How powerful can soft and weak water be, if water can cut diamonds, can you believe it?
In addition to being able to cut diamonds, it can also cut tens of centimeters of steel plates, and even open the axe and cut iron like mud.
Why is the weak and boneless water so powerful?
Water can cut through everything, because water can be a knife, that is, a "water knife", which is called high-pressure water jet cutting technology.
This technology was originally invented by the Americans and applied to the field of space technology. But at that time, waterjets were a new type of tool, without the sense of technology of electronic products and the metallic sense of mechanical products, so they did not pay attention to it at that time.
Until 2011, Ji Xingang, a waterjet expert in China, innovated the waterjet, breaking the pattern that the waterjet could not be used in dangerous areas and was widely developed and utilized. At present, waterjets are developing towards intelligence, and there have now been three axes, four axes, five axes and even robot water cutting.
The biggest feature of waterjet is the one-time cutting of any curve on any object. And the waterjet is cold cutting, will not make the material chemical reaction and physical reaction, will not produce toxic substances, so the waterjet is favored by everyone.
After continuous improvement, the speed, thickness and accuracy of waterjet cutting have been greatly improved. Waterjets are now widely used in ceramics, metals, glass, wood and composites, and also play an active role in aerospace, medical, blasting, power, petrochemicals, ships and construction.
What are the advantages of waterjet compared to other cutting methods?
The first is laser cutting. Laser cutting is very fast and precise, but laser cutting is too expensive compared to waterjets. Moreover, laser cutting will produce a high temperature, when cutting aluminum, copper and thicker steel plates, the effect of laser cutting is not good, it is likely to burn out the material. Compared to the two, the waterjet has a smaller investment, a wider cutting range, no worse speed, and most importantly, no destructiveness.
Look at plasma cutting. Plasma cutting is not as good as laser cutting, it not only generates heat, the accuracy is relatively low, and the surface after cutting is difficult to reprocess, which is equivalent to a piece of "waste". Compared with the two, "water cutting" will not deform the material, the cutting quality is better, and it is easy to reprocess.
There are other punching and shearing processes such as cutting, flame cutting, etc., which are also very restrictive. In contrast, "water cutting" has become the boss of the cutting world.
In fact, waterjets are not only mixed in the cutting world, but also play a huge role in the ultra-high pressure water jet in the cleaning field.
Ultra-high pressure water jet cleaning technology is a high-tech technology developed internationally in recent years, which mainly cleans the surface stains through high-speed water flow. In addition to the most common car wash in life, it can also clean the dirt inside the equipment and play a dredging effect.
Compared with traditional manual, mechanical cleaning and chemical cleaning, ultra-high pressure water jet cleaning technology has simple operation, low cost, no pollution, no secondary injury, no space restrictions, and no special requirements.
"Waterjet" is precisely because it is not a "knife", so it has opened up a place of use!
