用跳牙丝锥攻丝有下列优点:切削抗力小,排屑特别容易,故此加工成的螺孔表面粗糙度较高,跳牙丝锥的使用寿命较一般丝锥要长得多。一、偶数槽跳牙丝锥中径的测量当我们想测量偶数槽跳牙丝锥的中径时,确定三针直径和 M 值有作图法和计算法两种。
Tapping with tap tap tapping has the following advantages: cutting resistance is small, particularly easy chip removal, so processed into a higher degree of surface roughness screw tap tap tap life is much longer than the average tap. First, the even slot hopper tap diameter measurement When we want to measure the even slot hopper tap diameter, determine the three-pin diameter and M values are plotting and calculation of two.
