Search for CNC videos, those machines work in oily, soapy, dusty and full of metal shavings environments and do fine.
It's still a fairly controlled environment with splash guards, liquid based dusts suppression and or dust collection, even then my friend has a factory and the CNC is a reliable machine but things screw up.
If the dust collection was disabled, the workshop and the machine would be caked in debris.
It doesn't move, it doesn't fall over or have anything falling on top of it either (like a robot could).
