仪器测帽因长期使用,造成测帽工作面磨损,影响仪器的测量精度。下面介绍一种简单易行的仪器测帽工作平面的修理方法。用一把25—50mm的报废外径千分尺,消除其轴向窜动与径向摆动,将活动测杆光杆部分前端磨小至φ6_(-0.015)~0。把待修平面测帽套在上面进行研磨,方法与修理外径千分尺平面平行性一样,外径千分尺夹持在虎钳上,研磨器 Instrument cap due to long-term use, resulting in measuring cap face wear, affect the measurement accuracy of the instrument. The following describes a simple and easy measuring instrument cap working plane repair methods. With a 25-50mm scrapped outer diameter micrometer, to eliminate the axial and radial swing movement, the rod rod part of the active rod mill small grinding down to φ6 _ (- 0.015) ~ 0. The flat to be repaired measuring cap set in the above grinding, method and repair diameter micrometer plane parallelism, the outer diameter micrometer clamp on the vise, grinder
