Bench and pedestal grinding wheels are used for sharpening, shaping and deburring parts and tools. Bench grinding wheels are generally used on stone and metal materials. Choose a category below for the right bench grinder wheels for your applications.
Choosing the correct abrasive material for your surface can shorten grinding time, reduce cost and prevent premature wear. Aluminum oxide, for example, is a great all-around abrasive material, while diamond is used on specific materials like ceramic.
Aluminum oxide is the most commonly used abrasive. Best-suited for general purpose deburring and blending, it is tough, economical and fracture-resistant. Commonly used on ferrous alloys, high-tensile materials, and wood.
Use larger grits/coarser grades for removing more material over a larger contact area. Use smaller grits/finer grades where the final finish is important.
The wheel hardness is designated on a scale ranging from A (very soft) to Z (very hard). The type and amount of bonding material determines the hardness rating.
The bond of the grinding wheel is the material which holds the abrasive grains. As the wheel is used, the bonding material wears and exposes new abrasive grains.
Vitrified bonds are made from a mixture of clays fused at high temperatures, creating a glass bond.
Grain Structure
Grain structure is designated on a scale ranging from 0 (dense) to 16 (open). Dense grain structures have grains that are close together and generate a consistent finish. Open grain structures have grains that are spaced apart for faster stock removal.
Porous wheels are specialized for fast and cool cutting of hardened tool steels. They have extra-wide grain spacing, which increases the flow of coolant and improves chip removal. While this helps reduce heat and loading, it can shorten wheel life.
