 <\/p>\n

Une couronne diamant\u00e9e<\/strong> se compose principalment de deux \u00e9lements: le tube en acier avec sa bague de fixation et les segments diamant\u00e9s (m\u00e9lange de diamants et liant).<\/p>\n

Elles peuvent avoir une soudure en argent, soudure par d\u00e9pression, ou un apport de fil d’argent \u00e0 la soudure qui unit les deux parties, en restant solidement unis. Ou bien encore, une soudure laser, la plus s\u00fbre des soudures en plus d’\u00eatre la plus pr\u00e9cise. Celle-ci est r\u00e9alis\u00e9e avec la technologie la plus avanc\u00e9e, qui requiert une grande qualit\u00e9 des mat\u00e9riaux autant pour le segment que pour la planche.<\/p>\n

La perforation avec diamant permet de r\u00e9aliser des carrotages de dimensions tr\u00e8s precises et sans \u00e9clats. Cette perforation peut \u00eatre faite de mani\u00e8re verticale, horizontale et inclin\u00e9e et aussi de permettre de r\u00e9duire le temps de carrotage.<\/p>\n

La perforation avec diamant \u00e0 sec ou \u00e0 eau d\u00e9pend du type de mat\u00e9riau et de la profondeur et de celui-ci. Dans des mat\u00e9riaux comme le b\u00e9ton (arm\u00e9 ou non), on utilise de l’eau, et sur les mat\u00e9riaux tendres comme la brique ou les blocs on obtient un bon r\u00e9sultat.<\/p>\n

Pour de petits carrotages, il est possible de perforer \u00e0 sec. A l’inverse, pour des carrotages plus importants, il convient de les r\u00e9aliser \u00e0 l’eau. Les travaux sans eau risque d’ab\u00eemer le segment tr\u00e8s rapidement. \u00c0 l’inverse, l’exc\u00e8s d’eau peut diminuer la vitesse de perforation.<\/p>\n

 <\/p>\n

Applications.<\/strong><\/h4>\n
    \n
  • Carrotage intensif du b\u00e9ton vieux ou arm\u00e9 m\u00eame \u00e0 forte abrasivit\u00e9.<\/li>\n
  • Passage des tuyauteries (eau, gaz, \u00e9lectricit\u00e9), tout type d’ouverture circulaire comme la climatisation, la mise en place de cadres \u00e9lectriques, l’ ouverture de portes et fen\u00eatres, l’ extraction de t\u00e9moins (b\u00e9ton, asphalte), l’extraction de gaz ou de prise d’air.<\/li>\n
  • Bon rendement pour carrotage sur asphalte.<\/li>\n<\/ul>\n
