Abstract
A sharpening apparatus for a rotating blade is configured such that a rod-shaped grinding tool or a conical cutting-edge surface is movable in the transverse direction. This carried out by a parallelogram linkage. The grinding tool is pressed by a weight under constant contact pressure against the front cutting surface.
Claims12
An apparatus for sharpening rotating blades which have a cutting edge running in the circumferential direction and bounded by a rear cutting-edge surface and a front conical cutting-edge surface running in a manner inclined with respect to the rear cutting-edge surface, comprising:
- a blade carrying part, to which a rotating blade can be fastened and by which the rotating blade is rotated;
- a grinding head for regrinding the front conical cutting-edge surface, which has a rotating cutting tool,
- wherein the relative position between the grinding head with respect to the rotating blade is chosen such that the location of engagement between the rotating cutting tool and rotating blade travels in a direction of an axis of the grinding tool on its lateral surface in dependence on the angular position of the rotating blade.
