As one of the most common machining processes in the industry, Shape-Master Tool’s PCBN turning inserts come in all available ANSI and ISO insert designations. Workpiece material and severity of the cut are all taken into account as we select the CBN grade for your application. Dimensional tolerances and surface roughness are both influenced by the edge preparation and geometries we apply. CBN segment sizes are available to cover DOC requirements ranging from light finishing to heavy roughing passes.
