一二二厂技改办工艺试验室最近在网状砂毡的研制工作中,取得成果。制成一批试验砂毡,为发展砂毡技术迈出了重要的一步。砂毡是美国六十年代出现的,用于零件抛光的新产品。由于在抛光加工方面的明显优越性,砂毡技术很快在一些主要的资本主义国家发展起来。到七十年代初期,日本已建立了专门的砂毡生产线,英国则成立了专门的砂毡生产工厂,产品供全国使用。我厂目前试制的砂毡,就是仿照一九七二年从英国带回的一块样 One two two factory technical transformation to do the Technology Laboratory Recently in the mesh sand felt research and development work and achieved results. Making a group of test sand felt, for the development of sand felt technology has taken an important step. Sand felt is the United States appeared in the 1960s, new parts for polishing. Sand felt technology soon developed in some of the major capitalist countries due to the obvious superiority in polishing. By the early 1970s, Japan had established a special sand-mat production line and the United Kingdom set up a special sand-mat production plant for use throughout the country. At present, the trial production of sand mats in our factory is just like a sample brought back from Britain in 1972
