440 Chip Management

Now that the flood coolant is working on my 440. The chip management seems it could be improved. Has anybody made modifications for better chip management to their 440?

@BRIAN_TAVARES sure did.

Your stand looks fantastic. I’m just looking for a way to or suggestions to modify the factory system. it seems that making the drain outlet and hose a larger size would be a step in that direction.

Yes, I did several things, first was to put in a much larger capacity submersible pump (I think 1.5HP?) and use an off machine reservoir in a giant rubbermaid container that holds 6+ gallons, the return hose dumps into a 8” diameter very fine mesh sieve that traps virtually all the chips, finally there is an inline hose filter that removes the fines. If the case sealed better I would put in wash downs but it doesn’t I’ve put in an acrylic overlap for the doors to try and prevent spray from going between the doors, and 2 45 degree deflectors on the doors to prevent spatter from running down since the bottom lip just shuts coolant outwards. This was all super cheap

Smalls filter (works amazingly well). Not sure why the filter looks cross threaded in the photo, but it’s not. I just 3D printed the bracket in PLA, and since nobody is behind the mill didn’t even bother to secure it down, it’s never moved. And while PLA is a “terrible choice” per the masses, it’s now 7 years old and still holds the filter…

Sieve (the chips around the filter are purely due to my incompetent scooping into my chips bucket

Return hose into the sieve (3D printed 90 degree nozzle) and the braided steel covered high pressure line out. Yeah, it’s a little ghetto/swamp cooler’ish but honestly works great, I have 3 flood nozzles off a manifold on the spindle. Total setup was around $100.

Henry, thanks for the ideas and taking time to share your pictures. That look like something I’ll try.
