金属切削机床是机器制造工业的主要技术设备。在机械工业中,若以台数计算,一般约有60～80%是机床。机床的拥有量也是衡量一个国家的工业生产能力的重要标志之一。机械制造工业按其生产性质可以分为单件小批生产、中批生产和大批大量生产;按照加工零件的大小可以分成重型、中型和小型等。各种生产性质和类型对机床的要求是不同的。现在生产所使用的机床都存在一定的缺陷和矛盾。例如:重型零件的机械加工,一般是单件小批生产,而现在所用的重型通用机床不但生产周期很长,设备成本很高,而
Metal cutting machine tool is the main technical equipment manufacturing industry. In the machinery industry, if the number of units, usually about 60 to 80% of machine tools. The possession of machine tools is also one of the most important symbols to measure the industrial productivity of a country. Machinery manufacturing industry according to their nature of production can be divided into single small batch production, batch production and mass mass production; according to the size of processing parts can be divided into heavy, medium and small and so on. The requirements for the machine are different for the nature and type of production. Now the machine tools used in production have certain defects and contradictions. For example: heavy parts machining, usually a single small batch production, and now used in heavy universal machine not only the production cycle is very long, high equipment costs, and
