Wheels are a blend of aluminum oxide and zirconia alumina which removes more material and lasts three times as long as our General Purpose Grinding Wheels. They are also known as Type 27 wheels raised-hub wheels and grinding discs.
The tool used for this process is the grinding wheel. It is a cutting tool in which millions of microscopic abrasive grains are bond together. Here each abrasive grain acts like a spiky tool. As shown in the image the abrasive grains are held together in the porous structure of the grinding wheel by a bonding substance bond .
Type 28 grinding wheels also known as saucer wheels have similarly depressed centers and are optimized for low grinding angles. They differ from type 27 wheels in that their concave or saucer-shaped design allows for better access to the workpiece — especially in tighter areas such as corners fillets and overhangs — and increased aggression at smaller working angles.
A grinding wheel’s durability comes from its bonded construction. 3M Grinding Wheels are built by bonding abrasive grain together with resin to create a hard durable wheel. This construction makes an abrasive wheel that lasts longer than other metal grinding solutions like flap discs and fibre discs reducing the amount of time spent changing wheels on the angle grinder.
The structure of the bonded abrasives is described in terms of proportions of abrasive phase the volume of porosity and the volume fraction of the bond as described in grinding wheels phase diagram. Each axis represents 100% of one component with the opposite side corresponding to 0% and intermediate percentages represented by the fractional distance from the side to the axis.
2 For the most common type of wheel an annular disc a predetermined amount of grinding wheel mixture is poured into a mold consisting of four pieces: a circular pin the size of the finished wheel& 39;s arbor hole its center hole ; a shell with a 1-inch 2.5-centimeter wall about twice as high as the desired grinding wheel is thick; and two flat
The blend is or grinding wheel mixture is poured in carefully predetermined amounts into four-part mold shapes: 1 a central pin provides the wheel& 39;s center hole called an "arbor hole; 2 a ...
