Jiaye Xinda nb-200 binding machine punching failure

The solution to this situation is as follows:

1. The drill fails to drill through the paper and returns, and the machine issues an alarm: The drill may be blocked by paper scraps due to improper operation. Or the cutting edge of the drill has been blunted; when this happens, you can try to clean the paper scraps in the drill, then sharpen the drill and try again.

2. The drill bit will swing when rotating: When this happens, you can check whether the drill bit is deformed and bent. If so, the drill bit needs to be replaced.
