3 Overview
A flat ruler is a gage that has a flat working surface and is used to measure the straightness and flatness of the surface of the workpiece. Flatness accuracy, etc.
The levels are 00, 0, 1, and 2.
Flat structure.
The cast iron flat rule structure is shown in Figure 1;
Figure 1 Cast iron flat rule structure diagram
The structural forms of steel flat feet and rock flat feet are shown in Figures 2 and 3.
Note. As a calibration, if it is not qualified or not, if the accuracy level is to be determined, the corresponding requirements must be met.
