[0002] Waterjet cutting, also known as water knife, is a high-pressure water jet cutting technology. It is a machine that uses high-pressure water flow to cut. Under the control of a computer, it can carve workpieces at will and is less affected by the texture of the material.

[0028] Working principle: When in use, the worker places the chip to be cut on the upper surface of the storage table 19, and the first cylinder 14 above the corresponding two ends will drive the seat 16 to approach the two corners of the chip, so that the rubber pad 17 on the surface of the seat 16 fits the corner of the chip to fix the chip. Then, under the connection of the controller 8, the vertical drive mechanism 5 and the horizontal drive mechanism 35 can correspondingly drive the moving table 37, the booster pump 2, and the cutter 38 components to cut the chip. Then, at this position, the hydraulic cylinder 23 drives the connecting block 22 to move up, and the sliding frame 18 can drive the second cylinder 40 and the card shell 27 moves to the position below the chip, and then the second cylinder 40 drives the card shell 27 to the side close to the chip, so that the cleaning cotton 24 is attached to the surface of the chip and moves from top to bottom. During the wiping process, the drying air pump 26 conveys the dry airflow to the inside of the air storage pipe 28 through the conveying pipe 25, and the airflow is sprayed out through the multiple groups of spray bottles 30 inside the air storage pipe 28. The dry airflow diffuses to the outside through the inside of the cleaning cotton 24, so that the chip surface can be dried quickly when cleaning water stains. This method is suitable for water jet cutting, and the surface of the cut chip can be wiped by itself, thereby improving the cutting effect.
