Grinding is a process of removing material from a workpiece using a grinding wheel or abrasive belt. This process can be used for finishing, sharpening, and smoothing the surface of various materials. Grinding is commonly used in manufacturing processes such as metalworking, woodworking, and ceramics. There are different types of grinding methods available, including surface grinding, cylindrical grinding, and centerless grinding. These methods can be used for precision grinding, rough grinding, and other applications depending on the material being worked on and the desired outcome.
