Although today's electronic information industry is rapidly developing, it cannot completely replace machinery. After all, the real working components are the moving mechanism or supporting structure. Most of the parts of these mechanisms directly or indirectly require machine tools to process and form, the control unit is added to become a finished product for consumers, which covers not only the automobile industry for daily use, but high-tech defense/aviation industry, but also production molds for plastic and glass products, production equipment for electronic components, etc. Over the years, in Germany and Japan, the total share of machine tool output value is nearly 50%.
Machine tools are divided into two categories according to their processing patterns. One is "cutting machine tools" that remove material and form a square. Including comprehensive processing machines, lathes, grinders, electrical discharge machines, drilling machines, milling machines, boring machines, sawing machines, planers, gear cutting machines, etc. The other type is a forming tool machine that deforms or truncates materials by applying shear pressure, Including a punching machine, shearing machine, forging machine, punching machine, wire processing machine, etc. In terms of market share of output value, in different countries in the world, generally speaking, cutting tool machines account for about 75%, and forming tool machines account for about 25%. If it is distinguished by the control method, the use of digital signals and computer operations to control the machine tool is a computer numerical control machine tool (CNC machine tool). Otherwise, it is a non-NC machine tool or a traditional machine tool.

Industry evolution history:
The evolution of machine tool industry technology:
Before 1970, Taiwan's machine tool technology still lacked industrial standards and quality control. The performance of the products was low, the quality was also unstable, and the products were limited to traditional machine tools. Later, due to the government's support for a series of precision machine tool development plans, technical cooperation with well-known foreign machine tool factories, and sending personnel to foreign countries for training, as well as the research and development of some large domestic manufacturers, the independent design ability of Yannei gradually established. In addition, manufacturing technology, precision transmission system design and manufacturing, numerical control application and maintenance, precision testing, quality assurance system and other technologies have made great progress. Before 1980, some Taiwanese manufacturers successfully launched CNC lathes, CNC milling machines, CNC integrated processing machines, and CNC grinding machines.
Since 1980, the technology of standard general-purpose CNC machine tools has gradually matured. In addition, third-world countries and China have become more common in traditional machine tools, resulting in a decline in selling prices and compression of profits and living space, making Taiwan's domestic machine tools NC gradually increase. The Mechanics Institute of the French Industrial Research Institute is also making every effort to pave the way for the research and development of machine tools, including inclined bed CNC lathes, horizontal, vertical, five-sided, door-type comprehensive processing machines, and external, internal, and plane CNC grinding machines.
