Patent ID: 7488239

Claim:
A device for grinding welding electrodes comprising: a driving motor; a shaft driven by said driving motor; a single grinding wheel driven by said driving motor though said shaft; a first guiding block forming a part of a motor flange comprising a rear wall adapted for engagement with a motor, a front wall separated from said rear wall by a side wall, a first depression provided at the front wall; a first and a second grinding surfaces facing opposite directions; at least one first opening passing though said first guiding block between said side wall and said first depression, 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; a space defined between said first depression of the first guiding block and said second guiding block; and wherein said first and said second grinding surfaces of said grinding wheel are positioned within said space between said first and second guiding blocks.
