Abstract
The method is for sharpening a blade. An automatic sharpening apparatus is provided that has a holder. A blade is placed into the holder. A grinding-wheel driving motor, in operative engagement with a wheel on a spindle, rotates a grinding wheel. A grinding assembly motor moves the grinding wheel in an x-direction towards the blade. A linear motor moves the grinding wheel from a first position to a second position in a z-direction without moving the grinding-wheel driving motor. The rotating grinding wheel engages the blade. The grinding wheel sharpens the blade.
