Grinding wheels consist of two key elements: abrasive grains that perform the cutting action and an adhesion bond that holds them all together. Their hardness and strength determine what types of tasks the wheel can complete. Aluminum oxide abrasives are ideal for non-ferrous and low tensile strength materials like glass, stone and cork, while they …<\/p>\n
