  • Grinding Wheel Safety: Respect The Maximum Speed

    In short, never overspeed a grinding wheel. The speed of the grinder must be compared to the speed marked on the wheel or package to make sure the machine's speed is at or below the maximum operating speed of the wheel. Surpassing this rating risks not just wheel breakage but also the safety of shop personnel.

  • Grinding wheel wear Wikipedia

    Grinding wheel wear is an important measured factor of grinding in the manufacturing process of engineered parts and tools. Grinding involves the removal process of material and modifying the surface of a workpiece to some desired finish which might otherwise be unachievable through conventional machining processes. [1]
