極限量規(又叫驗規),是一種在大量生產中用來檢驗成品尺寸的量具;一般分成測量軸用的卡規和测量孔用的塞規兩大類。因為它是作成固定形狀的,所以使用起來比較方便,也比普通量具(如卡钳、游標卡尺等)的度量來得可靠,同時遺可以節省测量的時間。目前一般工廠的產品都逐漸地走向專一化,而量規的應用就更加普遍、更加重要了。並且量規是一
Limit gauge (also known as inspection rules), is used in a large number of production to test the size of the finished measuring instruments; generally divided into the measuring shaft with the gauge and gauge hole gauge two categories. Because it is made into a fixed shape, it is more convenient to use and is more reliable than conventional gauges (such as calipers, vernier calipers, etc.), saving you time. At present, the general factory’s products are gradually becoming specialized, and the application of the gauge is more common and even more important. And the gauge is one
