The high-pressure waterjet in the waterjet cutter has a strong cutting ability, and its speed can reach several times the speed of sound, and the cutting ability can be doubled by adding sand and other abrasives to it. Waterjet cutting can cut any material at one time with any curve, and does not generate heat and harmful substances when cutting, the material has no thermal effect (cold cutting), and no secondary processing is required after cutting. So what should be paid attention to in the cutting process of waterjet cutter?

　　1. Wear labor insurance glasses to avoid industrial accidents.

　　2. When cutting different materials, you need to adjust the corresponding speed, pressure and emery flow rate.

　　3. The emery must be kept dry to avoid sand blocking during the operation. When the amount of emery is small, add it in time. Do not use coarse emery during the operation. The emery must be sieved with a 60-mesh sieve before use.

　　4. During cutting, pay attention to whether the cutting is in accordance with the drawings, and pay attention to the height of the sand knife at any time, so as to avoid knife collision.

　　5. When cutting, always pay attention to the operation of the machine, check the pressure of air and water pressure, whether there is water leakage in the booster cylinder and the conduction line, and whether the motor is heating up.

     Water cutting is transformed into high-pressure water through the action of a high-pressure water pump, passing through a high-pressure pipe, and then ejected from the cutting nozzle. Because high-pressure injection is required, the diameter of the water jet is small. The water jet nozzle is generally made of high-grade cemented carbide, gemstones, etc. Made of diamonds and so on. The jetting speed of water is several times the speed of sound. This high-pressure water jet has a strong cutting ability. Some technologically advanced companies have perfected 3-axis and 4-axis waterjets, and 5-axis waterjets are also becoming mature, widely used in ceramics, stone, glass, metal, composite materials and many other industries.
