A spring grinder is a heavy-duty machine used to remove material from the surface of a workpiece. The characteristic of the grinder is the rotating grinding wheel, which is placed on a stationary workpiece. However, there are several 
different types of grinders, each of which works in a different way.

The feature of the bench grinder is that its shape is similar to that of a bench. They usually have two different grinding wheels: one for removing material and the other for finishing. Their grinding wheels are fixed on the top of the 
worktable.

The characteristic of the abrasive belt grinder is the use of an abrasive belt grinder. Like other grinders, they are designed to remove material from the workpiece, thereby making the workpiece smaller, smoother and more ideal. Surface 
grinders are unique because they have adjustable grinding heads.
