Superfinishing Sharpening Process

Valley Grinding uses a superfinishing process to sharpen/resharpening all circular knives. Superfinishing produces the cleanest, sharpest cutting edge possible. First, worn stock is removed with a traverse-type grinder. This technique helps maintain the molecular integrity of the steel. The result is a better finish on the sharpened blade. Next, the blade goes to the superfinisher where the burr is mechanically removed and the edge is polished. The result is a razor-sharp blade edge free of burrs that will improve cut quality, reduce maintenance costs and provide continuous improvement of your slitting operation.

To find out more about superfinishing, or sharpening slitter knives and blades, give Valley Grinding a call today at 800.950.7575!
