Influência da Dureza dos Discos Abrasivos no Corte de Materiais Dúcteis

Abstract: RESUMOO corte de materiais por disco abrasivo é um dos processos que apresentam as melhores características de economia, eficiência e rapidez sendo muito utilizado no meio industrial. Fatores como porcentagens e homogeneidade da mistura dos componentes, tamanho, forma (abrasividade), tenacidade e dureza dos grãos abrasivos, tipos de ligantes e de abrasivos, velocidade de corte e velocidade de mergulho influenciam na segurança, no desempenho e comportamento da operação.Este trabalho apresenta um estudo sobre a … Show more

“…After 12 cuts per disc, results showed that PE and TB discs removed the highest volume, followed by SP and DE discs. In contrast with [5], wear indicator G-ratio showed noticeable differences. The highest material removal ability relative to wear was PE disc followed by SP disc.…”

“…In addition, Bianchi et al [5] evaluated the incidence of binder hardness on cutting force and the G-ratio (volume of material removed per unit of volume of wheel wear) using abrasive discs with three different hardness values, finding a light increase of cutting force with hardness, whereas there were no differences with respect to G-ratio; the little increase in cutting force should have needed further experiments.…”

“…Conforme BIANCHI et al [5], nos processos de corte com disco abrasivo, a dureza da matriz é uma variável muito importante sobre sua vida útil, sendo determinante na quantidade de material a ser removido [6]. Assim, um disco com maior dureza tende a reter mais o grão abrasivo.…”
