What is abrasive belt grinding?
Abrasive belt grinding is a process method in which the moving abrasive belt is brought into contact with the workpiece in a corresponding contact mode according to the shape of the workpiece.

The abrasive belt is mainly composed of three parts: matrix, bond and abrasive.
The substrate is a support for abrasive particles and can be made of paper, cotton cloth, and chemical fiber. Commonly used binders include animal glue, synthetic resin, and a mixture of the two. Commonly used binders include animal glue, synthetic resin, and a mixture of the two. Animal glue has very low heat resistance, low bond strength, and is not eroded by wear-resistant cutting fluid. It can only be used for dry grinding; synthetic resin binder has high bond strength and high wear resistance, suitable for manufacturing high speed Heavy duty abrasive belt. Abrasives used to make abrasive belts are standard electric corundum, white and chromium-containing electric corundum, single crystal electric corundum, aluminum oxide, zirconium dioxide, green and black silicon carbide.
What are the classification methods for abrasive belt grinding?
Belt grinding can be divided into closed belt grinding and open belt grinding according to the grinding method. Abrasive belt grinding can be divided into contact wheel type, support plate type, free contact type and free floating contact type according to the contact form of the belt and the workpiece.
Problems that often occur during abrasive belt grinding: clogging, sticking, and blunt grinding. In addition, the belt often breaks frequently, wear marks and other phenomena during use.
