CNC BUILD 2.2kW spindle Water pump

I am building a CNC Router in my garage. As you do.
This video shows me adding the coolant pump to the water cooled spindle and spinning it up for the first time on camera.
I have made quite a few videos of this build that can been seen here:

I also have a build log on MYCNCUK which can be seen here:

Great to see you up and running. The trick with most cooling systems is to know that they are working correctly. If your spindle doesn't have a temperature sensor, you could attach a simple aquarium sensor or similar to the spindle so you can know that the spindle is in its normal temperature range. Another trick is to have the submersible pump actually in the coolant tank so if your tubing slips off the pump, it doesn't flood onto your workshop floor. I saw you have it in a tray which works as long as the tray is larger than the coolant volume. Cheers and happy CNC'g.

Thanks for the tips!

I use an AIO cooler off of my water-cooled computer . Fan, radiator, and pump work perfectly.

[@moisesmancano4323]

Hello, how can I find this blue reducer like yours in stores? What are its specifications? Thank you very much.

[@drpipe]

Why so much antifreeze ? Even if you put 20% wouldn't it be more than enough ?

[@sitgesvillaapartmentneilsc7924]

Can I ask why you went for an open cooling circuit on your spindle rather than a simple PC/computer closed circuit system using a fan and high efficiency pc radiators? Just an idea, lot less tubes and mess and with a temperature sensor and flow meter built together with a temperature alarm would that not be better in view of your sizeable investment? Just curious, no disrespect to your system. You could add silver also to the solution as a disinfectant as well.

[@forevertight]

I'm also interested in the answer.

[@sitgesvillaapartmentneilsc7924]

Drop a piece of anti bacterial silver into the tank to keep the water sweet. cost about 5 quid on ebay, works all the time on my laser and cnc.

[@bw0704]

Can you say what model spindle you're using and how much it cost? Is it 80mm diameter motor?

[@davywavy5364]

Could you give out the details for the pump as I am in desperate need of one. Please

[@MrX-il3qo]

Yeah but what kind of water pipe is suitable for a CNC on the tracks as will bend all the time?

[@manishchauhan9495]

What coolant liquid you used for cooling ?

[@yasirh2004]

Whats the size and voltage of that submarine water pump

[@The_Unobtainium]

what do you think about this spindle? Is it worth it for DIY router?

[@WoodomainJeremyBroun]

Hi. the link to the Ebay water pump doesn't work. Can you say what the spec is please?

[@russdog63]

I have what looks like the exact same pump. It is a 12 volt DC 19 watt pump. It claims to move 800 L/hr with a 5M head. That is some decent specs for such a little pump. It looks like the flow was pretty good through that long length of tubing. I got mine on ebay but don't recall the vendor.

[@sonuverma2796]

Sir which chemical mix with antifreeze

[@DalyMalcolm]

Hey joe, lovely setup you have there, where did you get that little water pump from? It’s looks like it has a good strong pump, I’ve found finding a decent pump quite hard. I like the idea of using antifreeze as a coolant too, I take it that won’t damage any of the parts?

[@joerharris]

Hi Malcolm, yes it seems to work ok! The pump was from ebay: rover.ebay.com/rover/0/0/0?mpre=https%3A%2F%2Fwww.ebay.co.uk%2Fulk%2Fitm%2F302532454321 took a while to arrive but seems good enough. I figured the anti freeze wouldn’t do any harm and will stop things growing I hope!

[@DalyMalcolm]

That’s great joe thanks, what about those blue pipe fittings, have you got the link for them too? Thanks again

[@joerharris]

They were from fleabay too! rover.ebay.com/rover/0/0/0?mpre=https%3A%2F%2Fwww.ebay.co.uk%2Fulk%2Fitm%2F172494423374

[@AlJay0032]

Why are you putting antifreeze in at all?

[@victormaniaci2104]

Probably lives in cold climate and doesn't want the water to freeze and break things every winter.

[@tomadams1066]

That looks like a nice water pump. Where did you buy it? Or is it a secret? Tom Jacksonville, FL US

[@tomadams1066]

I found it below, sorry.

[@vais1000]

What coolant do you use?

[@joeygonzo]

anti freeze coolant

[@JyskMaker]

Set it up high, a wather pump have a lifting height.

[@CoryMck]

Energy spent pushing it up is conserved when it has to fall back down.

[@fl3m4fisherman80]

Help error e.co.a

[@genel.8582]

What was the clear liquid that you poured into the tank after the antifreeze

[@joerharris]

Just some de-ionised water

[@msdesignru]

OK
