目前,已为大多数通用机床制定了刚度特性,并使其标准化。但是,组合机床及其自动线的动力头和动力滑台尚缺少这方面的数据。明斯克机械科学实验研究所对动力头和动力滑台在运转条件下所进行的统计调查,以及在此基础上对导轨磨损所进行的理论计 At present, stiffness characteristics have been developed and standardized for most general-purpose machine tools. However, the combination of machine tools and automatic line power head and power slide still lack of data in this regard. Minsk Mechanical Science Experimental Research Institute of power head and power slide in the operation under the conditions of the survey, as well as on the basis of the theory of rail wear and tear carried out
