Handling and care of water-miscible coolants

Before filling

Filling

Initial fill or re-filling

Proceed as follows

Water quality

Before filling or re-filling the system, absolutecleanliness is essential. Thoroughly clean themetalworking fluid tank and the machine of all
chips, swarf, sludge and other residues.
– 	Add system cleaner to the old emulsion as perrecommended dosage. Then work with this mixture so that the cleaner can circulate throughout
the system.
– Drain the system.
– 	 Clean the machine with a high-pressure sprayand rags.
– Remove residual fluid out of the machine for 		
waste disposal.
– F ill the machine with diluted fresh emulsion(at least 1% concentration) to the level requiredfor pump suction intake.
– L et this diluted fresh emulsion circulate for atleast 30 minutes. During this time turn the chip
conveyor on and flush all the nozzles as well as
the internal coolant.
– Remove this emulsion out of the machine for 		
waste disposal.
– F ill the machine with fresh emulsion at therecommended concentration.

Measures during
operation

The metalworking fluid emulsion is mainlycomprised of water. The water quality (chloridecontent, hardness and pH) ­varies widely by region
and country. Poor water quality can cause negative
effects on the metalworking fluids, machine partsand components.

Monitoring
Concentration

Should be as low as possible, no more than
25 ppm.
Varies according to product. For most Blaser
products 90 –270 ppm water hardness is ideal.
Softer water promotes foaming. This can b­eavoided with most Blasocut and some B­ -Cool
products by adding calcium acetate to harden
the water.
If the water is too hard (>270 ppm), tap water
can be used for mixing new emulsions, but fordaily topping-off it is better to use water that is­de-mineralized or treated by reverse osmosis.

In order to detect adverse developments andaddress them in a timely manner, regularly checkthe following parameters:
Keep the concentration within the recommended
range. This ensures the optimal metalworking
fluid condition for best machining performanceand corrosion protection with minimal foaming
and long term stability. Top-off concentration canvary and is generally lower than the actual working concentration in the machine.

Topping-off frequency

Keep the coolant sump as full as possible byfrequently topping-off. This maintains constantemulsion conditions as well as providing consistent, reliable machining parameters.

pH value

The pH value indicates the condition of themetalworking fluid during use. If the pH value
is above the maximum or below the minimum
limit, then corrective measures need to be taken.
We recommend checking the pH value weekly.

Concentrate: min.+50°F / max. +86°F

Never mix the existing metalworking fluid with anyother product.

Metalworking fluid
maintenanceImportant: Never add water alone or straight­con­centrate to the metalworking fluid emulsion.

Tramp oil removal, filtration

We recommend using a Jetmix or Minimix to makea finely dispersed, homogeneous emulsion of
metalworking fluid concentrate and water.
First fill a container with water. Then add the rightamount of concentrate while stirring continuously
until it is completely dispersed. (A hand held drill
with mixing attachment is suitable for stirring).
Do not use compressed air, a water jet, or any­metalworking fluid pumping system!

Tip: Measuring intervals depend verymuch on the tank size. Central systems
should be checked daily, and individually filled machines on a weekly basis.
We recommend keeping a monitoring
log of all measurements taken, and canprovide you with a template accordingly, if desired. Do not hesitate to contact
us in case of any unusual changes
observed in measurement data.

A minimal effort in metalworking fluid maintenance is a good investment
Efficient filtration and regular removal of thetramp oil with a skimmer are enough to keep
the emulsion in optimal condition. Good fluid
maintenance promotes long sump life, thus
reducing coolant disposal and expensive additive additions.
