This paper explores the experimental modal analysis of machine tool structures with rotating spindle. the excitation signal is the pseudo-random binary M series.

本文利用M序列的随机信号进行了机床运转状态下试验模态分析的探索。

We have an on site Tool Room with E. D. M machine facilities, which means reduced downtime and allows for continued production.

我们有现场模具工作室，配备有电火花设备，可连续加工，减少停工时间。

Bearings used in Higher Precision or machine in Tool Spindle applications are normally fitted with either Phenolic Resin (suffix TPA) or machined Solid Brass cages (suffix m).

在更高的精度，或在机床主轴中的应用机使用的轴承通常采用要么酚醛树脂(后缀tpa)的，或加工固体黄铜保持架(后缀m)。
