一、数控机床及配套的市场概况 1 .发展数控机床的重大意义 数控机床是国家工业现代化的重要标志。数控机床是数控技术与机械加工工艺相结合产生出的新一代机械制造技术装备。它的出现使传统机械加工实现了质的飞跃:可实现钻、镗、车、磨等工序集中加工,从而提高工效3～5倍,精度可达μ级;可实现各种复杂形状,包括立体曲面的自动化加工,如五轴联动加工
First, the market overview of CNC machine tools and supporting 1. The significance of the development of CNC machine tools CNC machine tools is an important symbol of national industrial modernization. CNC machine tools are a new generation of mechanical manufacturing technology and equipment that are produced through the combination of numerical control technology and mechanical processing technology. Its appearance has enabled the traditional mechanical processing to achieve a qualitative leap: it can achieve centralized processing of drilling, boring, turning, grinding and other processes, thereby improving the work efficiency 3 to 5 times, the accuracy can reach μ level; can achieve a variety of complex shapes, including three-dimensional Automatic surface machining, such as five-axis machining
