我厂使用硬质合金多齿螺纹车刀(下简称刀片)加工汽车半轴套管螺纹,解决了螺纹中径的质量问题(参见《汽车技术》1984,9)。但在半年后,发现加工出的螺纹有外径偏小现象,(用户也有反映)。表1所列为100根套管螺纹外径现场实测数据(要求φ71.95～71.76)。图1是根据表1画出的套管螺纹外径尺寸波动图。从图中看出,螺纹外径的尺寸绝大部分偏小。
I plant the use of carbide multi-tooth thread turning tool (hereinafter referred to as the blade) processing car axle sleeve thread, to solve the quality of the thread diameter (see “Automotive Technology” 1984,9). However, after six months, we found that the machined thread has a small outer diameter, which is also reflected by the user. Table 1 lists the 100 casing thread diameter field measured data (requires φ71.95 ~ 71.76). Figure 1 is drawn according to Table 1 casing thread diameter size fluctuations. Seen from the figure, the outer diameter of the thread most of the smaller size.
