Shift in the shaft. 🔧
In highly complex automation systems, one topic is often underestimated:
👉 NIO handling (NOK)
Because of course: Everyone optimizes for quality and minimal scrap rate.
But what happens when parts still need to be rejected?
In the picture, you can see the drop shafts installed in a 3 × 9 m system. Here, over 20 stations perform assembly, testing, and measurement tasks, which for NIO management means:
➡️ Multiple drop shafts
➡️ Clear NIO classifications
➡️ Continuous monitoring & counting
Sounds simple – it isn’t.
The reality in engineering:
✅ No jamming in the shaft
✅ Safe arrival in the correct box
✅ Master different component geometries
✅ Ensure 100% clean software logic
Why this is crucial:
NIO is not an exception – it is an integral part of the process.
And this is exactly where stable automation separates from fault-prone automation.
💡 Takeaway:
The scrap rate should be minimal – no question.
But a truly good system is recognized by how precisely it handles all eventualities.
