Although the pure water jet (without abrasives) can cut softer materials, such as foam and rubber, adding abrasives will enhance the cutting ability of the jet to cut glass. , Steel and various other parts. And as you might imagine, the type of abrasive used is very important to determine the processing effect
Professionals have tested various synthetic and natural materials for water jet cutting, and the outstanding choice in the industry is garnet. The sharp edges formed when the garnet abrasive breaks provide superior cutting ability. Garnet has excellent characteristics of filling, density and particle shape to improve cutting ability.
According to Mohs hardness, the hardness of diamond is 10 (the hardest substance known), while the hardness of garnet is usually between 7.5 and 8.0. There are even stronger mineral choices, and garnets usually provide the best hardness at the most reasonable price. As an abrasive substance, the advantages of garnet are:
Significant hardness. Garnet can usually be used continuously before it needs to be replaced, becoming a cost-effective abrasive.
Garnets come in a variety of particle sizes and are expected to provide different results, such as smooth or rough surfaces, and the hardness of the material being processed. In most cases, companies need to use finer abrasive grains for processes that require higher edge quality, and for projects that require shorter cuts, larger abrasive grains are most effective
