我厂从1987年开始对进口带锯床进行消化吸收,在自己没有样机的情况下,比照样本设计,开发出GZ4040自动卧式金属带锯床,当年制成三台样机,1988年4月通过大连市科委组织的科技成果鉴定。接着安排小批量生产,1988、1989两年生产出15台,在国内销售。1990年继续生产15台,其中有7台销往国外,直接创外汇6万美元,新增产值140万元,新增利税56万元,替代进口,还为国家节约了大量外汇。几年来,我们在进口带锯床的消化吸收过程中,不断探索,大胆尝试,积累了一些有益于今后工作的经验和体会。 一、选定消化吸收的样机,把好规划选型关 国外带锯床的技术水平发展很快,目前国内进口的一些带锯床分别来自美国、法国和日本等许多厂家,规格有250mm、400mm和1000mm等,样式有立式和卧式之分,卧式中又有锯架采用立柱升降式、锯架摆动式、锯架倾斜式和直立式的差别。选择谁家生产、何 Our factory began to digest and absorb the imported band sawing machine from 1987. In the absence of a prototype, the GZ4040 automatic horizontal metal band sawing machine was developed. At that time, three prototypes were made and passed through Dalian in April 1988. Scientific and technological achievements appraisal organized by the Science and Technology Commission. Subsequently, small batch production was arranged. In 1988 and 1989, 15 units were produced and sold in China. In 1990, it continued to produce 15 units, including 7 units sold abroad, directly creating foreign exchange of US$60,000, adding output value of 1.4 million yuan, adding profits and taxes of 560,000 yuan, replacing imports, and saving a lot of foreign exchange for the country. Over the past few years, we have continuously explored and boldly tried to import the band sawing machine, and have accumulated some experience and experience that will benefit our future work. First, the selected digestion and absorption prototype, the development of a good planning and selection of foreign band sawing the rapid development of the level of technology, the current domestic imports of some band sawing machines from the United States, France and Japan and many other manufacturers, specifications are 250mm, 400mm and 1000mm For example, there are vertical and horizontal styles, and in the horizontal type, the saw frame adopts the difference of the column lifting type, the saw frame swing type, the saw frame tilt type and the vertical type.
