As grinding proceeds the power drops slowly as the grits sharpen and fall out and surface finish gradually worsens. Eventually the finish approaches the roughness limit and you have to dress.

  • How to Select the Right Flap Disc for Your Project

    For instance grinding wheels have to be discarded even after a small area of abrasive is worn out. Comparatively flap discs remain useful even after the flaps erode which results in a longer operating life. Compared to a flap disc grinding wheels are cheaper on a unit cost basis. 2004. A. My experience is the bonded abrasive (grinding wheel) composition may be compromised by the heat generated by a "clogged" wheel. The heat is usually carried away from the wheel in the metal it removes but a clogged wheel becomes a heat generator and the metal adhered to the wheel seals the heat in therefore you could see a wheel explosion when the material is in contact with the wheel.
