Outline
Electron beam machining is the technology to use energy produced by forming argon gas stored in the vacuum chamber into plasma and to generate a "high power electron beam of a pulse shape in a large area" to melt the metal surface. The uneven surface is made flat by the repeated fusion and coagulation by heat and surface tension.

Effects
With EDMing, the residual gases left in the material are eliminated which results in a flat surface. Sodick EDM with the advanced SVC circuit(Finish circuit) ensures an even flat surface(before EBMing), resulting later in an ideal surface for Electron Beam machining. The EBM process provides excellent corrosion, friction, and water resistant surface, which is ideal for mold surfaces.

Main Features

Improvement of surface finish

A short-time processing of EBM remarkably improves the surface finish of electrical discharge machining.
EBM is effective also in removing the cutter mark of a milled surface.

EDMed surface	EDMed + EBMed surface
(Surface finish : 0.94 µm to 0.26 µm Ra)

Milled surface	Milled + EBMed surface
(Surface finish : 0.1 µm to 0.06 µm Ra)

Improvement of surface quality

Comparison of corrosion resistance

Corrosion resistance test with salt spray (condition: 5%-NaCl, 60°C, 48h)

Rusted by salt spray

Corrosion resistance improved through EBM finishing

Improvement in surface quality (corrosion resistance, water-repellence, etc.)

Improved release of moldwith less remnant clogging.
Easier release of plastic forming molds, resulting in shorter forming time.
