伟大领袖毛主席教导我们:“研究任何过程,如果是存在着两个以上矛盾的复杂过程的话,就要用全力找出它的主要矛盾。捉住了这个主要矛盾,一切问题就迎刃而解了。”组合机床通用部件(包括动力部件和支承部件)是组成组合机床的主要部件,而动力部件又是通用部件中最重要的部件。它们都是构成组合机床及其自动线的基础。通用部件,特别是动力部件的发展,将推动组合机床及其自动线的发展和技术水平的提高。因此,要发展组合机床,首先必须发展通用部件尤其是动力部件。这样,才能使组合机 Chairman Mao, the great leader, taught us: "If we look into any process, and if there are complicated processes of more than two contradictions, we shall try our best to find out its major contradictions and seize this major contradiction so that all problems will be solved. The universal parts of the combined machine (including the power and support parts) are the main components that make up the combined machine tool, and the power unit is again the most important part of the common parts. They form the basis of the combined machine and its automatic lines. The development of common parts, especially power parts, will promote the development of modular machine tools and their automatic lines and the improvement of their technical level. Therefore, to develop a combined machine tool, you must first develop common components, especially power components. In this way, to make the combination machine
