摘要 数控技术发展飞速的今天，数控技术在现代制造业发挥越来越重要的作用，数控机床是数控制造业的核心，随着经济的发展，也有了飞跃的发展：体现在新技术的广泛应用和企业效益的明显改善。目前机床行业的消费主流是数控机床。从国内外市场对数控机床的需求来看，以后数控机床市场具有以下特征：一是经济型数控机床是以后的主流产品。二采用新技术，降低成本，提高产品稳定性是企业生存的关键。Abstract Numerical control technology rapid development today, the numerical control technology play more and more important role in modern manufactuiring, numerical control machine tool is the core of the numerical control manufacturing, with the rapid development of international and domestic economy, the machine tool industry has a leap in the development, reflected in the wide application of new technology and enterprise efficiency improved significantly. The machine tool industry mainstream consumption is no machine tools. From domestic and international market demand for CNC machine tools, CNC machine after the market has the following characteristics: one is the economical no machine tool is the mainstream products later. 2 adopt new technology, reduce costs, improve product, stability is the key of enterprise survival. This article mainly introduced the process of CNC milling machine electrical system design. Vertical no milling machining, the electrical system design is particularly important, its content includes system design, vertical machining center part of PLC electrical control system design, selection of servo drive system and electric control system design. This design gives the whole circuit diagram drawing of digital electrical control system, the key part of modular, introduces in detail the function and usuage of the parts. Is divided into 808 d numerical control system design, power distribution circuit, do and at control circuit, servo power circuit, stop control circuit, and artifacts ligheing circuit design, electrical components selection, the choice of servo driver, servo motor, electrical wiring connection and debugging, fault handling common connection. Through this design manual can basically grasp the vertical processing electrical principle of CNC m
