A grinding machine or grinder is an industrial power tool that uses an abrasive wheel for cutting or removing the material. It is a process of metal cutting by using a rotating abrasive wheel from the surface of the workpiece. Generally, the grinding is finishing operation to show the high surface quality, accuracy of the shape and dimension.
Milling Machine Definition: The milling machine is a type of machine which removes the material from the workpiece by feeding the work past a rotating multipoint cutter.The metal removal rate is higher very high as the cutter has a high speed and many cutting edges. It is the most important machine in the tool room as nearly all the …
