Additive technologies for EDM have been around since the late 1980’s. These technologies traditionally utilized silicon or chrome based additive particles in the EDM fluids to produce extremely fine surface finishes. By getting a better surface straight off the machine, secondary operations like hand polishing can be greatly reduced or eliminated. Makino’s version of this technology is called HQSF (High Quality Surface Finish). For detailed information about HQSF, click here to view my latest webinar.
During this webinar I discuss the limitations of traditional EDM processes in trying to achieve very fine finishes, and how additive technologies have aided in these applications. I also explain the differences between additive materials, discuss several HQSF applications and review some case study data that compares standard EDM to HQSF.
Also, please look out for the latest edition of EDM Today featuring Lens Tool & Mould on the cover. Based in Windsor, ON, Lens Tool has become the “go-to-guys” for all types of difficult tooling, including a variety of speaker grill molds. Thanks to their knowledge, expertise and HQSF technology, this customer has gained a reputation throughout North American as a top shop for this kind of work.
