Dielectric

For die-sinking EDM, the requirements for an efficient dielectric are the following: top machining speed, best surface results, optimum dielectric strength, minimum electrode wear, neutral odour as well as low contents of aromatics and not hazardous to health. Expert knowledge is particularly required in this context to achieve more ignitions per unit and, consequently, shorter erosion times.

esgemo dielectrics provide highest efficiency for die-sinking EDM, from roughing to super-finishing. They are produced using a synthetic base and are physiologically safe. Their chipping volume is very high in all applications. They are equally suitable for copper and graphite electrodes and have a low-wear effect onto the electrodes.

esgeSparc SE 108

Multifunctional dielectric for sinking erosion

Application

esgeSparc SE 108 is a synthetic-based multi-functional dielectric fluid for the modern requirements of the newest sinking erosion. esgeSparc SE 108 is completely odorless and water clear. It is almost free of aromatics and particularly skin-friendly.

esgeSparc SE 108 was developed for the requirements of the mold and tool manufacturers in the field of plastics and die casting industrie. Due to its medium viscosity, esgeSparc SE 108 is ideally suited for the finishing and roughing applications. As a result, large workpieces can be produced on machines with high current ratings (> 60Amp), but also low roughness can be achieved. Due to the extremely low boiling range of only 12 ° C, esgeSparc SE 108 is a very innovative dielectric which guarantees a high removal rate while minimizing electrode wear.

esgeSparc SE 108 is waterclear to create high visibility of the machining process. Due to the high flash point, the best possible working safety is ensured. esgeSparc SE 108 can be filtered with all common filter systems.
