| 词条 | Micrometer adjustment nut |
| 释义 | {{Multiple issues|{{Unreferenced|date=November 2015}}{{orphan|date=November 2015}}{{Underlinked|date=January 2017}} }} On a manual milling machine, the micrometer adjustment nut limits the depth to which the cutting tool may plunge into the workpiece. It is located on a threaded rod on the mill head. The machine operator moves it up or down by rotating it clockwise (to move it down) or counter-clockwise (to move it up). Moving the nut down increases the depth to which the cutting tool may plunge into the workpiece. Moving the nut up reduces the depth to which the cutting tool may plunge into the workpiece. 1 : Machine tools |
