Grinding device for chain saws, where the saw chain is sharpened b pressing an abrasive block (15) against the top side of the cutter links (11) when the saw chain is running around a rim type sprocket (14) and the generally cylindrical periphery of the drive sprocket has raised steps or ramps (17, 27) which lift the front end of the cutter links, thereby allowing a sufficiently large cutting depth without locating the depth gauge far in front of the front rivet. This reduces vibrations and instabilities of the saw chain when sawing. |
