Micromachining POWDER METAL

摘要

By refining its micromachining process for powder metal tool steels, this shop has reduced production costs, lead times and secondary bench work for complex tooling components. Toward the end of my recent visit to Quala-Die in Saint Marys, Pennsylvania, my host pointed to some dated EDM equipment the shop was in the process of selling. Those machines weren't being replaced by new EDM models, however. That's because Quala-Die's push to become effective at micromachining hardened tooling components used for compacting powder metal parts has greatly reduced the amount of electrical discharge machining the shop now performs.
