A year ago, WidiaValenite introduced multilayer chemical vapor deposition (MLCVD) technology, which bring into views extremely thin layers of coating material upon an insert substrate. In pre-introduction testing, the first MLCVD milling grade, SM245 performed well above a wide variety of workpiece materials and milling operations. Since then, however, MLCVD inserts have proven themselves in production applications, extending tool life as abundant as ...
