Processing soft metal, use a hard grinding wheel abrasive without premature loss. Machining of hard metal, and

When the blunt abrasive off to expose the soft grinding wheel with sharp angular abrasive (ie, self-sharpening), the choicedressing roller. The former is because when the soft material of the grinding wheel work of abrasive wear is very slow and does not require premature detachment; latter

Because in grinding hard materials, abrasive wear of the grindstone faster, require faster updates.
Fine grinding, slightly harder wheel should be used in order to ensure the accuracy and roughness of grinding. The poor thermal conductivity of the workpiece material, easy

To generate burns and cracks (such as grinding carbide, etc.), the choice of the grinding wheel should be soft.Diamond Honing Stone
