A milling machine is a machine tool that is used to machine workpieces by removing material. Milling machines are available in many different sizes and designs and are used in many different industries such as metalworking, plastics manufacturing and woodworking. Essentially, a milling machine consists of a rotating milling head and a stationary workpiece. The workpiece is moved either manually or automatically to move the milling head to the desired position. Most modern milling machines are equipped with CNC controls that allow them to mill complex 3D shapes and contours. There are different types of milling machines, including vertical milling machines, horizontal milling machines, portal milling machines, bed milling machines and universal milling machines. Each type has its own specific advantages and disadvantages and is better suited for certain applications than others. Milling machines are very versatile machine tools and are used in the manufacturing industry for a variety of applications, including the production of tools, the production of molds, the production of prototypes and the mass production of products.
