千分尺是机械工业中常用的最重要的量具之一 ,它分为外径千分尺、内径千分尺和深度千分尺。它可以对零件的外径、球径、内径、长义以及两平面的平行度等内容进行测量。千分尺的工作原理是应用测微螺旋副将微小直线位移转变为便于目视的角位移 ,因为它的设计符合阿贝原理 ,所以
Micrometer is one of the most important measuring tools commonly used in the machinery industry. It is divided into outer diameter micrometer, inner diameter micrometer and depth micrometer. It can be part of the outer diameter, diameter, diameter, length and the two plane parallelism and other content measurements. Micrometer micrometer work principle is the application of micro linear helix will be transformed into a small linear displacement of the visual angular displacement, because it is designed to Abbe principle, so
