3 Overview
Combined angle gauge by the angle ruler, ruler, center gauge, scale seat, sub-dial and other components, the structure shown in Figure 1
Show. Including the base, sub-dial, ruler can form protractor.
Figure 1 Schematic structure
1-center gauge; 2-foot holder; 3-indexing plate; 4-ruler; 5-angle foot;
Combination angle gauge is mainly used for machining, wood processing angle, length, height measurement and centering
Bit and so on.
4 measurement characteristics
4.1 flatness or straightness of each measuring surface
The measuring surface does not allow convex, ruler measuring surface straightness is not greater than 0.02mm, other measuring surface flatness
