  • 3DS surfaces offer the following advantages:

    • In terms of appearance and quality = adjustable degree of gloss of the plastic part and improvement of the anti-scratch characteristics

    • Special advantages are shown by the reduced adhesion of the plastic part in the injection mold, thus enabling increased demolding speeds.

    • Less residue accumulation in the injection mold = reduction of the cleaning and maintenance times and costs of the injection molds and thus longer spraying autonomy

With our new high-precision die sinking EDM machine for the micro range, we are able to erode the smallest, fine cavities, slots and contours of all kinds. The big advantage over conventional die-sinking EDM processes is that we can achieve the smallest corner radii of less than 0.02mm with a smaller number of electrodes. This enables us to reduce production costs and are therefore more productive.

The extremely high repeatability provides the perfect machining accuracy that is required. Due to the exceptional surface quality and the highest level of detail, even when using microelectrodes, parts with the highest demands can be eroded. By producing 3DS surfaces, an improvement in the anti-scratch characteristics of the plastic parts to be injected can be achieved, an adjustable degree of gloss of the finished plastic part. Furthermore, the 3DS surface process offers a reduction in the adhesion of the plastic part during the injection process in the tool and thus an increase in the demolding speed during injection. Due to the reduced adhesion behavior, the accumulation of residue in the mold during the spraying process can also be reduced, which reduces maintenance times and costs and increases productivity.

  • No breakout of the binding matrix components when dressing profile grinding wheels

  • Processing of special materials such as ceramics or hard metals.

  • Machining or dressing of CBN or diamond grinding wheels (the binding material and the carrier must be electrically conductive)

  • Other workable materials such as hardened steels, steel and alloy steels, stainless steels (INOX), non-ferrous metals.

With our new rotation axis, a wide variety of shapes, the finest grooves, filigree profiles and small radii or surfaces on round parts can be made contactless, i.e. without any force being applied to the workpiece. The axis of rotation is always used when deep, fine grooves or small corner radii on round parts can no longer be produced by turning or cylindrical grinding.

The axis of rotation offers great advantages, especially in the area of grinding wheel dressing, in that required profiles with fine inner radii of, for example, r = 0.05mm can be created. With this process, profile accuracy in the µm range can be achieved with high concentricity. The prerequisite for this is always that the workpiece to be processed is electrically conductive. Another advantage of EDM grinding is that there is no heat input into the workpiece during the work process, which means that there are no structural changes in the material, such as those that can occur during turning or cylindrical grinding, for example.
