When it comes to cutting, our first impression is the cutting disc, whether it is a resin cutting disc, a diamond cutting disc, or an alloy cutting disc, the shape is similar, today we will take a look at another "non-round" cutting - water cutting.
Waterjet has the advantages of fast cutting speed, high cutting efficiency, high processing accuracy, safety and environmental protection, low cost, no dust, etc., which improves the cutting quality, narrow cutting slot, no distortion, and no grinding tools. At present, it has been widely used in glass, ceramics, steel, aluminum, cemented carbide, plastic fiber, composite materials and other material processing scenarios, and the terminal application fields include automobiles, electric power, aerospace, ships, chemicals, building materials, energy, rail transit, etc.
The basic principle of watercutting
The basic working principle of water cutting is to use water as the medium, using the principle of liquid pressurization, the mechanical energy of the power source is converted into the pressure energy of water, and then the pressure energy is converted into kinetic energy, and the huge energy is obtained through the pressurization of the high-pressure generation equipment, forming a high-speed water jet, spraying to the surface of the workpiece, when the water jet impacts the workpiece to be cut, if the pressure can exceed the damage strength of the material, the material can be cut off, and the processing purpose of removing the material can be achieved.
What is a Water Cutting Machine?
A water jet cutting machine is an industrial machine that consists of three main components that use a high-pressure stream of water to erode a narrow line through the material.
Depending on the density of the material and the compound, such as titanium, granular abrasives are added to the waterjet to increase the cutting force. The abrasive is added at the nozzle, which makes it simple to switch between using only water and cutting with abrasive.
Water-cutting nozzles
The waterjet nozzle with abrasive is configured with a mixing chamber and pipe, allowing the abrasive to be thoroughly mixed with high-pressure water for efficient cutting. The waterjet nozzle is also designed to have no abrasive mixing chamber and no piping, so that the nozzle itself is sprayed with high-pressure water, making it suitable for cutting softer materials without using abrasive solutions.
According to research data, the global water cutting machine market size will reach 86 in 2022100 million yuan, a year-on-year increase of 71%。The waterjet cutting machine market is expected to reach $2.6 billion by the end of 2030, growing at a CAGR of 78%。
After the development in recent years, China's water cutting machine technology continues to break through, the production process continues to mature, and China has become the world's main producer of water cutting machine, and some products have reached the international leading level.
Of course, despite the many advantages of waterjet cutting, it is still not a substitute for cutting discs, after all, the disadvantage of waterjet cutting is that it is expensive equipment and requires a lot of water and energy. Cutting discs are low-cost, easy to operate and maintain. So the two are more appropriately described as "working with each other". The choice of which method to use also depends on your specific needs and the type of material being cut.
