Abstract: A rolling device and a measuring device are disclosed. A rolling assembly in the rolling device is movably mounted on a bracket in a first direction (a) parallel to a working surface, and when a member to be rolled is placed on the working surface, the rolling assembly provides a rolling pressure to the member to be rolled. In a rolling process, the rolling assembly moves in the first direction (a), so as to be capable of ensuring that the rolling pressure applied to the member to be rolled is constant and always perpendicular to the member to be rolled, that is, ensuring that the rolling pressure remains constant, thereby reducing the influence of external factors on the rolling process and improving the accuracy of a measurement result.
