Steel is one of the most popular engineering materials used in industries. However, cutting steel directly with a diamond cutter causes severe tool wear. Various approaches have been investigated to improve the tool life and surface finish of the work piece. This includes cryogenic cooling, application of carbon-rich gas and […]

The low frequency waves observed on optical inserts which cause color separation on image had been eliminated by ruling, a post diamond turning process, which Delta Optics had developed! The charts below illustrate profile found on diamond turned hardened steel inserts before ruling (~30 nm) amplitude and after ruling. A […]
