Water jet cutting has sustained impressive growth in its popularity as the most sought-after material slicing and cutting process for a wide variety of materials over the years.
Compared to other cutting technologies, water jet cutting machine tend to produce cleaner results, with a greater level of precision, and lower costs without some of the downsides seen and complained about in other methods, which include roughly finished edges or thermal distortions.
Waterjet Cutting: How Does It Work?
Waterjet cutting machines start with a high-pressure stream of water that is converted to velocity through the use of a jewel orifice. This will help in the production of a stream of water as fine as human hair, yet so strong and intensely powerful that it can cut or slice through an object.
This high-velocity process can go through virtually any material. However, softer materials are sliced with fluids with a lower solubility, such as pure water, while tougher materials are sliced with materials with higher solubility, such as abrasive water.
As a result, a higher cutting velocity is produced, which leads to abrasive materials being introduced into the flow. Water acting as an abrasive forms a slurry with the consistency of liquid sandpaper that rapidly erodes the substance.
Why is Water Jet Cutting Machine in High Demand in Many Industries?
Capable of Cutting Through Any Material
Metals are the most frequently cut materials by a waterjet (especially aluminum, since it is relatively soft and thus can be cut pretty easily). Waterjets can cut a limited number of materials.
Waterjets are unable to cut diamonds and tempered glass. Diamonds are too difficult to cut, and tempered glass tends to shatter outright when cut with a water jet; however, it’s worth noting that this type of glass is designed to shatter when disturbed (the reason it is practically used in car windshields).
It is challenging to cut sophisticated types of ceramics as well as a handful of composite materials because the water is capable of pressurizing the in-between layers and in-process “delaminating” the materials.
Having said that, some composite materials may be cut fairly successfully, and there are procedures for cutting layered materials quite effectively as well.
It Takes Away the Need for Secondary Finishing
Typically, one session with the waterjet cutting Melbourne machine is enough to achieve the desired cut. Unlike other processes, this one generally does not require secondary finishing. Once the cutting is complete, it is good to go.
A waterjet system’s precision and delicacy produce a velvety, flawless edge with little kerf. Often, the wateriest come from a stream that is less than 0.02 “wide. This creates a narrow kerf that takes away a negligible amount of debris.
If the operator is handling expensive or hazardous substances, this can be quite helpful. When the kerf width is maintained at a bare minimum, you can save a significant amount of money and have more material to deal with in the end.
Cold Cutting Process
Waterjet cutting, in contrast to 95% of other cutting processes, is a qualified cold cutting procedure. Cold cutting refers to the process of slicing or cutting in which little to no amount of heat is generated on the part being cut.
If there is a tad amount of heat generated in the process, water tends to absorb it right away. When you are attempting to manufacture an end product that can not be distorted by HAZ or heat-affected zone, this edge is quite beneficial.
The HAZ is the region in which high temperatures have distorted the foundation material, culminating in structural and chemical changes that frequently result in brilliantly coloured bands encircling this zone. HAZ can distort and create damage of unimaginable proportions to components, paving the way for a poor cut that requires more work to rectify.
Since water jet cutting is a cold cutting technique, it will not cause the material to heat. A heat-affected zone or thermal deformation is not one of its attributes.
While compiling a thorough list of waterjet cutting’s numerous applications is unattainable, however, at least by now, you should have a decent sense of what this groundbreaking material cutting and slicing method is all about and its extensive capabilities.
