Electro-chemical machining

Overview

Allows fast, stress- and burr-free machining of complex shapes regardless of material hardness giving better engine efficiency and mechanical properties and cost benefits. Produces shapes that would be impossible to achieve with conventional machining methods; allows further integration of metallic components.

Advantages

  • Complex shapes
  • High rate production
  • High material removal rates for hard metal

Used on

  • Blisks / integrated bladed rotors
  • Turbine blades
  • Outer guide vanes (OGV)
  • Diffusers
