The following is a detailed description of baby:
Screw special aluminum in the attack on the aluminum tapping, because of the particularity of aluminum (soft and sticky knife, not easy to cause chip taps of blocked chips wear broken taps) aluminum chip its relatively ordinary spiral screw is reduced to two, and deepen in cutting aluminum material continuously. From the cutting effect is good. Because about 35 degrees of the right wing groove cutting can be discharged from the hole, cutting speed can be higher than the straight groove wire attack 30%-50%, compared with ordinary wire attack because of its chip groove deeper and wider, so it is not easy to chip, wire attack is not easy to break. Secondly, aluminum special wire tapping effective tooth length reduced to ordinary tap 1/3, deep hole machining is also very effective.
