Abstract

Se describe una herramienta adiamantada del tipo de segmento, es utilizada para cortar, perforar sustancias quebradizas, tales como piedras, ladrillos, estructuras de hormigon, o estructuras de asfalto. En la herramienta adiamantada, los segmentos se establecen cada uno con diamantes en una estructura de una sola capa o una estructura de capas multiples y se arregla alternativa o intermitentemente en un alma de acero, diferente de las herramientas adiamantadas convencionales que tiene segmentos establecido aleatoriamente con diamantes. Tal arreglo adiamantado de esta invencion permite que los diamantes realicen mas efectivamente su accion de corte, y de manera que la herramienta adiamantada tiene una velocidad de corte incrementada, ademas de reducir la cantidad de restos finos generados durante un proceso de corte o perforado para afectar la salud del trabajador o provocar contaminacion ambiental. Los segmentos, cada uno se establece con diamantes en la estructura de una sola capa o de capas multiples, el arreglo adiamantado se define para que los diamantes de cada segmento posterior formen muescas en la superficie de una sustancia quebradiza a lo largo de las partes planas entre las ranuras previamente formadas en la superficie de la sustancia quebradiza por los diamantes de un segmento anterior.
