I. Mat\u00e9riaux et performances de base
\nPierre s\u00e9lectionn\u00e9e : granit noir de haute qualit\u00e9 repr\u00e9sent\u00e9 par **Jinan Green (G3701)**, avec un vieillissement suffisant et un stress r\u00e9siduel extr\u00eamement faible ; duret\u00e9 Mohs 6-7, densit\u00e9 2,65-2,8g\/cm\u00b3, absorption d'eau 0,1% ; coefficient de dilatation lin\u00e9aire d'environ 4,6\u00d710-\u2076\/\u2103, seulement la moiti\u00e9 de celui de l'acier, r\u00e9sultant en pratiquement aucun gauchissement local sous une temp\u00e9rature uniforme ; non magn\u00e9tique, r\u00e9sistant \u00e0 la corrosion acide et alcaline, et ne n\u00e9cessitant pas de traitement antirouille.<\/p>\n

Avantages des performances de base
\nAmortissement \u00e9lev\u00e9 R\u00e9duction des vibrations : La performance d'amortissement des vibrations est 5 \u00e0 10 fois sup\u00e9rieure \u00e0 celle de la fonte, ce qui permet de supprimer efficacement la r\u00e9sonance de l'\u00e9quipement et les interf\u00e9rences de vibrations externes ;
\nStabilit\u00e9 de la pr\u00e9cision \u00e0 long terme : Aucune r\u00e9vision ou \u00e9talonnage majeur n'est n\u00e9cessaire pendant 5 \u00e0 8 ans ou plus, ce qui d\u00e9passe de loin les bases m\u00e9talliques ;
\nQualit\u00e9 de la surface : Apr\u00e8s le rodage manuel de pr\u00e9cision au diamant, la rugosit\u00e9 de surface peut atteindre Ra0,02\u03bcm, et la plan\u00e9it\u00e9 des petites sp\u00e9cifications peut atteindre 1,5\u03bcm pour le grade 000.<\/p>\n

Limites : Grande fragilit\u00e9 et faible r\u00e9sistance aux chocs ; la manipulation brutale est strictement interdite ; les r\u00e9parations ne peuvent pas \u00eatre soud\u00e9es et les dommages graves n\u00e9cessitent un remplacement complet ; long d\u00e9lai d'ex\u00e9cution pour les pi\u00e8ces sur mesure et co\u00fbt d'achat initial plus \u00e9lev\u00e9 que celui des pi\u00e8ces sur mesure.<\/p>","protected":false},"excerpt":{"rendered":"\n\n\n\n\n\n\n\n\n\n\n\n
