一、内螺纹拉削丝锥的结构参数及使用一、拉削丝锥的特点拉削丝锥是一种高效率的内螺纹成形刀具,可以用来加工各种形状的内螺纹。(图1)采用拉削丝锥加工内螺纹有下列优点:1、生产率高:拉削丝锥一次或二次最多三次成形,因此比车加工效率提高4—6倍。加工多头螺纹尤为显著。2、加工精度、光洁度高,质量稳定:拉削丝锥可加工GB785—65—级精度梯形内螺
First, the internal thread broaching tap structural parameters and the use of First, the characteristics of broaching tap Cone tapping is a high efficiency thread forming tool that can be used to process various shapes of the female thread. (Figure 1) The use of broaching tap internal thread has the following advantages: 1, high productivity: pull the tap one or two times up to three times forming, so than the machining efficiency increased 4-6 times. The processing of long thread is particularly significant. 2, processing precision, finish high, stable quality: Broaching tap can be processed GB785-65-level precision trapezoidal thread
