机械手表中受力较大的部位是条轴上下孔和中心轮轴上下孔,因而这两个部位轴孔的磨损也比较大。但由于大钢轮所处的位置不同,使得这两个孔磨损的方位也不同。手表夹板轴孔磨损方位的判断和修整在机械手表中受力较大的部位是条轴上下孔和二轮轴(中心轮轴)上下孔, Mechanical watch parts of the larger force is up and down the axis of the shaft and the center shaft up and down the hole, so the two parts shaft hole wear is relatively large. However, due to the location of the large steel wheels, making the two holes wear different orientation. Wrist watch plate axis hole to determine the location of wear and repair and mechanical stress in the larger parts of the watch is the upper and lower holes and the shaft axis (center axle) up and down hole,
