我国目前机床拥有量超过300万台,从数量上看居世界第二位,但突出的矛盾是素质差、性能落后。其中很大一部分必须淘汰更新,还有一部分急需采用新技术进行改造或改装。用微电子技术改造老机床,特别是改遣重型、精密机床,效果很好,这一点己被人们所普遍接受。当前,在积极抓数控改装试点的同时,要着重抓机床的数显改装工作。因为在老机床上安装数显装置,能提高加工精度和质量,减少辅助工时,减轻劳动强度,从而提高机床的加工效率(一般可提高20～30％,对复杂零件可成倍提高),经济效益十分显著。国内生产数显感应同步器的工厂目前只有一家,即上海水平仪厂。该厂生产感应同步器己有多年历史,具有较高的技术水平。本刊发表这篇文章,希望对正在从事老机床改造的读者们有所帮助。
At present, the number of machine tools owned by our country exceeds 3 million sets, ranking second in the world in terms of quantity. However, outstanding contradictions are characterized by poor quality and backward performance. A large part of them must be eliminated and some are urgently needed to be retrofitted or modified with new technologies. Microelectronics technology to transform the old machine, especially to send heavy, precision machine tools, the effect is good, it has been generally accepted. At present, actively grasp the CNC retrofit pilot at the same time, we must focus on the machine’s digital conversion work. Because the old machine installed digital display device, can improve the processing accuracy and quality, reduce the number of auxiliary man hours, reduce labor intensity, thereby enhancing the machine tool processing efficiency (usually can increase 20 ~ 30%, for complex parts can be doubled), economy Benefit is very significant. Domestic production of digital inductive synchronizer factory is currently only one, that is, the Shanghai level instrument factory. The factory production of inductors have many years of history, with high technical level. This article published this article, I hope to be engaged in the transformation of the old machine readers help.
