- Ø.0275" +/-.0003, .450" deep (blind), 60 holes per part
- Only making 15 parts, so 900 holes total this size
- We put a ton of these size holes in other parts, but this is the first time seeing a blind version. The question is, how in the hell do we get our coolant out of the holes? We're running Oemeta Hycut at 8%. Currently we are pushing a .027" gage pin in each hole to push coolant out. That takes 3 goes in each hole to be satisfied there's hardly any coolant left in the hole. Then, the plater will run them through an agitated solvent batch and blow each small hole out with the smallest air nozzles he has. The parts will then get clear alodine.
The customer is working on a definition of "clean" as it pertains to this particular part, but 'probably' we just need to get the majority of the coolant out. They don't need to be surgically clean. Puting smaller vent holes in the back of the part is an option, but they would rather find a cleaning solution.
