IME 56 is a dielectric for EDM die-sinking machines. IME 56 have been tested in extensive trials and have proven to be effective in practice for decades. The series is explicitly recommended by leading manufacturers of electrical discharge machines. IME dielectrics have the highest dielectric strength, are clear and almost odorless. Their color does not change during erosion. They reach the purity level of pharmaceutical white oils and are practically free of aromatic compounds. Whether in rough cut applications or for use in fine operations, the dielectric must meet the specific requirements of each application. The high-performance dielectrics for use in electrical discharge machining are manufactured on a synthetic basis and are therefore particularly resistant to aging.

IonoFil 80 is used to overcome wire eroding issues in dielectrics. Cobalt leaching is a problem that is difficult to get under control, especially when machining carbide. This iswhy oelheld, together with leading companies in the erosion industry and the University of Leuven (Belgium), has decided on a research project to develop a hydrocarbon-based dielectric that is directly adapted to wire cutting technology. Particularly the service life of carbide punches can be enormously extended by eliminating cobalt leaching. This development makes costly and time-consuming deionization of the water with resins, corrosion protection (before, during and after processing) as well as frequent changes of the medium a thing of the past. As a dielectric, IonoFil enables smaller spark gaps, which allow for smaller inner radii with the same wire diameter. The quality of the surfaces also increases to the same extent, which can be achieved with a coarseness of up to RA 0,01 much faster and more easily than with water.

IonoVit 0 is a water-based product with proper additives and guarantees the production of reproducible and high-quality drillings for electrode diameters starting from 0,1 mm. IonoVit 0 is a ready-to-use product, so that mixing is not necessary. The Brix value is in a range of 5% – 7%. A dielectric aggregate (water treatment) is required which, in combination with a mixed resin cartridge, ensures good quality and keeps the water conductance at less than 10 uS/cm. If the water conductance increases, the mixed resin cartridge must be replaced. The medium should also be cooled, because otherwise no constant performance can be achieved. For this product it is recommended to integrate a cooling spiral into the existing cooling circuit (recommended for reproducible quality).

IonoVit S is a high-performance dielectric designed for economic and fast working from an electrode diameter of 0,5 mm. It is also suitable for the processing of aluminum. Work pieces made of ferrous metals are temporarily protected from corrosion. IonoVit S is a ready-to-use product. The concentration is regulated using a hand refractometer. It is used for fast start hole drilling.

IonoGrind 105 is a innovative technology that makes one out of two: grinding and rotary eroding in one machine. This saves time and money. That‘s why oelheld developed a fluid especially adapted to this process. IonoGrind is a multifunctional fluid that is equally suitable for spark erosion and as a grinding oil. It was designed for use in combination machines (two in one) and combines the advantages of a high-performance dielectric for the extremely high removal rate and surface quality with a low-foaming and low-evaporation grinding oil. IonoGrind is the right medium for eroding and grinding PCD (polycrystalline diamonds), HSS and tungsten carbide, as its special composition prevents the release of cobalt. By using special high-pressure additives, IonoGrind also achieves maximum grinding performance.
