WORK-PART MATERIALS

The metal cutting industry produces an extremely wide variety of components machined from many different materials. Each material has its own unique characteristics that are influenced by the alloying elements, heat treatment, hardness, etc. These combine to strongly influence the choice of cutting tool geometry, grade and cutting data. Therefore, work-piece materials have been divided into six major groups, in accordance with the ISO-standard, and each group has unique properties regarding machinability (ISO DIN 513):

ISO - P:

Steel is the largest material group in the metal cutting area, ranging from unalloyed to high-alloyed material, including steel castings and ferritic and martensitic stainless steels. The machinability is normally good, but differs a lot depending on material hardness, carbon content, etc. This group includes long-chipping ferrous metals except stainless and austenitic steels and is, according to the cutting load, divided into the application groups 01-50.
