Hybrid_From_Hell Posted October 1, 2012 Share Posted October 1, 2012 As the header says need to add a coolant system to it Must be single phase the old unit was removed along with the dro when I got it as 3 hase Seen this : http://item.mobileweb.ebay.co.uk/viewitem?itemId=290708920441&index=3&nav=SEARCH&nid=01548903576 Any other ideas ?

CwazyWabbit Posted October 1, 2012 Share Posted October 1, 2012 I've used an older model of that coolant pump, works fine for me on a combined lathe mill machine. How big a mill are we talking about? Quote Link to comment Share on other sites More sharing options...
simonr Posted October 1, 2012 Share Posted October 1, 2012 I was going to suggest RDG or Chronos. Bits are usually cheaper from them direct than via eBay however. I had one of these on my old Lathe and it worked pretty well! I had to replace the pump on my mill as the old one was clogged with bogies (or something that looked like bogies!). I used a similar pump from one of the above as fitted it in the base of the mill as per the original. It still works perfectly years on.

Big.Mike Posted October 1, 2012 Share Posted October 1, 2012 The reservoir looks a little small for milling. You might want to buy a pump and make your own reservoir. I've used a 80 litre drum before. You need to be careful about the thing running dry, nothing worse than running out of coolant on the last pass!

vulcan bomber Posted October 1, 2012 Share Posted October 1, 2012 IIRC your mill has its coolant tank built into the base part of the machine.. Its a hollow casting on alot of mills.... you need just a pump and to replace the pipe work that might be missing. Quote Link to comment Share on other sites More sharing options...

GW8IZR Posted October 2, 2012 Share Posted October 2, 2012 If its just an emergency or temporary setup - you can use a bucket and let gravity do its stuff. Quote Link to comment Share on other sites More sharing options...
Hybrid_From_Hell Posted October 2, 2012 Author Share Posted October 2, 2012 Its a 'rather large' old Beaver Turret mill with power fee, belt driven head running 3HP 240V conversion I did on it ....its so old the tooling is 'International 30' on the drive head !! ..........anyone rememebnr them ! ??? good thing is the tooling turns up real cheap The "Sump" leaks, hence it had a external 3 Phase DRO + Coolant system The table has drains in each end, so thats easy enough to link into The 9 Litre system all conatined loks rather good, will 9 litres be enough of a sump / tank ? Prob just need to add some sort of coarse filter to the return - again any ideas anyone ? Nige Quote Link to comment Share on other sites More sharing options...
vulcan bomber Posted October 2, 2012 Share Posted October 2, 2012 Personaly i'd fix your sump because if you use the drains on the table you'll still get alot running from the table to the sump... That'll fillover time, start smelling really horrid and the leak through your leaky bit. When the drains clog on the mills at work the mess grows very rapid!

simonr Posted October 2, 2012 Share Posted October 2, 2012 I agree that 9l is too small. I seem to have to put about a gallon of coolant in for each job! As Vulcan says, only a proportion of the coolant ends up passing through the table drains. The rest is sprayed everywhere by the cutter! Quite a lot of it ends up running round the sides of the table and down the side of the knee-jack. Innevitably that will end up inside the base. I wonder if you could effect a seal by pouring liquid sealant (PU for example) into the base to the point it starts leaking - wait for it to go off then repeat until it stops? My base has a mesh covered plug hole in the bottom. I guess you could fabricate a funnel to fit the plug hole and mastic it in place. then connect the funnel with a hose to a separate tank?

