A grinding machine or grinder is an industrial power tool that uses an abrasive wheel for cutting or removing the m aterial. It is a process of metal cutting by using a rotating abrasive whee l from the surface of the workpiece. Generally, the grinding is finishing operation to show the high surface quality, accuracy of the shape and dimension.
Centerless grinding operation: This type of grinding operation, two grinding wheels are fitted parallel with a 5-10-degree angle which is provided to obtain a longitudinal motion of the workpiece. A cylinder rod is placed between the two-grinding wheel due to the tilted angle.
A mill is a device that breaks solid materials into smaller pieces by grinding, crushing, or cutting. Such comminution is an important unit operation in many processes. There are many different types of mills and many types of materials processed in them. Historically mills were powered by hand (e.g., via a hand crank), working animal (e.g., horse mill), wind (windmill) or water (watermill). Today they are usually powered by electricity.
