What are the characteristics of the waterjet cutting seam and cutting section?

Even if it is just ordinary tap water, its water pressure can be increased to the required pressure through a supercharger, and it can be shot with a gemstone nozzle to form a water arrow at a very high speed, thus having a powerful cutting ability. This is water The formation process of the knife.
 
    The high-energy water beam generated by the waterjet cuts the material under the water beam to form a slit. Therefore, the size of the slit is directly affected by the diameter of the water jet water beam, and the diameter of the water beam is related to the aperture size of the gemstone nozzle. The diameter of the sand tube is related to the fluctuation of the water pressure.
 
    In addition, the size of the waterjet slit is also related to the material being cut, the abrasive and the cutting speed. Therefore, the width of the slit is not fixed, but its change is small over a period of time, so to ensure high cutting accuracy, the width of the slit needs to be measured frequently in order to adjust the parameters in time.
 
    Under normal use, when the width of the waterjet cutting seam reaches more than 2mm, it means that the sand tube has been worn seriously and has reached its service life. It should be scrapped and replaced with a new sand tube. In addition, the energy of the water jet emitted by the water jet will become weaker as the distance from the gem nozzle increases, so the shape of the cross section of the cutting workpiece will appear diagonal, and the smoother the closer to the upper surface of the workpiece, the farther away from the workpiece The rougher the upper surface.
 
    At present, the thickness of the workpiece that can be cut by the water jet can reach 100mm, and the cross section of the workpiece is relatively flat. In fact, the generation of cut cross-section twill is also related to the water pressure fluctuation of the waterjet. As long as the pressure is increased and the cutting speed is reduced, the occurrence of cross-section twill can be effectively improved.
