What is the metamorphic layer?
Line cutting using instantaneous discharge energy thermal effect of the workpiece material melting, evaporation up to size requirements processing because the line cutting working fluid with a dielectric effect of liquid processing with the electrolysis of the role of cutting the thermal effect of electrolysis through the processing of the surface thickness of the surface layer
Is the phenomenon of micro-cracks, etc. lead to wire cutting mold prone to early wear and tear directly affect the mold blanking gap to maintain and mold edge easy to collapse to shorten the mold life
In the carbon steel that the surface of the workpiece melting layer (the stratified layer by the melting of the solidification layer and the heat affected layer group) metallographic photographs show white white layer and the base metal exactly the same kind of dendritic quenching casting organization and the inner layer is very strong by the martensite
