I have just purchased a Boxford Lathe

[Hood]

Just collect the coolant below in another can and drop feed from above

Not really going to be FLOOD coolant then

Ok central heating pump it is then what kind of filter do I need and what type of coolant

Not really going to be FLOOD coolant then

it doesn't need to be flood just a constant small flow

 

[123hotchef]

I am up for trying it out. What kind off coolant do I need

 

[123hotchef]

I figure my special mix for the pillar drill won't suffice.

 

[brightspark]

I use rocol but there is a lot of other products a lot cheaper that is probably just as good without the brand name

 

[123hotchef]

Better than my veg oil water and washing up liquid mix

Flood is better if you are wanting to stop the thermal expansion which I think was the main point of considering getting coolant.

in industry but not realy in a home workshop no rush . if I'm drilling or cutting and it gets 2warm I just let it cool down and start again . coolant lubricates gives a better finish and the tools stay sharp longer if I ever drill holes I use cutting compound . even on hacksaw blades

 

[123hotchef]

I can let it cool.between drilling and tapping no bother

But that was what was being discussed here, tapped hole going tight once cooled. Flood coolant was suggested as an alternative to removing from chuck and getting on drilling another etc until they had cooled and could be rechucked and tapped.

All up for improving the machinery especially if I have the bits already to do it

This is a decent cheap coolant I have used although I now use their synthetic.

What is better. Is that a 5 to 10 percent mix of water or coolant

 

[Hood]

The fully synthetic is 5% if I recall where the semi is nearer the 10%. The fully synthetic actually works out cheaper for me and I prefer it on the mill due to it being a green translucent colour so you can see what is going on. Not something that is really needed for lathe work though.

 

[123hotchef]

Is that 10 percent coolant 90 percent water

I take it being recirculated it lasts a while too

 

[Hood]

20L lasts me at least a year and I have 3 machines running it, well 4 if you count the beaver mill but that never gets used now since I got the Chiron.
The manual lathe uses the most as it gets splashed about on that. The CNC lathe and the Chiron hardly use anything as they are fully enclosed and they actually need topped up with water due to evaporation more than they need topped up with mix.

how big does the tank need to be for the suds? and is it 90% water 10% oil mix

 

[Hood]

I would say you would be best with about 20L although smaller would likely be fine.
Yes it would be 2L of oil to 19 of water although likely that would be to much. I think normally when I was using the semi synthetic it was about 1.5L I used.

Edit
typo with the amount I said 1 rather than 2 but fixed now. Also it is probably more 20L of water as I just fill up a drum and they usually hold more than 20l. You don't have to be precise but I usually use the scope to get it to the mix I want.

so do you just use a drum for the tank? or something else?
I am thinking copper pipe to the heating pump or speedie fit pipe.
Just need some ideas for a filter
