The invention relates to an anchor rod centering degree experiment device and method based on a numerical control drilling machine. The anchor rod centering degree experiment device based on the numerical control drilling machine comprises an anchor rod centering degree adjusting structure, a similar anchoring hole fixing structure and a workbench connection fixing structure, and the anchor rod centering degree adjusting structure comprises anchor rod centering degree control components. The anchor rod centering degree control components with different centering degrees are machined by adjusting the positions of anchor rod limiting holes, so that a plurality of anchor rod experiment test pieces with preset centering degrees are accurately screened out, accurate control over the anchor rod centering degree in the experiment process is achieved, and the experiment effect is guaranteed; and according to the experimental method adopting the device, accurate control over the anchor rod centering degree can be achi
