Dressless regeneration of grindactivity in dry grinding of carbon

1^st report: Proposal for removing loaded chips with adhesive tape and removal characteristics

Abstract

Dressing is frequently carried out in dry grinding of hard carbon because of loading over short grinding times. However, even if abrasive grains covered with loading chips on a wheel surface still have sharp cutting edges, they are removed with loaded chips by dressing. In this study, we propose the dressless restoration of grindactivity in which loaded chips are removed by peeling off the adhesive tape from the loaded wheel surface after pressing. The process of removing loaded chips in dressless restoration was clarified, and the effects of adhesive tape pressing load and peeling speed on removal characteristics of loaded chips were investigated.
