采用电子技术对旧机床(主要指技术老化落后,不能满足生产要求的机床)进行改造是提高设备精度和效率,优化设备结构,促进设备资源有效利用,使我国经济增长从粗放型向集约型转变的重要途径之一,而且由于技术的不断进步,机床改造也是个永恒的主题。 自70年代开始,我国机械制造能完全满足这些要求。因为任何新设备若干年后也要变成陈旧落后的,故他们必须在更新某些老设备的同时,采用电子技术来改造那些还有使用价值的旧机床。因为电子技术发展最快,其对机床的性能质量和结构改进的影响最大,同时也是使许多传统的旧机床提高加工精度、效率、自动化程度和重新焕发青春的最有效的技术。正因为如此,人员素质低之外,我国拥有的机床技术比较陈旧落后,特别是数控、高效和自动化机床的占有率低,不能不说是一个很重要的原因。例如,据1989年的统计数据,美国拥有金切机床1870753台,其中役龄少于10年的占40％,数控机床占10.9％,高效自动和半自动机床占60％以上;1994年日本公布的统计 The use of electronic technology to retrofit old machine tools (mainly referring to technology aging and failing to meet production requirements) is to improve equipment accuracy and efficiency, optimize equipment structure, and promote the effective use of equipment resources, so that China’s economic growth shifts from extensive to intensive. One of the important ways, and because of the continuous advancement of technology, machine tool rebuilding is also an eternal theme. Since the 1970s, China’s machinery manufacturing can fully meet these requirements. Since any new equipment will also become obsolete after a few years, they must use electronic technology to renovate old machines that still have value in use while updating certain old equipment. Because of the fastest development of electronic technology, it has the greatest impact on the performance, quality and structural improvement of machine tools, and it is also the most effective technology that enables many traditional old machine tools to improve machining accuracy, efficiency, automation, and rejuvenation. Because of this, the low quality of personnel, China’s own machine tool technology is obsolete, especially the numerical, efficient and automated machine tool’s low share, it can not be said to be an important reason. For example, according to the 1989 statistics, the United States has 1,807,753 gold-cutting machine tools, of which 40% are less than 10 years old, 10.9% are CNC machine tools, and more than 60% are high-efficiency automatic and semi-automatic machine tools; they were released in 1994 in Japan. statistics
