Cutting Tools Academia meets the shop floor to create high-performance mill
Germany’s Gühring teamed up with one of the country’s universities to develop a cutting tool for the types of hardened steels increasingly machined in mould houses.
Tool and mould houses often machine components that have been hardened so they can meet the requirements of applications and withstand processing stresses. One of the essential pre-requisites for economical hard machining is the availability of strong, wear-resistant tools with geometrically defined cutting edges.
Researchers and toolmakers team up to solve the problem
Gühring said this is why it worked with the Institute for Machine Tools and Factory Management (IWF) at the Berlin University of Technology to research practical tooling solutions.
The goal of the co-operation was to develop a fast, optimum solution that improves production efficiency, so the collaborative research focused on the examination of milling cutters for machining the hardest types of components. A contour-milling process in the form of a dry-finishing operation (edge milling) was chosen for the machining task. In addition, the project managers selected a powder-metallurgically produced high speed steel – HS6-5-3 – with an application-typical core hardness of HRC 65±3. This material represents a steel grade that is being increasingly used in the-mould making industry for hot-forging applications
