在第一小五年计划初期，我国各机床制造厂命名的机床型号，多系采用外国的命名方法，有的是用苏联的，有的是用德国的，也有的是用英、美的，五光十色很不统一；在工作上造成了许多不便。为了改善这种情况，曾在１９５６年施行了全国统一的编制型号的方法，自施行以来，对统一型号起了一定作用。但它在使用上却也产生了很多不便，最主要的毛病是没有根据我国实际情况，而只是生硬地搬用了外国的办法，致使型号与机床的特征不能紧密的联系起来，造成了规定型号与与实际使用不相一致。几年来很多同志提出了不少意见，要求更改编制方法，以求通俗易懂，便于使用，能被广大群众所接受，为此金属切削机床研究所，根据各方面的意见；提出了这份建议书。为使这一工作进行的更有群众性，我们特地把它选登在这里，希望广大读者踊跃提出意见。
In the early stage of the first small five-year plan, the machine tool models named by China’s machine tool manufacturers were mostly based on foreign naming methods. Some of them were used in the Soviet Union, some were in Germany, and some were in Britain and the United States. The colors were not uniform; There are many inconveniences in the work. In order to improve this situation, in 1956, a nationwide unified method for the preparation of models was implemented. Since its implementation, it has played a role in the unified model. However, it has also caused a lot of inconvenience in its use. The main problem is not based on the actual situation in China, but it is simply a method of using foreign countries rigorously, resulting in the model and machine tool characteristics can not be closely linked, resulting in the specified model and Not consistent with actual use. Over the past few years, many comrades have put forward many opinions and requested to change the method of preparation so as to be easy to understand, easy to use, and accepted by the masses. The Institute of Metal Cutting Machine Tools, based on opinions of various parties, proposed this proposal. book. In order to make this work more mass-producing, we have specially selected it here, and hope that the readers will enthusiastically put forward their opinions.
