What is the prototype attack?

In the prototype industry, the process of tapping teeth is often heard. The so-called tapping is that after the prototype model is processed, if you need to enter the screw on the prototype, you need to make a screw hole in the prototype and then hit the screw again. The process of punching is to attack the teeth. After the teeth are attacked, the screws can be placed.

1 How much is the diameter of the inner hole first calculated?

2 insert the screw attack into the work hole, and the back end is supported with a dead top.

3 The screw wrench must prevent rotation, so it must be stuck in the knife seat (The front has turned at this time)

4 cutting agents should be added frequently (Mainly oil)

5 when attacking teeth on the Zhuo bed, the rotation number of the spindle is at low speed.

6 while the work object is turning, do not break away from the screw attack

7 when the tapping machine is tapping the teeth, turn the tail hand wheel, keep the proper pressure, if loose, will break the screw attack, so pay special attention.
