Coolant Concentration Tester

Coolant Concentration Tester - Intuitively, i had assumed that that would simply mean adding 16l of concentrate to 184l of water, however, upon asking a machinist colleague he informed me that due to the refractive index of the coolant (1.5), i would actually only need to use 5.3% (10.7l) of the coolant concentrate to achieve a true concentration of 8%. I repeat the cycle until the coolant is almost gone, and i start all over again. When the makeup of coolant breaks down, the concentration of the coolant ingredients become weaker and less effective. I don't think there is any truth in the different materials affecting coolant. Every time i need to refill the coolant tank, i pour about 75% of the 5 gallon pail, and i refill again with water. Remember concentration control is the key to metalworking fluid success. To check the concentration of coolant you’ll need to use a refractometer. I run cast iron, cast alum, cast stainless, 1018 crs, 4140, 303,316,416 ss, 6061 alum, 2024 alum, and alloy 145 copper all on the same coolant. We are already use a refractometer for concentration, and we have 2 coalescers in that sump to keep it clean. You need good lube and cool temps for those super alloys.

Every time i need to refill the coolant tank, i pour about 75% of the 5 gallon pail, and i refill again with water. After filling the machine with the correct concentration, i make a 5 gallon pail with about half of the concentration. When the makeup of coolant breaks down, the concentration of the coolant ingredients become weaker and less effective. Staying at 10% works because i may run 12l14 and 316 stainless in the same day on the same machine. If you are going to use a brix refractometer to measure concentration you should have a graph that reads in bx vs. Intuitively, i had assumed that that would simply mean adding 16l of concentrate to 184l of water, however, upon asking a machinist colleague he informed me that due to the refractive index of the coolant (1.5), i would actually only need to use 5.3% (10.7l) of the coolant concentrate to achieve a true concentration of 8%. To check the concentration of coolant you’ll need to use a refractometer. That low concentration can cause damage to tool and machine life. Remember concentration control is the key to metalworking fluid success.

Every Time I Need To Refill The Coolant Tank, I Pour About 75% Of The 5 Gallon Pail, And I Refill Again With Water.

I run cast iron, cast alum, cast stainless, 1018 crs, 4140, 303,316,416 ss, 6061 alum, 2024 alum, and alloy 145 copper all on the same coolant. As an example one of the cleaning chemicals we use at 100% concentration has a reading of about 50 bx, but a s.g. Hangsterfer's is a reputable coolant supplier, and should be able to help you with their various products. Staying at 10% works because i may run 12l14 and 316 stainless in the same day on the same machine.

On Top Of That There Is 10 Micron Filtration On Most Of The Coolant Systems That Are On That Machine.

That low concentration can cause damage to tool and machine life. If you are going to use a brix refractometer to measure concentration you should have a graph that reads in bx vs. Or, as wikipedia explains it, one degree brix is 1 gram of sucrose in 100 grams of solution and represents the strength of the solution as percentage by weight (% w/w. This device uses a special scale, called brix scale, to show the density of the water.

We Are Already Use A Refractometer For Concentration, And We Have 2 Coalescers In That Sump To Keep It Clean.

I repeat the cycle until the coolant is almost gone, and i start all over again. A 10% concentration of alcohol is water is going to have a completely different refractive index (the value the refractometer measures) than a 10% mix of soluble oil coolant. We want you to be machinists, let us worry about the chemistry. Concentration for the given mixture.

At 10% It Has A Reading Of 6.2 Bx.

What i need to know is how much way lube, hydraulic oil etc is getting emulsified in the coolant. If maintained properly, your coolant should give you many months, if not years of service life. After filling the machine with the correct concentration, i make a 5 gallon pail with about half of the concentration. Intuitively, i had assumed that that would simply mean adding 16l of concentrate to 184l of water, however, upon asking a machinist colleague he informed me that due to the refractive index of the coolant (1.5), i would actually only need to use 5.3% (10.7l) of the coolant concentrate to achieve a true concentration of 8%.
