Since the waterjet sand tube is the key to the formation of the abrasive jet, it is naturally an important part of the waterjet. However, since the quality of the garnet abrasive has a great influence on the service life of the sandtube, in order to protect the waterjet sand tube , To try to choose a uniform size, clean and dustless garnet abrasive.
Less so, the model of the waterjet sand tube is different, and the type of the garnet abrasive is not the same. At present, the common inner diameter model of the water knife sand tube is 0.76mm, 0.8mm, 1.0mm, 1.2mm, etc., and the mesh number of the corresponding garnet abrasive is also different. 60#, 80#, 120 are commonly used. # The bigger the mesh, the smaller its particle size will be.
How to match the two, usually the smaller the inner diameter of the waterjet sand pipe, the greater the type of garnet abrasive selected, and vice versa. In addition to the model to be determined first, it is necessary to learn how to judge the quality of waterjet garnet abrasives.
e most used consumable for waterjet cutting has a positive effect on improving the cutting quality.
