Understanding Grinding Wheel Hardness Sparky Abrasives

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.

Hardness Klingspor Abrasive Technology

The hardness of a grinding disc is the resistance that the binding of the disc exerts against grain shedding. The bond hardness of a cutting-off wheel or grinding disc can be influenced and adjusted by the resin used as well as by the added filler materials. According to DIN ISO 525 the bond hardness of cutting-off wheels and grinding discs is identified by letters of the alphabet that are added to the type

Reade Advanced Materials Mohs Hardness Typical Of

A material graded 8 to 16 mesh is very coarse and is used for hard-to-clean surfaces or surfaces that require a deep anchor pattern. A material graded 20 to 40 mesh is considered a general-purpose abrasive. Eighty to 120 mesh is considered fine and is used for polishing surfaces. Round or spherical abrasives are graded by particle diameter.
