

Difference Between Water Jet Cutting and Laser Jet Cutting

Difference Between Water Jet Cutting and Laser Jet Cutting

Water jet cutting and laser jet cutting are two of the most commonly used material cutting methods in the manufacturing industry. With respect to the material in question and the desired end result, either of these two options would be appropriate for a given application. By delving deeper into the fundamental differences that exist between these two material cutting methods and the range of materials that they usually work well with, we’d be able to determine when and to which project they will best work for.

Laser Cutting 

CO2 is considered as the lifeblood of laser cutting machines, it functions as its energy or fuel. This gas is being transmitted through a beam and under the guidance of custom-built mirrors, then finally directed to your material. In CO2 laser cutting machines, the source of the laser itself can be located inside the machine itself. The beam of the laser can produce an output between 1500 to 2600 watts. When trying to consider the application of laser cutting method in your material cutting requirements, applications, materials as well as precision and safety are among some of the important factors to take into account.  

Materials and Applications 

You can work with laser cutting machines with a manifold of materials. This would include wood, glass, plastic and all kinds of metals with only one exception though, the reflective type. If the material you are going to use as a workpiece is comprised of different materials with different melting points, it might pose a certain level of challenge. Sandwiched structures highlighted by cavities might not be cut by CO2 laser, and any material that eventually proves as having limited access will prove to be difficult to cut also. Cutting material for a 3D project will pose a certain level of a challenge due to the rigid beam guidance.   

Precision and Safety

Precision and accuracy have never been an issue with laser cutting. Depending on the laser speed itself, the minimum cutting slit size can reach to 0.006 inches. Thinner workpieces are at a greater risk of suffering from gas pressure in case that the proper distance is not well maintained. Partial burring is likely to occur due to thermal stress. This will render your cut material to have a striated appearance.  

While safety goggles may not be a constant requirement, the laser cutting process may produce dust and smoke. With some metals and plastics, it may run the risk of even producing toxic fumes, therefore proper ventilation would be critical. Overall, the perceived risks involved when working with a laser cutter is rather low, much like the amount of produced waste and the subsequent cleanup.  

Water Jet Technology

Contrary to how laser cutting machines work, water jet cutters make use of strongly pressurized water to cut through a wide range of materials. To further intensify its cutting power, abrasive particles such as aluminum oxide and garnets can be added to water. Overall, the water jet process is designed to imitate the erosion of the soil in the mountains and nature, just that it is done with much stronger force, greater speed, and higher concentration. 

A high-pressure pump is worked to drive water through tiny and rigid hoses. This action will result in the production of a forceful water jet. Regular water jet cutting machine typically produces about 4-7 kilowatts of output. If the laser source in laser cutters are located inside the cutting machine itself, it works pretty differently for water jets – the pump and the work area are always separate from each other.  

Material and Applications

Water jets are highly reputed in the industry due to its ability to cut through virtually almost any kind of material, even with the combination of materials. But there is one downside to the use of water jet technology and that involves the risk of delamination. 

You can make use of water jet technology with your 3D material cutting projects. But they usually tend to exhibit having a limited ability when it comes to handling sandwich cavities and structures. It is possible to work with materials that give you limited access to it but working your way through it will be very challenging or difficult.  

Precision and Safety

Compared to laser cutting, water jet technology is considered by many experts as not absolutely at par with it. Due to the high amount of force that it requires to have, thin and small parts don’t fare well, and for this reason, they need to be handled with extra care. While thermal stress is not likely to be seen as a possible issue and burring is not likely to appear in the cut, the material surface will have a sand-blasted appearance due to the abrasive material added to the water. This necessitates the use of goggles for eye and face protection. 

Water jet cutting may produce noise. Aside from which may also necessitate a good amount of clean up work to be done in the work area. The addition of abrasive material to the water may likely produce a significant amount of waste.
