A grinding wheel is a tool used for grinding, which is a type of machining process that uses an abrasive surface to shape or finish materials. Typically made from a composite of coarse particles, the wheel is designed to remove material from a workpiece, such as metal or stone, by abrasion. Grinding wheels come in various shapes and sizes, depending on their intended use, and are commonly found in workshops and manufacturing settings. These wheels are often mounted on machines like bench grinders or surface grinders to enhance precision and efficiency. The choice of grinding wheel depends on factors such as the material being worked on and the desired finish. Proper selection and maintenance of a grinding wheel are essential for achieving optimal performance and safety during operation.
