摘　要
机械工业的生产水平是一个国家现代化建设水平的主要标志之一。而总体看来我国的生产力水平较低，技术不发达。机械装备加工精度和范围都与发达国家有很大差距。我国有一大批设备与现代技术的要求相比都显得太老化，而加工范围也没法达到。怎样在节约成本的基础上尽可能的提高现有设备的利用率，成为制约我国工业水平的一个重要问题。在这个技术前提下，机器改装技术成为了解决这个问题的一个有效的方法。
随着科学技术的发展，即使原来属于先进的机床也会变得陈旧、落后，满足不了产品种类日益增加和质量不断提高的需要，因此有必要以现有的机床为基础，对机床的使用工艺和装备进行革新，对机床的现有结构进行改装。这样既可以使现有机床的加工能力得以提高，同时又能节约新机床设计研发时间，可以得到许多意想不到得效果。
在对机床的现有结构进行改装,对机床的使用工艺和装备进行革新的过程中,并不是一味的追求先进,而应该力争改装方案合理,结构简单巧妙,经济效果好.
这样因地制宜的巧改机床,不仅造价低,上马快,是弥补设备不足和不配套的好办法,也是解决设备“技术老化”问题的重要途径.

Abstract
The mechanical industry production level is one of national modernization level main symbols. But the overall looked like our country the productive forces level is lower, the technology is not developed. The machinery equipment processing precision and the scope all have the very big disparity with the developed country. Our country has large quantities of equipment and the modern technologies request compares all appears too gets older, but processes the scope also to have no way to achieve. How in saves the cost in the foundation the as far as possible enhancement existing equipment use factor, becomes restricts our country industry level unimportant question. Under this technical premise, the machine equipped the technology to become has solved a question effective method.
Along with science and technology development, even if originally belongs to the advanced engine bed also to be able to change absolutely, is backward, could not satisfy the product type can crease the need day by day which and the quality unceasingly enhanced, therefore had the necessity take the existing engine bed as the foundation, carried on the innovation to the engine bed use crafted the equipment, carried on the equipment to the engine bed existing structure. Like this both may enable the existing engine bed the processing ability to enhance, simultaneously and can save the new engine bed design research and development time, may obtain many unexpected effect.
In carries on the  equipment to the engine bed existing structure carries on the innovation to the engine bed use craft and the equipment in the process, certainly is not the constantly pursue  advanced, but should argue vigorously the equipment plan reasonably structure simple ingenious, the economic effect is good .
 Key words：equipment ，  change，  Technical aging
