Notes
- Large improvements in cutting tool design and technology have been achieved in the last decades. But the problem of improving the tool body material is not adequately studied. In the present study, the different aspects associated with the steel properties as related to the milling cutter body application are reviewed. The working performance of a tool holder depends in particular on the fatigue strength, high temperature properties and machinability of the tool steel used. Rotating tools, tool going in and out of cutting engagement, impose dynamic stresses and require adequate fatigue strength off the tool. Different publications, as well as internal investigation at Uddeholm Tooling AB show that the working temperatures of milling cutter bodies in the insert pocket vary from 300 to 600 degrees Celsius depending on the cutting conditions and material of the workpiece. As a result, steel for this application needs good hot properties such as high temper resistance, high hot hardness values, etc. Machinability is also essential as machining of steel represents a large fraction of the production cost of a milling cutter. Its complex shape with flutes and insert pockets as well as small thread holes and small deep holes for cooling channels require time consuming and advanced machining operations. The essential properties mentioned above were characterized with the emphasis to the steel type, its microstructure and purity, processing and surface treatment and strong interrelations between them.
