DIY through spindle coolant final update

I have gone as far as I think I want to at the moment with through spindle coolant. It only works!!!!!!

To me, I think the through coolant flow restricts at higher spindle speeds to the point to zero flow. The passages need to be redesigned from inverted firstly to outverted first. I'd start with a circular canal area in the metal body with passages starting from it on its outer diameter shaped like the edge of a arrow head spike with a negative rake angle of the 4 passages in the 2 difference planes if that makes any sense to you. The plastic water delivery system would need redesigning to match, but if the circular canal channel could have a circular form with a smaller diameter straight canal channel feeding it, you may get away with just drip feeding water down into it. To do this, it may need to be made out of more than one main piece. When running the spindle, this would be like a car water pump. I would enjoy watching this trying to be made. I hope you get my idea.

Thanks James,
I think I get what you mean. I feel the issues you highlight are correct. Centrifugal forces could indeed stop the flow of coolant. I wonder if that's why pro machines use a high pressure pump for spindle coolant. I made this because I thought is was a cool idea not sure if will ever catch on though. I have a new camera that does have a slomo function would be interesting to see if it can pick up any thing?
I will give it a try.
Cheers

Good work as always; this is clever. We shared this video on our homemade tools forum this week 😎

Thanks for sharing!

That’s a proper through coolant job. Top marks!

[@CazualHaze]

Thanks 👍

[@vdlizard]

Well done! That is looking like a really useful tool.

[@CazualHaze]

Thanks 👍

[@mattharrington4887]

Excellent - simple and effective!

[@CazualHaze]

Many thanks!

Maybe consider adding a removable 3D Printed "Fence" that can be added to the nonrotating part for catching and redirecting the fluid downwards that would otherwise get flung at you due to the centrifugal force of the rotating pieces above and below the static part? 🤔

[@CazualHaze]

Thanks Durahl,
That sounds a good idea. A static shroud would stop a lot of flinging about!
Cheers

Great stuff, I was wondering about the best way to make a metal replacement for the 3d printed parts, this is a nice and simple solution and looks like it works well.

[@CazualHaze]

Glad you liked it!

I wonder if you could add seals to each end of the sleeve to keep the coolant from leaking out so much, just a thought. Project looks great nonetheless.

[@CazualHaze]

You are right I think a lip seal at either end would make this a useful tool.

I used to work with Drills with internal Coolant.. works the exact same way..

[@CazualHaze]

Thanks @JanBinnendijk that's where the idea came from.
Cheers

[@jukkapekkaylitalo]

y could only use one circlip. If y leave lip on bottom of the tool and make, it slide on from the top. Then fix it in place from top by only one circlip.

[@CazualHaze]

Thanks that's a good idea the circlips were expensive!
