These lists demonstrate the basic industries around the world that are served by the special machine tool industry and some of the products that are produced on those machine tools.

The list relates to the actual manufacture of components. It does not cover the automated mechanical assembly or the welding of components to become larger, more comprehensive components. Nor does it include automatic testing, which is many times part of a manufacturing process. Together, they will likely equal the size of the list above.

It is not easy to put this into perspective, but consider the following: In the U.S. alone, in a 15 million-unit car year, the automotive list above represents roughly 750 million complex, precision parts to be manufactured, mostly on special machine tools, in one year. The small engine industry, consisting primarily of lawn mowers, snow blowers, chainsaws, pump and generator sets, etc, would account for a number of a similar magnitude.

Further, most of the components listed require multiple operations, usually meaning multiple machine tools. Many times, as in the case of a cylinder block for an auto engine, they will require many. Fourteen different multi-station machines are normal for the cylinder block, each of which performs many different operations. Similar numbers are required to process a crankshaft. It is also common that two or more lines of production equipment can be required to meet the desired production volume of a given product, doubling those numbers or more.

The components being manufactured are very diverse and range from delicate aluminum pieces, such as pistons and typewriter frames at very high production rates, to gigantic cast iron diesel or welded locomotive cylinder blocks and power generation turbine components at very low production rates.
