The numerical control device of Siemens adopts modular structure design, with good economy. It is equipped with a variety of software on a standard hardware, so that it has a variety of process types, meets the needs of various machine tools, and becomes a series of products. With the development of microelectronic technology, more and more large-scale integrated circuits (LSI), surface mount devices (SMC) and advanced processing technology are used, so the new system has more compact structure, stronger performance and lower price. Simatics series programmable controller or integrated programmable controller is adopted, and syep programming language is used. It has rich man-machine dialogue function and multi language display.
Siemens CNC devices mainly include sinumerik3 / 8 / 810 / 820 / 850 / 880 / 805 / 802 / 840 series.
