对游标卡尺作简易的改进,不仅能加快操作速度,而且测得的精度也 高。改进方法是定出两个沉孔,沉孔可在卡尺上 对分规测得的任意尺寸进行调节(图中“A”的尺 寸有一个下限。) 卡尺上的基准孔是用带有微调刻度盘的铣 床或其它机床定位,并用装有锥形金刚石的中 Easy to make vernier caliper, not only to speed up the operation, but also measured the high precision. The improvement is to set two counterbores, counterbore can be adjusted on the caliper of any size sub-regulation (“A” in the figure there is a lower limit.) Caliper reference hole is calibrated with a fine scale Plate milling machine or other machine tool positioning, and equipped with a tapered diamond
