今天讨论的题目,是工具机的传动机构。因为工具机太广泛,所以预备将资料偏重於最普通的车床方面。今天的目的,是将问题提出供大家讨论,因此都是个别的问题,而是没有系统的。 The topic discussed today is the drive mechanism of the power tool. Because the machine tools are too wide, they are prepared to focus their data on the most common lathes. The purpose of today is to ask questions for discussion. Therefore, they are individual questions and they are not systematic.
