Abstract
In order that bar-shaped cutters can be ground as accurately as possible, it is essential that the bar-shaped cutters are clamped as close as possible to the surfaces which are to be ground. For this purpose, each bar-shaped cutter is pressed against two stop faces or surfaces by means of two claws of a clamping lever, and the one claw which is closer to the surface to be ground is structured to be more elastic or resilient than the other claw. Particularly, the claw closer to the surface which is to be ground is more intensely pressed or forced against the bar-shaped cutter than the other claw.
