Milling covers a wide variety of different operations and machines, from small individual parts to large, heavy-duty group milling operations. It is one of the most widely used processes of machining custom parts with precise tolerances. Milling can be done in different directions on one or more axes, cutting head speed and pressure.

milling head and milling machine spindle are properly adjusted vertically for operation. The plain vertical machines are characterized by a spindle located vertically, parallel to the column face, and mounted in a sliding head that can be fed up and down by hand or

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.
