Technical Field

[0001] This utility model relates to the field of grinding wheel technology, and in particular to a grinding wheel mounting structure with easily replaceable grinding wheel layers. Background Technology

[0002] Grinding wheels are the most important type of abrasive tool in grinding processes. A grinding wheel is a porous material made by adding a bonding agent to abrasive grains, followed by pressing, drying, and firing. Due to differences in abrasive grains, bonding agents, and manufacturing processes, the properties of grinding wheels vary greatly, thus significantly impacting the processing quality, productivity, and economy of grinding. Grinding wheels are also known as bonded abrasives; they are formed by bonding ordinary abrasive grains into a specific shape and giving them a certain strength. After prolonged use and significant wear, the grinding wheel layers need to be replaced. Therefore, a grinding wheel mounting structure that allows for easy replacement of the grinding wheel layers is required. Utility Model Content
