主轴回转系统的径向、轴向运动误差,对工件的加工精度和表面粗糙度有直接影响,它是机床重要动态指标之一。机床主轴的径向、轴向运动误差与各种静态和动态因素有直接关系,它主要决定于轴承和主轴等零件所组成的回转系统的制造质量和装配质量,因此有必要研究探讨主轴回转系统的振动特性对加工零件的影响关系,在这方面我们进行了多年的现场实际测试工作,并取得了一定的经验成果,本文仅对T760双面金刚镗床镗头修理中的动态测试和判别,以及对于轴瓦的加工质量影响进行探讨。
The radial and axial movement errors of the spindle rotation system have a direct impact on the machining accuracy and surface roughness of the workpiece, which is one of the important dynamic indexes of the machine tool. The radial and axial movement errors of the spindle of the machine tool are directly related to various static and dynamic factors. It mainly depends on the manufacturing quality and the assembly quality of the rotating system composed of the bearing and the spindle. Therefore, it is necessary to study and discuss the spindle rotation system Of the vibration characteristics of the relationship between the processing of parts, in this regard, we conducted many years of field actual test work, and has made some empirical results, this article only T760 boring head double boring machine repair in the dynamic testing and identification, and The bearing quality of the impact of processing to be explored.
