CA 2431110
Improvements in material-to-material connections are provided. For example, metal-to-metal connections are improved, such as the interface connection between a dental handpiece bur tube (10) and a component such as bearing (12). At least one marking, such as a laser marking (20) is provided such that an amount of excavate material (21) is excavated from the marking (20). When a component such as a bearing (12) is positioned upon the bur tube (10), a portion of the excavate material (21) is physically impinged between the two components (10, 12) filling any spaces or gaps therebetween.
L'invention concerne des amélioration apportées à des liaisons matière-matière. Par exemple, des liaisons métal-métal sont améliorées, telles que la liaison d'interface entre un tube (10) de fraise à main de dentisterie et un composant, tel qu'un support (12). Au moins une marque, telle qu'une marque au laser (20) est formée, de sorte qu'une certaine quantité du matériau à excaver soit excavée de l'endroit correspondant à la marque (20). Lorsqu'un composant, tel qu'un support (12) est placé sur le tube (10) de fraise, une partie du matériau à excaver (21) vient heurter physiquement les deux composants (10, 12) remplissant les espaces entre eux, quels qu'ils soient.
