ABSTRACT:
A bench-mounted sharpener apparatus for large diameter comparatively narrow width circular blades, such as a slitter blade, that includes a gear motor for turning a blade at a steady comparatively slow speed of rotation. A grinding wheel to form a precision beveled edge on one side of the blade at a time is driven at a comparatively high speed of rotation by a motor fixed to an adjustable slide which may be moved laterally, longitudinally and angularly to achieve a desired angle of bevel with precision. An adjustable blade stabilizer attached to the slide prevents flexure of the blade away from the grinding wheel during the sharpening operation by contact with the outer face of the turning blade near its periphery. A separate blade diameter sizing grinder is provided on the bench and a blade cooling liquid container is attached to the bench.
