Cooling system for dril lpress

**Tuomas** · Feb 17, 2018, 05:34 AM

Hi

I made a cooling system to my second drill press too.
Actually, i can use same system with my mag drill also. Both hoses from fluid collectors goes to the same tank.

As a tank, i used old computer cooler. (Zalman reserator 1 )
I just changed bigger pump to it, used Eheim aquarium pump wich pumps 30 L/min.
Adjusted suitable flow speed for the cutting fluid directly from the pump. So, i don't need separate speed adjustment for the motor.

Collector is made from 1.5mm thick stainless 316 plate. Welds made with tig.

Used rubber cones as a feets, those are actually intented to be used to protect threads when sand blasting.
Feets are secured with strong epoxy.

Filter keeps hose open, its 3D printed and took 30 min to print, so its easy to change if it gets stucked.

Also hose clamp is printed. Magnet holds it in desired position.

Done:

Im going to upgrade my drill press soon, so made things easy to swap to the new one. Also collector is quick to empty when its unbolted.

Edit:

After consulting out cats i decided that its better to attach pan proberly to the drill.

Thanks Tuomas! We've added your Drill Press Cooling System to our Drilling and Drill Presses category,
as well as to your builder page: Tuomas's Homemade Tools. Your receipt:

Beautiful sheet metal work on the Pan Tuomas! Do you have to remove the pump to adjust the flow? They make ball valves for the linked nozzles but not sure it would be good for the pump? Nice idea and re-purpose of the cooling system.

Thanks. I don't need to remove pump. My hand fits inside the container, but after its once adjusted i don't need to change it anymore.
I have planned to add ball valve to it, but to the T-connector, in the way that when valve is closed, it guides coolant back to the container.

Not sure why you are worried about running the coolant back to the reservoir when the valve is closed. I've used aquarium pumps fountain pumps and swamp cooler pumps for cutting coolant for years Always had them wired so they could not be left on if the machine was not running but the pump switch could be switched off if I didn't want coolant. never had anything other than a valve on the coolant line to restrict flow. Those little plastic impeller centrifugal pumps always seemed perfectly happy running with the valve closed. the rubber impeller ones with a more positive volume/ pressure delivery not so much. but could get a couple years out of them even at that as long as I didn't leave them running against a closed valve for very long. I always prefer to have a pump run indicator light to remind me it was on of off when I wasn't using it but I never heard of using a return bypass line on one, maybe it might be needed for high volume pumps though. 30 ltr min. sounds like a pretty high volume pump Check the specs to see what the max head height and free flow volume at that height would be, .because the pump looks huge form the picture

Hi Frank.

Im not worried about the pump.
Bypass valve is also for "shaking" the coolant.
I use emulsion that is 96% water 4% concentrate.
It starts to separate after couple weeks if not proberly shaked.
With bypass valve i can let the pump do the job, instead of mixing them in the bucket or something.
Also it works for adjusting flowing speed, if necessary.
But i think with drilling, i can use the same setting with all drillings that i do. So, mostly valve is for mixing the coolant. ( little more effective way, when it doesn't need to run through whole system)

Really Nice clamp from a 3D print, Tuomas. Excellent addition!

Thanks buddy!

I decided to make my own container for the coolant.

Material is 3mm stainless 316. Very simple design, should house 20 litres. I tought i'll print the latch with fillport and hose fittings to the top. I have used 3d printer with this so much anyway.
