5 Axis Trunnion Indexer Safety

- Always check your programs rapid moves.

Watch for rapid moves into the trunnion and the work-holding device.
- Always check on the wiring to the trunnion.

Make sure that the cutter stays away from the wiring.
- Watch for tool changer clearances.

1. Tools may “Z” down when making a tool change.
2. Make sure that the table moves to the tool change location before each tool change.
3. The tool change location is when the table moves towards the front of the machine and all the way to the right of the machine.
