3 Overview

Integral inside micrometer to measure the inside diameter of the main workpiece can also be used to measure the distance between the two inner surfaces from. Integral inside micrometer consists of four parts, including micrometer head portion, Take pole portion (2m or 6m inner diameter Micrometer access pole), the base portion and a foot-foot tail section. Its shape and structure shown in Figure 1. Figure 1 Integral micrometer diameter schematic 1- micrometer; 2- Take pole;-foot-3-yl; 4 - anchor; 5- foot tail section

4 Metrological characteristics

The radius of curvature of 4.1 probe Face Integral radius of curvature inside micrometer probe face, should not exceed 100mm. Surface roughness of 4.2 Face Two head face surface roughness measurement should not exceed Ra0.4μm; within the measuring rod end faces of each table access pole The surface roughness of not more than Ra0.2μm. 4.3 groove width and width difference Fixed casing vertical engraved lines and line width of the differential cylinder (0.15 ~ 0.25) mm, groove width should not exceed the difference Over 0.05mm.
