The SintoGrind series is a revolution in the toolgrinding market as the surface finish and the redressing cycles are improved while the operators health is not damaged. Also SintoGrind TTK can be used with any filtration system and is causing no foam problems. Nowadays the fully synthetic PAO based grinding fluids of the SintoGrind series are recommended by nearly all leading manufacturers of toolgrinding machines and used by countless end customers all over the world.

Also for the „Two-in-One machines“ of Walter Maschinenbau GmbH from Germany oelheld GmbH has developed a special product called IonoGrind that is able to manage booth processes - grinding and eroding.

Still today some of the grinding machines have to use water soluble products. As Matjaz Cajhen was working for many years on the grinding machines himself he experienced the problems when grinding tungsten carbide or PCD with water-soluble products very well: Cobalt leaching, foaming, dirty machines, short sump life and last but not least skin irritation. More than 5 different products from different manufacturers were tested previously.

When oelheld GmbH launched the watersoluble products of the new AquaTec series Mr. Ken Bausch, oelheld export sales manager and person directly responsible for the care of CAJHEN REZILNA ORODJA D.O.O., immediately contacted Matjaz Cajhen to ask whether a test would be possible. After a short discussion booth agreed that the AquaTec 5001 would be tested. After 6 month testing period Mr. Ken Bausch dicussed the results with Matjaz Cajhen to find out whether the AquaTec 5001 is meeting the high demands or any modifications have to be done. Matjaz Cajhen answered: “Do not touch the product – leave it as it is!”

This was very good news for a product that was just launched on the market and also increased the confidence in the AquaTec 5001 at other customers. In the meantime the AquaTec 5001 is used worldwide on many tungsten carbide grinding machines like cylindrical grinders, surface, profile and centreless grinders.
