### Robot loading

The CNC AutoDoor comes with a control box requiring only two signals to open and close the machine door. This makes it a universal plug & play system, compatible with any CNC machine and all robot brands.

### Cobot loading

The CNC AutoDoor integrates seamlessly with cobots, including dedicated integration options such as URCap for Universal Robots.

### Productivity

Optionally, the door opens automatically when the machine cycle is finished, giving operators a clear visual signal and reducing waiting time. Customers report productivity increases of 10–15%.

### Ergonomics

Frequent manual opening of heavy machine doors puts unnecessary strain on operators. CNC AutoDoor automates this repetitive task, improving ergonomics and reducing physical strain.
