Exploit the advantages of metal-bonded grinding wheels in the grinding process

In the grinding of tungsten carbide, ceramics and hardened steels, metal-bonded grinding wheels have huge advantages over the grinding wheels with synthetic resin bonds currently in frequent use. They are much more dimensionally stable and permit significantly higher grinding feed rates – for previously unattained productivity.

The constant challenge of boosting precision and effectiveness while reducing costs can be achieved with metal-bonded grinding wheels. The previously highly elaborate dressing process can now be superseded by wire EDM systems with the V350 generator from Mitsubishi Electric.

Mitsubishi Electric V350 – the generator for the best grinding wheels

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.

The Alfa Romeo Racing C38-Ferrari

Mitsubishi Electric has been a partner of the Formula 1® team for many years, and over 26,400 workpieces are machined on Mitsubishi Electric EDM systems each season.

For Alfa Romeo Racing, every millisecond of lap time counts, and the demands on precision and performance are extreme.

No mechanical forces, sharp abrasive grain and complex contours. Reproducibly precise results.

Grinding wheel geometry

Precise grinding wheel geometry with a deep profile.

Concave and convex profiles

Even complex geometries can be realised on a grinding wheel with wire EDM. For conventional dressing, three grinding wheels would be required for this geometry – with EDM, a single wheel is sufficient.

Contour fidelity

Metal-bonded D46 diamond grinding wheel, diameter 70 mm, double V-groove with inner radius r = 0.05 mm

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.

Contactless

Metallically bonded CBN grinding wheel B25/V240, tapered geometry with a 60° angle accurately produced all-round

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.

Intact grains

Metal-bonded D46 diamond grinding wheel, multiple profile D = 150 mm, inner and outer radius r = 0.12 mm ± 30°

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.

Contactless, precise and no compromises

Uncompromising

During machining, the bond of the grinding wheel is removed to the desired grinding contour. The abrasive grains that are no longer bonded drop out of the grinding wheel.

As a result the remaining structure of the grinding wheel is characterised by protruding, sharp exposed abrasive grains creating greater chip clearance and performance.

This significantly improves grinding performance, i.e. grinding feed rate, and grinding burn is avoided. At the same time, the service life of the grinding wheel is extended several times due to the considerably reduced mechanical and thermal stressing.

Smart technology, simple, exact, automatic.

Simple

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.

Exact

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.

Automatic

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.
