Abstract

La présente invention porte sur un dispositif de polissage de surface et, plus particulièrement, sur une technologie pour réduire à un minimum la dispersion de poudre métallique, qui est générée par la surface d'un objet métallique traité, sans avoir fondamentalement un dispositif d'admission d'air ou un dispositif de captage de poussière séparé pendant un processus de polissage de surface, et dans lequel des particules de polissage de métal sont éjectées vers la surface de l'objet métallique à traiter, empêchant ainsi une pollution de l'atmosphère ambiante et simplifiant l'installation globale. Par ailleurs, la présente invention a pour but de fournir un dispositif de polissage de surface qui utilise un déchet, qui est généré pendant un processus de fusion, par exemple comme particules de polissage, de telle sorte que la fonction de prévention de dispersion de poussière est présentée, contribuant ainsi à une économie de ressources.
