Other and special milling machines refer to a variety of milling machines designed for specific applications or industries that do not fit into the other categories such as universal machines, bed machines, duplex long milling machines, gantry and gantry milling machines, engraving and copying milling machines, crankshaft and camshaft milling machines, finishing machines. Some examples of special and other milling machines can be: Heavy-duty milling machines: are designed for use in harsh environments such as mining or the oil and gas industry, they are particularly stable and robust Waterjet milling machines: are used for cutting hard or abrasive materials such as ceramics or stones, they use a waterjet as a cutting tool 5-axis milling machines: are designed for machining complex geometric shapes, they can work in 5 dimensions Laser milling machines: are used for cutting materials with high precision and speed, they use a laser beam as cutting tool 3D milling machines: are used for prototyping and milling complex geometric shapes in 3 dimensions. These are just a few examples of special and other milling machines, there are many other types of milling machines designed for specific applications or industries. They usually require special training and experience of the operator and are usually more expensive than standard milling machines.
