Description

Technical Field

[0002] The technical field involved in the invention of the present invention is that a water jet cutting machine is a device that uses a high-pressure water jet and abrasives to cut materials. This technology is widely used and mature, has the advantages of cold cutting, and can avoid thermal stress deformation of materials. The popular water jet cutting machines on the market are mainly large-scale CNC platform equipment with a cutting pressure of about 380Mpa, a power of more than 40kw, and a 380V AC power supply, which is suitable for large-scale and batch production fields. Compared with large-scale CNC platform equipment, desktop water jet cutting machines are more suitable for small-scale and small-batch production, especially for scenes such as laboratories and colleges. This machine occupies a small area, has low energy consumption, and has low maintenance costs.

[0003] There is currently a lack of mature desktop waterjet cutting machines on the market, and their technical features include the following: During the cutting process, abrasives and residues carried by the water jet will accumulate in the water tank.
