There are various styles and specifications of diamond grinding cup wheels to fit for various application requirements. When deciding what kind of diamond cup wheels should be adopted in your application, you should first examine the nature of the job you are going to perform. The ones with big diamond segments can undertake heavy workload such as for grinding concrete and stone, while the ones with sparse diamond segments are often used for epoxy coatings, paints, glues and other surface coatings. Diamond grinding cup wheels can have different diamond grits, different bonds, different diamond hardness and different diamond concentrations to fit different uses. For example, if the concrete to be ground is hard, the bond should be softer, and if the concrete is relatively soft, the bond should be harder. Get more info, Visit this link: https://adiamondabrasives.com/diamond-cup-grinding-wheel/
