The following tells you how to deal with the most common problem of holes not being punched out.
Then there is a cover plate on the back of the punching machine with four screws on it.
The first step is when the hole is not punched through, and also when the punching tool is not pressed deep enough. First open the cover plate.
After opening it, turn off the air pressure of the punching machine and let the air pressure out.
Then go back inside the machine and there is a nut above the head which needs to be loosened with a spanner.
The reason why the punch does not go through is probably because the punch is too shallow, so adjust the lower punch to a deeper depth.
There is a disc with a number of notches on it, which makes it easier to adjust the depth of the punch.
Move the disc to the left and the punch will be pressed deeper.
However, if the punch is pressed too deep, sometimes the hole will be deformed or the material will rise up with the punch during the punching process.
Always adjust to the right position. If the punch is too deep, move it to the right to make it shallower.
Measure how deep it is in practice.
When the punch doesn't go through, adjust it by one or two frames, or turn it around.
When it is almost there, lock it tightly, using a spanner to lock the top nut.
After locking it tightly, turn on the air pressure and then operate it again.
This way the problem of not punching through will be solved.
