Service Overview
We built this grooving station. It goes into cylindrical battery lines.
What does it do? It cuts a groove near the top of the can. That groove holds the top cap. It also seals the cell. Pretty simple actually.
Here's how. The machine has a spindle. Precision type. And forming tools. They press against the can wall. The metal bends but doesn't crack. We checked.
This station only does one job. It sits between the winding station and the filling station. That's it. No switching tasks. No reconfiguring. One thing over and over.
Once the groove is cut, the top cap sits right in place. Then the seal holds during filling. No groove? No seal. That's just how it works.
Leaks happen when the groove is bad. This station stops that from happening.

Performance characteristics
1. This machine uses a touch screen operation interface, which is easy to operate.
2. The hob is driven by a motor instead of a traditional cylinder (not limited by air pressure).
4. The machine has a vertical structure, which is convenient for product discharge and collection, has good consistency, and is suitable for batch production
5. The groove depth and width are adjusted by micrometer, with high precision and easy adjustment
6. The total height of the battery and the upper height can be adjusted with a micrometer
7. (Hob, head, tail) three-point positioning is accurate and highly adjustable
8. The upper head adopts a fine-tuning design to facilitate height adjustment
