BONDED ABRASIVES 101
Bonded abrasives come in a variety of grains, grit sizes, bonding compositions, sizes & shapes.
They consist of a mixture of abrasive grains, fillers, and bonding materials.
Bonding agents can be resin, rubber, shellac, epoxy, magnesite, or plastic.
As the wheel spins against the surface of a work piece, the grains fracture and wear away. As the top layer wears, a new layer of grains is exposed, as the wheel continues to shrink in diameter.
Throughout the industry, many developments have been made using new types of abrasive grain and bonds to increase the performance. Each product is designed to give a specific finish, speed of cutting, and stock removal or cutting requirements.
The bonding compositions determine working characteristics. Softer bonds are referred to as fast cut, due to wear rates that quickly expose new grains. Harder bonds are called long life, making the wheels more durable.
Contamination-free bonds are available for stainless steel applications.
Resin-bonded products are used for a wide range of applications, ranging from the tool room, foundry floor, or the job site. These include common products such as grinding discs, grinding wheels, cut-off wheels, and mounted points.
Vitrified wheels and segments are used in the tool rooms with production surface grinders or center-less machines.
