Grinding wheels are either made of aluminum or solid steel. Straight wheel, cylinder ring, tapered type, dish cup, diamond-type, cut-off type, and type of saucer are common forms of grinding wheel. Using different bonding materials like resinoid, silicate, rubber, and metal, abrasive grains are held together in the machine. 5.

All grinding wheels have a resistance threshold. If a grinding wheel shatters when rotating, the pieces that fly off can cause serious damage. Abrasives manufacturers therefore indicate on all their wheels both maximum peripheral speed and max-imum rotational speed. These must never be exceeded. peripheral speed (m/s)2 = wheel diameter x π x 60

Classification of grinding wheels. There are many types of grinding wheels. According to the abrasives used, they can be divided into ordinary abrasives (corundum (Al2O3) and silicon carbide, etc.) and superhard abrasives (diamond and cubic boron nitride). Depending on the shape, they can be divided into cylindrical wheel, cup-shaped wheel ...

According to the different classifications of bonding agents, there are ceramic (bonding agent) grinding wheels, resin (bonding agent) grinding wheels, and rubber (bonding agent) grinding wheels. The grinding wheel is the one with the largest amount and the most widely used surface in the grinding tool. It rotates at high speed during use.

As the size of the wheel radius increases, the rim speed increases, despite the face that the motor rpm is the same. If using an oversized wheel, there is a risk that the speed at the rim (peripheral speed) and any centrifugal force becomes so great, that the wheel comes apart. Only use a grinding wheel that is designed for use at a specific RPM.

Understanding Grinding Wheel Hardness. The amount of abrasive bond in the grinding wheel determines its grade or hardness. Hardness is dependent on the grit type, the material being ground, the amount of stock removed, and a number of other factors. Hardness is rated from A-Z, with "A" being the weakest bond and "Z" being the strongest.
