光面量规是一种无刻线的专用量具。如塞规、卡规、高度规、深度规和样板等,均以通端(T)和止端(Z)控制零件的尺寸和几何位置偏差,使其不超出最大或最小极限尺寸。所以,这类量规又叫极限量规。目前,国内对这类量规较普遍地实行“班检”、“批检”和“周期检定”,并以蜡封等方法为合格标志。 Smooth gauge is a non-engraved special measuring tools. Such as plug gauges, gauge gauges, gauge gauges, depth gauge gauges, and so on, control the dimensional and geometric misalignments of parts with through ends (T) and stop ends (Z) so that they do not exceed the maximum or minimum limit dimensions. Therefore, this type of gauge is also called limit gauge. At present, the domestic implementation of such measures more generally “class inspection”, “batch inspection” and “cycle test”, and wax seal and other methods as a mark of conformity.
