丝锥折断的主要原因是丝锥和孔不同心。虽然工件材料不均匀也能将丝锥折断,但一般只是使丝锥崩刃。特别是流水线生产时,钻孔和攻丝需两次夹紧,要保证孔和丝锥的良好同心度,很不易。为了提高工作效率和降低废品率,我们根据用户的要求,设计了适用于通孔攻丝的浮动丝锥,使用效果很好,大大降低了丝锥的折断率,现介绍如下: Taps broken main reason is that the tap and hole are not the same heart. Although the workpiece material can also break the taps uneven, but generally only tap collapse. Especially in the assembly line production, drilling and tapping need to be clamped twice. To ensure good concentricity between holes and tap, it is not easy. In order to improve the work efficiency and reduce the rejection rate, we designed a floating tap suitable for through-hole tapping according to the requirements of the user, and the use effect is very good, greatly reducing the break-off rate of the tap, as follows:
