Sažetak
There is a strong interest both in mining and quarrying industry for the development of mechanical components such as jaws and mills made of high wear resistance materials. Hadfield steel is particularly resistant to abrasion wear and it is suitable for such an application. In recent years, a new metallurgical procedure has enabled the production of Hadfield steel with dispersion of Ti(C, N), which further increases the wear resistance of the material but severely reduces its machinability. In this work, a comparison of commercial tool grades and geometries for machining special Hadfield steel is presented. Specifically, surface roughness, chip form and tool life obtained by applying the selected tools were investigated and discussed. Some suggestions for tool selection are finally presented.
