Abstract

L'invention concerne une machine à rainurer par traceur PCD de type conique, montée dans une découpeuse ayant un élément de retenue pour traceur de type conique. Pour faciliter la découpe de différentes pièces à travailler non métalliques, du type verre et TFT-LCD, on utilise la machine afin de tracer une ligne, à savoir une ligne de découpe, sur les pièces, puis un appareil à découper les rainures selon un procédé correspondant. Le traceur (1) forme des surfaces coniques intégrées sur les deux côtés extérieurs des bordures de la ligne de découpe, et en particulier les rainures de découpe sont formées à intervalles constants et suivant une profondeur constante sur la ligne de découpe, au moyen d'un appareil à découper les rainures par usinage du type à décharge électrique. On définit ainsi une pression par unité de surface de la ligne de découpe, et la pression est transmise à la pièce, et il est possible d'augmenter la pression afin que différentes fissures verticales plus profondes apparaissent lorsque le diamètre externe de la ligne est réduit et que la pression de découpe ne varie pas. On fait apparaître facilement des fissures verticales profondes en appliquant une pression modeste et on réduit au minimum l'apparition de fissures horizontales sur la pièce durant le processus de traçage, ce qui permet ensuite de désolidariser la pièce selon une surface de découpe complète et nette, sans production de morceaux (copeaux) continus/non continus, au moment de la découpe de la pièce. Il en résulte une amélioration de la productivité et de la qualité.
