ETMM: What does Kennametal Precision Surface Solutions offer regarding PECM technology?

Matt: Depending of the region, Kennametal Precision Surface Solutions offers customers equipment (machine and specific tooling and post conditioning systems). Additionally we offer process development support and subcontract activity to support either testing, ramp up of production, and simple contract activities.

ETMM: What are the key features that drive the adoption of PECM?

Matt: Lower cost per part as a result of short cycle times, almost no electrode wear – therefore very attractive running costs. It is independent from material hardness, you can reduce process steps (shaping, surface finishing ( up to 0.05 μm ) & deburring into one operation). Freedom of design is another feature, as well as part performance, because the parts are free from any tension, and the surface generated is free from any structure.
