To be able to properly prepare edges for the work they must do, we must be able to measure a very small radius, some specialized measuring devices are used. Fullerton Tool can put a radius on a cutting edge and accurately measure down to about 4 microns (about .00016 inches). For reference, a human hair is about 75 microns in diameter. With innovation in materials, today and manufacturers expect very high-performance results from their cutting tools to compete globally. Edge prep has helped push cutting tools to the next level. As you would guess edge prep for aluminum is a bit different than that for steel, cast iron, composites, etc. At Fullerton, we consider edge prep as important as coatings and they are the basis for high-performance cutting tools and increased productivity and performance for general purpose cutting tools. Our experts are working hard to keep our cutters working hard for you. If you have an application where you don't think you are getting all you can from your carbide tooling, contact our Fullerton team to see what we can do to help improve your processes.
