08/09/10 - Grinding of Cutting Edges

Electropolishing using POLIGRAT processes is an efficient and cost-effective procedure for the electrochemical grinding and fine deburring of metal blades.

Mechanical grinding damages cutting edges through pressure and temperature. The result is deformation, structural damage and the formation of burrs. The edges and sides of the blades consequently fail to demonstrate the optimal degree of sharpness and smoothness.

Electropolishing as the last work step after the formative grinding smooths, deburrs and sharpens cutting edges and sides in a single operation without stressing the material either mechanically or thermically. Burrs and thermically damaged areas are removed without deforming the blade. The cutting edges are extremely sharp, and through the smoothing of the sides the friction and thus the cutting forces required are considerably reduced. A "breaking in" is no longer necessary.

Electropolishing is effective irrespective of the form of the blade, and thus is also suitable for the processing of complex geometries, even three-dimensional ones such as serrated edges or punching tools. The areas of application extend from scalpels and hypodermic needles to knife blades, razor blades, chopping knives in food processors and machine knives to cutting tools such as milling cutters, drills and saw blades. Electropolishing before coating with carbide metal results in stable edges and prevents the partial breaking out of the edges under stress.

As a result of the structure resulting from the electropolishing, carbide metals cannot be sharpened formatively, but the edges can be finely deburred.
