西德《本茨》汽车公司生产的轿车和2～38吨载重汽车共有650种,其载重车是以几种发动机为基础,通过采用各种不同尺寸的车身,轮距和驾驶室等构成了不同的车型。产品的多样化使得一些零件的加工不能采用大量生产的方式,不得不进行中小批量的生产。中批量生产通常是带有重复性的成批生产。根据西德的情况,这个批量通常为年产500～1000件,按期轮番组织生产。对于这种批量的生产采用什么工艺手段,是机械制造业中需要解决的问题。特别是大批生产通过生产过程的综合自动化提高了生产效率以后,如何提高中小批量生产的效率,问题就更加突出。品种多、批量小、轮番生产等特点对加工设备提出了相应的要求:具有较高的加工效率;具有较大的灵活性,能够方便地适应不同零件的生产;具有能完成多种工艺的性能,以缩短工艺路线。基于这些要求,西德的组合机床行业发展了一些适合于中小批生产的组合机床。
There are 650 cars and 2 to 38-tonne trucks made by the West German “Benz” car company. The truck is based on several engines and is made up of bodies of various sizes, wheelbase and cabs Different models. The diversification of products makes some parts can not be processed in a large number of production methods, had to small and medium-sized production. In mass production is usually a repetitive batch production. According to the case of West Germany, this lot usually produces 500-1000 pieces per annum and organizes production on schedule. For this batch of production using what technology means, is the machinery manufacturing industry to be solved. In particular, mass production through the production process of integrated automation increased production efficiency, how to improve the efficiency of small batch production, the problem becomes even more prominent. Variety, small quantities, turns production and other characteristics of the processing equipment put forward the corresponding requirements: a higher processing efficiency; with greater flexibility, can easily adapt to different parts of the production; has the ability to complete a variety of processes , To shorten the process route. Based on these requirements, the combined machine tool industry in West Germany has developed a number of machine tools suitable for small and medium batch production.
