The micro guide rail 6 is pushed by the push rod of the push-pull dynamometer 3. The thrust is controlled by the dial or display of the push-pull dynamometer 3. When the specified thrust is reached, the reading of the dial indicator 8 is observed. At this time, the reading of the dial indicator 8 indicates the deflection size of the micro guide rail 6. If it is within the specified range, it is qualified. If it exceeds the specified range, it is unqualified.
