Machining Hardened Steel

Many shops have implemented hard milling through high speed machining as a way to generate intricate die and mold forms on the machining center with less need for edm and hand finishing.

Machining hardened steel.

There are several components of the process which include. First choice cbn grade designed to deliver stable and predictable tool life while machining case and induction hardened steels with light to medium interrupted cuts chamfered component edges. The effective utilization of the. If a somewhat larger amount of money is available to be spent on cutting materials the evolution metal cutting saw is a fast and efficient tool that will cut through hardened steel with relative ease making clean cuts and retaining the hardness of the steel.

High speed milling of hardened die steels was second choice at 49 percent. 1 the following observations from the engineering research center for net shape manufacturing erc nsm at the ohio state university may be useful to shops contemplating getting into high speed milling. First choice for external and internal machining of small and slender components. Many plants that manufacture hardened steel bearings gears and axle shafts use this process.

Typical materials that are hard turned are 5120 steel 62 rc 1050 steel 62 rc 9310 60 rc and 4320 steel 60 62 rc. Since then it has gained more acceptance in the industry. High speed machining hsm of hardened die steels should not be feared but embraced.
