Waterjet cutting has been greatly beneficial in many applications in Melbourne. It is basically another way of cutting plastic, metal, stone and any other materials. It is, however, different from plasma and laser cutting. Waterjet makes use of high pressure cutstream of water and garnet to cut through a material. Due to its features, waterjet has become a vital part in many industries. But if you are not so familiar with it, you may wonder about the process involved behind it.
All About the Process
As mentioned, waterjet cutting has been popular in Melbourne and understanding the process behind will make one appreciate its use better. Primarily, the workpiece will be placed on top of the machine’s table. A series of clamps will be holding it in place. The operator will then communicate to a computer on what is supposed to be done. In such process that is pre-programmed and guided by a computer, the machine starts to blast through the workpiece. In this process, the water that cuts through gets reused and recycled. This makes the waterjet environmentally-friendly.
If the workpiece is thick, it can be expected that it will also take a longer time for it to cut through. Inherently, it is a slower process compared to laser cutting and working with thick materials lengthens the process even more. But its advantage is the fact that it can cut through a lot more substances.
How Does it Work?
The process will begin with a high-pressure pump. This pump can either be a direct drive pump or hydraulic intensifier pump. The latter is often used in industrial waterjet cutters wherein a series of hydraulic rams is responsible for increasing the pressure in the system to a given level. The water will then pass through a series of pressure gauges and valves before moving through the intensifier which will stimulate the force even more with the use of plungers.
When the water is ready to move to the nozzle area, it should pass through the jewel orifice. Typically, this orifice is made of precious gem like sapphire which is known to be highly-resistant to heat and pressure, as well as corrosion.
The jewel orifice focuses on the water stream downward through the nozzle. By this time, an abrasive inlet may allow grit to get through. The abrasive in this case will accelerate rapidly along with the water stream and help in the cutting process. Then the water stream will shoot downward and out of the nozzle- this is where the cutting process begins.
How About Its Benefits?
- It is a cold-cutting process
- Cuts in all directions
- May not require starting holes
- Cuts through almost any material
- Easily produces a finished product
- Does not release dust or dangerous gas
- The machine’s programming is flexible
- Faster than any other traditional cutting methods
Waterjet is such as helpful machine that involves a process that should be understood deeply by whoever is using it. But one thing is for sure, having it around can yield great benefits.
