XA GRINDING WHEELS IN CUBITRON<br />

Our grinding wheels in microcrystalline Cubitron corundum make it possible to improve grinding<br />

performance significantly, especially on steels of over 55 HRC in hardness, and to work easily even on<br />

extremely hard steels.<br />

While working, the abrasive granule<br />

wears and shear stress increases<br />

CONVENTIONAL ABRASIVES<br />

Shears stress overcomes resistance of bond<br />

and expels the granule<br />

This is all possible thanks to the specific structure of these abrasives: traditional corundums wear or<br />

fracture in a macroscopic manner during grinding, thus reducing the duration of the wheel’s grinding<br />

properties, especially on hard materials.<br />

In contrast, each Cubitron granule consists of tiny crystals which during the action of the grinding wheel<br />

generate microscopic fractures, thus losing a minimal portion of abrasive but keeping shear stress and<br />

the resulting grinding wheel wear constant.<br />

low-cost centre<br />

The negative aspect of Cubitron is its high cost: around 10<br />

times that of traditional abrasives. This means, for example,<br />

that the price of a grinding wheel with 30% microcrystalline is<br />

double. Therefore we have designed grinding wheels with a<br />

low-cost centre in which the part which is not used and<br />

manufactured with traditional corundum.<br />

Although the cost of the grinding wheel remains relatively high, we are able to optimise the performanceto-cost<br />

ratio by using the absolute minimum percentages of microcrystalline for the work to be done.<br />

In practical terms, the advantages of these grinding wheels are:<br />

increased grinding performance<br />

reduced grinding wheel wear, as it is dressed less often<br />

absence of burns, with colder cutting.<br />
