全生命周期下的机床清洁度

Cleanliness of machine tool in its whole life cycleMA Jialu，LONG Xingyuan(Shaanxi Qinchuan Machine Tool&Group Co.，Ltd.，Bali 721009，CHN)Abstrac：At the critical moment while China machine tool industry is growing from a great nation to a powerful na-tion，it is necessary to make an application of extending the cleanliness into its whole life cycle of ma-chine tools，not only manufacturing but also working.It should also be known that cleanliness is a built- in atribute of machine tools.In this paper，the author describes the concept and classification of clean-liness and its inspection，the methods for geting cleanliness in diferent steps，as well as cleaning andprotecting.In addition，several important concepts of machine tool cleaning and the importance of dust-prooving and sealing in machine tool design are also discussed。

木盆理论可以引导出两个推论：推论 1：如果木盆的-块木板被虫蛀出-个/J，TL，水就会从这个凶中慢慢流走，盛水高度降低，不管这块木板的宽度、高度，也不管它的材质，甚至品牌；推论2：木盆存放环境不适宜或者保养不 良，木板收缩，木板问缝隙不再密合，水会全部流光，甚至木盆散架，不管木盆原先多么精良。
