ABSTRACT:
A device for grinding welding electrodes comprises a driving motor, a shaft driven by said driving motor and a grinding wheel driven by said driving motor through said shaft, said grinding wheel having a first and a second grinding surface. A first guiding block is provided having at least one first opening, said first opening defining a position relative to said first grinding surface and said opening being adapted to guide a welding electrode for grinding into said defined position relative to said first grinding surface, and a second guiding block having at least one second opening, said second opening defining a position relative to said second grinding surface and said second opening being adapted to guide a welding electrode for grinding into said defined position relative to said second grinding surface.
