这里介绍两种取出折断丝锥的方法。图1所示孔里折断的丝锥,螺纹为1M×1.5,最初我们采用四根普通钢丝(较丝锥沟槽约小0.2毫米)装在一扳手上(图2)去取,但扳起来很费力,后来又加一扳手(图3)来取,很快就取出来了。另一种工件如图4所示折断丝锥螺纹为1M12×1.5, Here are two ways to remove the broken tap. The broken tap in the hole shown in Figure 1 has a thread of 1Mx1.5. Initially we used four plain wires (about 0.2mm smaller than the tap groove) on a wrench (Figure 2), but it was very laborious , Then add a wrench (Figure 3) to take, quickly taken out. Another kind of workpiece as shown in Figure 4 broken tap thread 1M12 × 1.5,