Hybrid_From_Hell Posted October 2, 2012 Author Share Posted October 2, 2012 tank base was whallopped by a forklift many moon ago,more a chunk missing than a crack ! found this : http://www.ebay.co.u...8#ht_500wt_1414 30 litres sounds more like it - now am I barking in thinking of using a small piond pump a la : http://www.ebay.co.u...#ht_1747wt_1397 or even http://www.ebay.co.uk/itm/8W-600L-H-Mini-Aquarium-Tank-Pond-Fountain-Water-Filter-Pump-/320977859308?pt=UK_Pet_Supplies_Fish&hash=item4abbc572ec and then cobble u[p pipes to and from + filter on returns ? Thoughts ? Nige Quote Link to comment Share on other sites More sharing options...
Big.Mike Posted October 2, 2012 Share Posted October 2, 2012 You could try a pond pump, but I suspect the back pressure from the nozzle would stymie it. Oh, you need a non return valve in there too. The barrel looks okay. Taking Si's idea one step further could you line the reservoir in the base of the machine with a heavy duty polythene bag fill it with water and then concrete and rebar the hole. It's architectural, in this case weight is your friend! Cheers, Mike Quote Link to comment Share on other sites More sharing options...
zoltan Posted October 2, 2012 Share Posted October 2, 2012 I've been using a (Silverline ) pond pump on a small Myford cylindrical grinder. I know the coolant/water ratio is much lower for grinding but it has lasted surprisingly well and cost peanuts Quote Link to comment Share on other sites More sharing options...

Snap I have one of those. Nice machines. Is it one of the 'PAL' of VBRP' version? Mine has a fault on the Anilam CNC controler that I have not had time to fix. More usefully some suggestions: have you thought about metal stitching in a repair? Use some sheet steel and some set screws to put a patch over the hole. Seal it with some suitable seal and between the patch and base? Put some gaffer tape over the underside of the hole, rough up the surface of the hole, degrease and fill with an non shrinking epoxy or similar. Then paint with a tank sealer or similar? The original tank will work far better than trying to divert to an external tank IMHO. Adrian Quote Link to comment Share on other sites More sharing options...
simonr Posted October 3, 2012 Share Posted October 3, 2012 Agree - you are better off fixing the original. Even with something like Chemical Metal. If you use a separate tank you are going to need to pump coolant from the base of the machine into the tank anyway. I guess you could bury the tank in a hole to allow a gravity feed from the base? A pond pump intended for fountains would probably work OK. Si Quote Link to comment Share on other sites More sharing options...
steve b Posted October 3, 2012 Share Posted October 3, 2012 ...make a tray to sit the base in , high enough to match the sides of the base , fill with coolant , use ? A bund tray effectively cheers Steveb Quote Link to comment Share on other sites More sharing options...

A bund tray effectively cheers Steveb The tray would fill up with swarf and skank making it imho useless... hence why bridgeport and the like use the actual base. I still think you should repair the base Nige... Quote Link to comment Share on other sites More sharing options...
steve b Posted October 4, 2012 Share Posted October 4, 2012 I meant make it to the shape and size of the base footprint , it shouldn't fill with swarf as the coolant would be draining into the base as normal , just not running out of the broken out m/c casting. cheers steveb Quote Link to comment Share on other sites More sharing options...

ejparrott Posted October 5, 2012 Share Posted October 5, 2012 Warco make some. Believe it or not, the bridgeport clone I've been using to make the new CNC bits for my bridgeport clone, doesn't use normal coolant. He uses an air blast from a pond aerator, and its amazing how cool a 5mm cutter will stay, even when its 13mm deep in a slot 5.5mm wide. He has built an aluminium and perspex surround to his, sealed to the table with a single drain to a seperate tank.....if he evers fills it with coolant!

Believe it or not, the bridgeport clone I've been using to make the new CNC bits for my bridgeport clone, doesn't use normal coolant. He uses an air blast from a pond aerator... A jet of compressed air or a pump for an aerator is a really good way to cool work, in an enclosed mill. It would worry me in an open frame. At work I use MA Ford tools without coolant for stainless which we need to keep a high surface finish (it can really make a massive difference)... They are expensive, it does do away with the need for coolant. Their speeds and feeds are ridiculously fast! Quote Link to comment Share on other sites More sharing options...

I scared myself silly the first time we ran this fast, it's still an ar+e clenching moment the tool changes for the first time! Quote Link to comment Share on other sites More sharing options...
LandyManLuke Posted October 7, 2012 Share Posted October 7, 2012 That is quick!! I'm in the process of getting my bridgeport up and running. I don't have a lubrication system set up yet, so I tried using an air blast to keep the swarf clear of the tool. It worked well, but emptied my 300L tank way too quick, and stank!
