一、底座工作面的修理修理高度游标卡尺的底座工作面时,用双手压住底座四角,然后在长研磨平板上来回研磨,研磨时间可以长些,以加快研磨修理。在底座研磨时,可经常调换方向,这样能保证底座的平直性,修理后的底座工作面允许在1mm范围内塌边。同时,在研磨中可根据损坏程度选用不同的研磨膏,精磨一般可采用W28钢玉粉(金刚砂),细磨一般可采用W5研磨膏,待研磨后可把研磨膏揩去,再进行来回几次的干研,不必太长时间,在工作面上就能达到光洁度要求。二、划线量爪工作面的修理
First, the working surface of the base repair vernier caliper when the base surface, with both hands hold down the corners of the base, and then grind back and forth on the long grinding plate, grinding time can be longer to speed up grinding and repair. Grinding in the base, you can always change direction, so that the base can ensure the straightness, the base surface after repair allows the collapse of the edge in the range of 1mm. At the same time, grinding can be selected according to the extent of the damage of different grinding paste, grinding generally can be used W28 steel jade (emery), fine grinding generally can be used W5 grinding paste, grinding can be grinding paste 揩 go, and then back and forth Several times to do research, do not have too long time, can meet the finish requirements on the work surface. Second, crossed the claw face of the repair
