Digital knowledge portal for the maintenance of water-miscible cooling lubricants

As the cooling lubricant concentration changes during operation, it is essential to check the emulsion regularly using a handheld refractometer. Here we explain how you can quickly and easily determine the concentration of your emulsion yourself.

If the pH value of the cooling lubricant is too high, this can cause various problems - for example corrosion. Measurement using pH indicator sticks provides quick results.

Water hardness & quality influences the choice of cooling lubricant and the quality of the workpieces produced. In this video, you will learn how to easily determine water hardness using test strips and find out more about the relevant parameters that Zeller+Gmelin can analyze for you.

Regular measurement of the nitrite content of water-miscible cooling lubricants is not only required by law (TRGS 611), but is also important in order to work safely and for a long time with our Zubora products. Here we show you how to carry out the measurement professionally.

Emulsions are constantly under attack from microorganisms (bacteria, fungi, yeasts). This video shows what influence microorganisms have on your cooling lubricant, how the problems can be remedied and how you can prevent infestation.

A clean machine is a prerequisite for successful chipping. In this video, you will get important tips on machine cleaning and care and learn how supplementary Zubora products can support you.
