本文件提供了如何评估主轴壳体上测量的机床主轴振动严重程度的信息。它为评估在客户现场或机床制造商测试设施的主轴壳上测得的振动严重性提供了具体指导。 其振动标准适用于额定运行速度在600 r/min和12000 r/min之间的固定式机床用齿轮驱动主轴。 它仅适用于滚动轴承类型的主轴，适用于组装在金属切削机床上的主轴，并用于测试、定期验证和连续监测。 它不涉及: -旋转轴的几何精度（见ISO 230-7）； -表面光洁度和精度方面的切割性能不合格； -机床主轴以低于600 r/min或超过12000 r/min的速度运行时的振动严重性问题（由于缺乏支持振动数据）；或 -频域分析，如快速傅立叶变换（FFT）分析、包络分析或其他类似技术。 附录A介绍了替代轴承状态评估技术。

This document provides information on how to assess the severity of machine tool spindle vibrations measured on the spindle housing. It gives specific guidance for assessing the severity of vibration measured on the spindle housing at customer sites or at the machine tool manufacturer's test facilities. Its vibration criteria apply to gear-driven spindles intended for stationary machine tools with nominal operating speeds between 600 r/min and 12 000 r/min. It is applicable to those spindles of the rolling bearing types only, to spindles assembled on metal cutting machine tools, and for testing, periodic verification, and continuous monitoring. It does not address: — geometrical accuracy of axes of rotation (see ISO 230？7); — unacceptable cutting performance with regards to surface finish and accuracy; — vibration severity issues of machine tool spindles operating at speeds below 600 r/min or exceeding 12 000 r/min (due to lack of supporting vibration data); or — frequency domain analyses such as fast Fourier transform (FFT) analyses, envelope analyses or other similar techniques. Annex A presents an introduction to alternative bearing condition assessment techniques.
