机械加工技术的发展、测试技术的进步,以及经济上和操作上的要求,所有这些既支配机床整体设计概念的变动,也支配着各结构部分具体设计的变化。但是,迄今为止,机床设计者较多地注意结构要素设计的改革,而较少注意整体设计的发展。他们对机床零、部件设计的改革作了不少努力,但机 The development of machining technology, the advancement of testing techniques, and the economic and operational requirements all govern both the changes in the overall design concept of the machine tool and the changes in the specific design of the various components. However, so far, machine tool designers pay more attention to the reform of structural element design, and pay less attention to the development of the overall design. They made a lot of effort on machine tool zero and component design reform, but the machine
