数显技术是机械工业重点推广应用的新技术之一。 早在七十年代初期,机械工业部就着手组织开发和推广这项新技术。通过十几年的努力,数显技术已在机械工业新产品的开发和老设备的技术改造方面发挥了积极的作用。在国家重点科研项目和国防工程中发挥了重要作用。 在新产品开发方面,如汉川机床厂和昆明机床厂开发的两种数显转台,分度精度均已达到世界先 Digital display technology is one of the key technologies promoted and applied by the mechanical industry. As early as in the early 1970s, the Ministry of Machinery Industry began to organize the development and promotion of this new technology. Through more than ten years of hard work, the digital display technology has played an active role in the development of new products in the machinery industry and in the technological transformation of old equipment. It has played an important role in national key scientific research projects and defense projects. In terms of new product development, such as the two digital rotary tables developed by Hanchuan Machine Tool Plant and Kunming Machine Tool Plant, the division accuracy has reached the world’s first
