修理300mm以上千分尺平面度、平行度时,可将其安置在JGA激光千分尺平行度检查仪上进行。在检修中,笔者有以下两点体会: 1.在检修几把类型相同的外径千分尺时,可将其中一把尺的弓架装在仪器上,然后装上其余各尺的测微杆,按步骤修理好平面度和垂直度。在仪器上以修好的测微杆测量面为基准,检修测砧测量面。这样可减少装拆研磨 Repair more than 300mm micrometer flatness, parallelism, it can be placed in the JGA laser micrometer parallelism tester. In the overhaul, I have the following two points of experience: 1. In the maintenance of several types of the same outer diameter micrometer, one of the scales can be mounted on the archer of the instrument, and then loaded with the rest of the ruler micrometer rod, Follow the steps to repair the flatness and verticality. On the instrument to repair the micrometer rod measurement surface as a benchmark, maintenance anvil measurement surface. This will reduce the loading and unloading grinding
