线轴

High processing accuracy due to superprecision linear motion pair adopted in moving parts.

运部分采用高精度直线轴承运,角精度高。

It required three spools, each containing approximately 900 feet of number 27 Heavy Formvar wire for the primary sections.

这个工作需要个线轴，每个上面有900英尺27号线绕制初级绕。

The three wires were fed from the three spools and wound as one wire; thus comprising the trifilar terminology.

条线从个线轴出绕成一条线，从而线并绕的要求。
