The generation of machine tool spindle vibration is becoming prevalent as high-speed machining and lightweight design are being actively applied in the machining process. As the required machining accuracy increases, the machine tool spindle vibration generated in ultra-precision machining is the main cause of the deterioration of the machining quality. In this study, a TiC-SKH51 metal-matrix composite was used to suppress the machine tool spindle vibration. A vibration characteristic test was conducted to obtain the dynamic characteristics of the TiC-SKH51 and other testing materials. By comparing the results of the vibration characteristic test, the reliability of the finite element analysis software was confirmed. Then, dynamic and static analyses were performed to obtain the dynamic and static characteristics of the machine tool spindle model. The analysis results show that the TiC-SKH51 machine tool spindle can directly suppress the generation of spindle vibrations.

随着高速加工和轻量化设计在加工过程中得到积极应用，机床主轴振动的产生越来越普遍。随着所需加工精度的提高，超精密加工中产生的机床主轴振动是导致加工质量下降的主要原因。在这项研究中，TiC-SKH51 金属基复合材料用于抑制机床主轴振动。进行了振动特性测试，以获得 TiC-SKH51 和其他测试材料的动态特性。通过对振动特性试验结果的对比，验证了有限元分析软件的可靠性。然后进行动静分析，得到机床主轴模型的动静特性。
