Abstract (en)
[origin: EP0864384A2] A process for cutting metallic pieces with a high degree of precision and surface finishing from a continuous material or cut-down sizes inserted into a die between a matrix (12) and a punch (13) interacting between each other, comprising: a first cutting phase in which a piece (10) is separated from a scrap or other piece (11) opposite a surface having a mixed profile; a second cutting phase of said piece (10) opposite said surface having a mixed profile (15, 16, 17), so as to achieve a smooth finished surface (21). <IMAGE>
