EDM Dress – Profit for Grinding

The V350 generator from Mitsubishi Electric has outstanding properties for the dressing process and makes it possible to produce grinding wheels with a sharp cut. The result is open-porous grinding wheels with the best possible grain protrusion – for optimum grinding.

Precise grinding wheel geometry with a deep profile.

Wire EDM dressing of the grinding wheel enables the finest and most complex geometries. By using thin erosion wires, inner radii of r = 0.05 mm can be achieved on the grinding wheel. Outer radii are only limited by the grain size of the grinding wheel, and tapered contours can be produced with geometrical accuracy.

EDM dressing is a contactless process that does not apply any mechanical forces to the grinding wheel. This completely eliminates break-outs and contour damage in the dressing process.

The wire EDM dressing of grinding wheels is remarkable because only the bond of the grinding wheel is machined. The abrasive grains remain unaffected by the process and thus retain their natural shape and sharpness.

EDM Dress – the package for wire EDM dressing is supplied as a turnkey solution and can go into production straight after commissioning. All the necessary components and technologies are made available ready for use.

The wire EDM dressing technology is fully CNC-controlled and reproducible. Each grinding wheel is produced with geometrical precision and within the same tolerances every time.

Once set up, the dressing process runs completely automatically. Manual intervention is not necessary, and operator supervision is not necessary. This enables complete automation of the process at any time by automatically loading and unloading the machine.
