Tout d'abord, parlons de l'usure normale. Voici quelques cas d'usure normale.<\/p>\n<ul>\n<li>En ce qui concerne le frottement entre les pi\u00e8ces \u00e0 usiner, il convient de veiller \u00e0 ce que les pi\u00e8ces soient suffisamment nettoy\u00e9es et lubrifi\u00e9es.<\/li>\n<li>En ce qui concerne l'usure caus\u00e9e par des particules dures, il convient d'\u00e9viter d'exposer les pi\u00e8ces et de veiller \u00e0 ce qu'elles soient nettoy\u00e9es et recouvertes.<\/li>\n<li>Pour l'usure caus\u00e9e par une charge altern\u00e9e \u00e0 long terme, il convient de choisir une huile de lubrification appropri\u00e9e afin de r\u00e9duire les vibrations suppl\u00e9mentaires du syst\u00e8me et d'am\u00e9liorer la pr\u00e9cision d'usinage des pi\u00e8ces.<\/li>\n<li>En ce qui concerne la corrosion chimique des pi\u00e8ces, nous devons \u00e9liminer les produits chimiques nocifs et am\u00e9liorer l'anticorrosion des pi\u00e8ces.<\/li>\n<li>En ce qui concerne les modifications de la structure m\u00e9tallographique ou l'adaptation des pi\u00e8ces \u00e0 des temp\u00e9ratures \u00e9lev\u00e9es, il convient de s'efforcer d'am\u00e9liorer les conditions de travail ou d'utiliser des mat\u00e9riaux r\u00e9sistants aux temp\u00e9ratures \u00e9lev\u00e9es et \u00e0 l'usure pour l'usinage des pi\u00e8ces.<\/li>\n<\/ul>\n<p style=\"text-align: left;\"><a href=\"http:\/\/www.symachining.com\/wp-content\/uploads\/2018\/08\/machining-parts.jpg\" rel=\"attachment wp-att-1209\"><img decoding=\"async\" class=\"aligncenter wp-image-1209 size-full\" src=\"http:\/\/www.symachining.com\/wp-content\/uploads\/2018\/08\/machining-parts.jpg\" alt=\"machining parts\" width=\"553\" height=\"458\" \/><\/a><br \/>\nEnsuite, parlons de l'usure anormale. L'usure anormale peut avoir plusieurs causes. La r\u00e9paration ou l'usinage ne r\u00e9pond pas aux exigences de la conception, la violation des proc\u00e9dures d'exploitation et un transport, une manipulation et un stockage inad\u00e9quats. Pour \u00e9viter ce type d'usure, il convient de v\u00e9rifier rigoureusement la qualit\u00e9 du produit, de se familiariser avec ses propri\u00e9t\u00e9s m\u00e9caniques, de l'utiliser avec pr\u00e9caution et de ma\u00eetriser suffisamment de connaissances en mati\u00e8re de levage.<\/p>\n<p>La d\u00e9formation de la pi\u00e8ce de base modifie la position relative de chaque pi\u00e8ce, ce qui acc\u00e9l\u00e8re l'usure de la pi\u00e8ce.<br \/>\net de raccourcir la dur\u00e9e de vie de la pi\u00e8ce. Nous pouvons prendre des mesures raisonnables d'installation et d'ajustement afin d'\u00e9viter les probl\u00e8mes d'usure.<br \/>\nl'apparition de d\u00e9formations. L'endommagement de l'\u00e9quilibre des pi\u00e8ces fait r\u00e9f\u00e9rence au d\u00e9s\u00e9quilibre des pi\u00e8ces tournant \u00e0 grande vitesse. Sous l'action de la force centrifuge, la d\u00e9t\u00e9rioration des pi\u00e8ces est acc\u00e9l\u00e9r\u00e9e et leur dur\u00e9e de vie est r\u00e9duite. Nous devrions adopter un test d'\u00e9quilibre pour la pr\u00e9vention. La pi\u00e8ce de rechange n'effectue pas de rodage en surface, ce qui augmente l'usure. Il faut donc proc\u00e9der \u00e0 un rodage. Les pi\u00e8ces r\u00e9par\u00e9es ne sont pas correctement s\u00e9lectionn\u00e9es en ce qui concerne le mat\u00e9riau, la duret\u00e9 de la surface n'est pas conforme aux normes et le traitement thermique n'est pas qualifi\u00e9. Il convient donc de s\u00e9lectionner les mat\u00e9riaux en fonction des besoins et de proc\u00e9der \u00e0 un traitement thermique raisonnable.<\/p>\n<p>Pour en savoir plus sur le choix des mat\u00e9riaux, consultez les articles ci-dessous.<\/p>\n<p><a href=\"http:\/\/www.symachining.com\/fr\/choosing-right-material-aluminium-machined-parts\/\" target=\"_blank\">Comment choisir l'aluminium pour vos pi\u00e8ces d'usinage ?<\/a><\/p>","protected":false},"excerpt":{"rendered":"<p>Dans le domaine de l'usinage, l'usure des pi\u00e8ces usin\u00e9es est un ph\u00e9nom\u00e8ne courant, qui peut \u00eatre caus\u00e9 par divers facteurs tels que le mat\u00e9riau de la pi\u00e8ce, l'environnement et les m\u00e9thodes de traitement.
