大家知道,用以测量线值尺寸的通用量具其测量面的边缘必须倒棱(磨钝),否则会由于边缘的尖棱在测量或检定时损伤波测表面或由于棱边的毛刺使测量结果不准确。通常测量面边缘倒棱面的光洁度不应低于该量具测量面的光洁度,因此,如何保证量具修理后倒棱面的光洁度也是很需要解决的一个问题。 It is known that the universal gauge used to measure the size of a line must be chamfered (blunt) at the edges of the measuring face, otherwise the measuring result may be impaired by the sharp edges of the edge at the time of measurement or test, or by the burrs on the edges Inaccurate. Generally, the smoothness of the chamfered surface at the edge of the measuring surface should not be lower than the finish of the measuring surface of the measuring gauge. Therefore, how to ensure the smoothness of the chamfered surface after measuring is also a problem that needs to be solved.
