picked up an old cold saw I need help with

[broncorob]

I picked up a Bewo 315LT a few weeks back. It's in pretty good condition and I got her running last week(had to bring 480V into my shop from the plant). This is my first cold saw and really the first time I've ever used one. It is already making life so much easier cutting tube and steel.

My question is about the cutting fluid or coolant. It's got a resevoir under the saw and a pump that pours it on the blade. When I got it it had some coolant left in there but it's old and nasty. How do I clean it out in there? What type of coolant is it? I see VanSant has the stuff for $35/gallon, but that seems awfully steep.

this is what we use in our cold saw. we used to use the same white/milky coolant that we run in the machining center and lathe, but recently switched to this. it seems like it cuts better, and a little cooler. the only problem i have noticed is that there is a little more rusting on the bare steel surfaces of the saw after periods of non-use. the white coolant would leave a film that was a little more protective.

to clean it, it depends on what you need to remove...if its oily film, i'd try Simple Green. first i'd drain the tank and clean out as much crap as possible, run the simple green thru it, and clean it again. i clean out our cold saw about once a year...and it sucks. i'll pump as much of the coolant as possible into a bucket and then shop-vac the rest out with any chips that may be in the bottom of the tank. then i go at it with a rag and simple green until the tank is clean.

Post up a picture if you can Im curious what this beast looks like.

I tried to Google it but whatever that language is that comes up I cant read it :laughing:

It is almost the exact same saw as this http://www.scotchman.com/specs.php?index=25.
Jeepnmatt, do you think adding a rust inhibitor may help it out? I go through spurts of working with it and it may sit for a couple of weeks and not get used at all.

Dang...lucky bastid. You got it for really cheap too didn't you? Is coolant even necessary if you'll only use it a little bit?

Hey guys, this Trim-Sol that we have is kinda pricey, we have had customers asking for it because they say its better for cooling and protection. DAKE sends it out with all their saws because they have found it best for blade life. Remember, products like TRIM-SOL are deluted with water about 5:1, so one gallon of product makes 6 gallons or so of coolant, which lasts a long time!!!

Good to know Alan. Is the "E-206 Water Based Saw Coolant (gal)" the "TRIM-SOL" you are talking about?

Do you know how much fluid this saw will hold?
Thanks

Yeah, thats the stuff. Not sure what that saw will hold, maybe a gallon or so? You should be able to refill your saw a few times with it, and that should last you for a long time, assuming you aren't using it 50 hrs a week!

Thanks Alan

Ive used one chlorine tablet, like those in swimming pool filters, to keep the stink and bacteria to a minimum on our tools that use cutting fluid. I use the mobil 1 water soluble cutting fluid. Mixes 20:1 water to oil. Seems to work well, for low volume stuff.

the next time i'm adding coolant to one of the machines, i'm going to mix a little of the water-soluble oil (milky white stuff) in with it to see how that does. its not really that big of a deal. we usually just blow it off with a blow-gun and then mist it with WD-40 to prevent rust.
