PROCESSO PARA O ACABAMENTO DE SUPERFICIES DE UMA PECA DE FERRO FUNDIDO CONTENDO CARBONO BEM COMO DISPOSITIVO PARA A REALIZACAO DO PROCESSO E CILINDRO DE FERRO FUNDIDO CINZENTO |
摘要 |
The invention relates to a method and an apparatus for the treatment of surfaces of a workpiece of carbon-containing cast iron, and in particular of blind holes in gray iron cast workpieces, by electrochemical stock removal and mechanical reaming-and-plating. Electrochemical stock removal and mechanical reaming and plating are carried out in separate steps whose operating parameters are independently adjustable, the mechanical stock removal being essentially confined to a reaming-and-plating of the surface which does not entail a closing of graphite flakes. A cylinder bore produced by the method of the invention with desired roughness will have a dark, lustrous surface. |
