- Dielectric fluids for EDM fast hole drilling machines The solution... Human Technology for man, environment and machines
Superior fluids for all your applications Quality is the key to success! The Company which was founded by Carl Christian Held in 1887, has become the corporation group as we know it today. In his day, Held could never have imagined that his company would be amongst one of the leading manufacturers of high-tech lubricants Eroding fast hole drilling machines are no longer only used for start hole drilling. The call for more precision becomes louder in this section. oelheld GmbH accepted this challenge and developed two dielectrics for fast hole drilling machines which meet these requirements. In the following summary, we will outline to you just one example of the high requirements fulfilled by oelheld, in the newest innovation of dielectric technologies. Philipp and Martin Storr Managing directors At oelheld you receive sealed and certified quality since 1996. The certificates according to DIN EN ISO 91 and DIN EN ISO 141 prove our solid standards regarding product and service quality. Human Technology Human Technology technology is steht not bei just uns a trademark nicht nur at als oelheld ein Markenzeichen, - it is a guiding sondern principle. für Low eine risk Firmenphilosophie. potential as well as Geringes environmental Gefährdungspotenzial safety of the products sowie and die Umweltverträglichkeit the application are most der Produkte important und for us. Produktionsprozesse stehen im Vordergrund. Aus Following diesem the Grundgedanken principle we develop heraus fluids entwickeln that are wir best-suited Fluids, die for einerseits the application einen optimalen of our Bearbeitungsprozess customers but also provide beim Kunden the best ermöglichen, possible health andererseits environmental aber immer aspects. Therefore our gesundheits- production plant und is umweltrelevante based on special Aspekte sealed floors möglichst and optimal equipped berücksichtigen. with the latest blending technology which provides additional safety. Human Technology für Mensch, Natur und Maschine unser Human Beitrag Technology für eine for bessere Man, Environment Zukunft! and Machines our contribution toward a better future! 2
High-quality precision holes when using IonoVit High-performance dielectric This new development by oelheld, a water-based medium which contains proper additives, guarantees the manufacturing of reproducible and high-quality holes for electrode diameters of,1 3, mm and larger. is delivered ready-to-use. The brix-value is in a range of 5% - 7%. A dielectric aggregate (water treatment) is necessary, which is responsible for a good quality in cooperation with the mixedresin cartridge. The medium should be cooled as otherwise a steady performance cannot be reached. Measuring device: - Refractometer 5% - 7% Brix (water down only with deionised water) - Conductivity meter: conductance - 1 μs/cm - ph-value test strip 5-7 Peripheral requirement: Water treatment - Dielectric aggregate with filter and deionised resin absolutely necessary - Integrate the cooling coil into the cooling system - recommended for reproducible quality (option) - - Good electrode quality (electrode with bar) - Your benefits - Steel machining - No corrosion formation - Free of heavy metal and chlorine compounds Heavy metal machining - No visible cobalt leaching at bore entrance - Technological changes at the machine are not necessary - No machine soiling - Free of heavy metal and chlorine compounds 3
IonoVit S for quality fast hole drilling machines High-performance dielectric is a high-performance dielectric designed for economic and fast working from an electrode diameter of,5 mm. It is also suitable for the processing of aluminum. Work pieces made of ferrous metals are temporarily protected from corrosion. is a ready-to-use product. The concentration is regulated using a hand refractometer: The refractometer display for the ready-to-use is 7, % Brix. Measuring device: - Refractometer 7% Brix (water down only with deionised water) Peripheral requirement: Water treatment - Dielectric aggregate with filter - Integrate the cooling coil into the cooling system - recommended for reproducible quality (option) - - Normal electrode quality is sufficient - Your benefits - Human Free of Technology heavy metal steht and bei chlorine uns nicht compounds nur als ein Markenzeichen, sondern für eine Firmenphilosophie. Geringes Gefährdungspotenzial sowie die Umweltverträglichkeit der Produkte Low electrode und Produktionsprozesse wear stehen im Vordergrund. No foaming Aus diesem Grundgedanken heraus entwickeln wir Fluids, die einerseits einen optimalen Little Bearbeitungsprozess time exposure beim during Kunden drilling ermöglichen, andererseits aber immer gesundheits- und umweltrelevante Aspekte möglichst optimal berücksichtigen. Temporary corrosion protection Human Technology für Mensch, Natur und Maschine Mild in odour unser Beitrag für eine bessere Zukunft! 4

Peripheral products Water treatment For the application of and a dielectric aggregate is required. If none is included in the machine, the DA 6, can be used. Important: The recommended cooling guarantees a reproducible quality with both products. The cooling coil is not included (option). Hand refractometer This measuring device is necessary to measure the concentration of these products and, if required, to adjust with deionised water. ph-value test strips The quality inspection of the water quality at takes place by using ph-value test strips. Conductivity meter When using a water conductance smaller than 1 μs/cm is required. At a value bigger than 1 μs/cm the resin cartridge has to be changed. 7
