The double-disc straight-groove (DDSG) grinding method is a new precision machining approach employed for the rolling surface of bearing rollers. The friction coefficient and wear resistance of grinding disc materials affect the grinding performance due to the operation on the workpiece. However, relevant research on DDSG is rather limited currently. Therefore, …

On grinding machines, this is usually accomplished by dressing the wheel, but for virtually all other abrasives this is not an option. Abrasive manufacturers have made great efforts to make their products "friable" or semi-friable, which means the abrasive breaks away when dull, bringing fresh material to bear.
