Suppression des vibrations (le plus important) : Le taux d'amortissement est de 6 \u00e0 10 fois sup\u00e9rieur \u00e0 celui de la fonte, avec un taux de d\u00e9croissance 3 fois plus rapide ; la fr\u00e9quence naturelle est de 10 \u00e0 20 Hz, capable d'absorber 90% des vibrations externes, de contr\u00f4ler l'erreur de d\u00e9placement lors de la liaison dans les limites de 10 \u00e0 20 Hz. \u00b10,5\u03bcm<\/strong>.
Stabilit\u00e9 thermique : Coefficient de dilatation thermique (4-8)\u00d710-\u2076\/\u2103<\/strong> (environ 1\/20 de la fonte, 1\/6 de l'alliage d'aluminium) ; une fluctuation de 0,1\u2103 ne provoque qu'une d\u00e9formation de 0,1\u03bcm\/m, ce qui permet de maintenir une pr\u00e9cision de l'ordre du micron, m\u00eame avec un contr\u00f4le de la temp\u00e9rature de \u00b12\u2103.
Rigidit\u00e9 et r\u00e9sistance \u00e0 la charge : R\u00e9sistance \u00e0 la compression \u2265200MPa, module d'\u00e9lasticit\u00e9 45-55GPa ; peut supporter une charge de 1000kg\/m\u00b2 sans d\u00e9formation, convient aux charges lourdes \u00e0 cinq axes (axe unique > 200kg).
R\u00e9tention de la pr\u00e9cision : R\u00e9sistant \u00e0 l'usure, \u00e0 la corrosion et sans contrainte interne, avec une d\u00e9rive de la pr\u00e9cision g\u00e9om\u00e9trique \u00e0 long terme <1\u03bcm\/an.<\/p>\n\n\n\n
II. Structure et disposition typiques

Mat\u00e9riau : Vert de Jinan \/ Noir de Zhangqiu (naturel) ou fonte min\u00e9rale (artificiel), caract\u00e9ris\u00e9 par un grand bloc global avec des fentes, des manchons en acier pr\u00e9-encastr\u00e9s \/ des surfaces de montage des rails de guidage.
Disposition : Structure en forme de T, rails de guidage des axes X\/Z dispos\u00e9s verticalement, axe Y sur l'axe X et axes rotatifs (B\/C) int\u00e9gr\u00e9s dans le chariot Y.<\/p>\n\n\n\n
Syst\u00e8me de support et d'isolation des vibrations
Support \u00e0 quatre points : Les points d'appui sont externes \u00e0 la base (grandes machines) ou internes (petites et moyennes machines), \u00e9quip\u00e9s de ressorts pneumatiques \/ de coussins d'air antivibrations pour isoler les vibrations du sol.
Mise \u00e0 niveau : Pieds de nivellement r\u00e9glables avec pr\u00e9cision, avec une pr\u00e9cision horizontale \u22640,02mm\/m.
Structures des sc\u00e9narios d'application
Usinage ultra-pr\u00e9cis sur cinq axes (par exemple, Precitech Freeform L) : Base en granit naturel scell\u00e9e, isolation des vibrations TMC MaxDamp int\u00e9gr\u00e9e, adapt\u00e9e au tournage au diamant et au micro-fraisage.
Aff\u00fbteuse d'outils domestique \u00e0 cinq axes (par exemple, KToolG3515) : Corps de lit int\u00e9gr\u00e9 en granit artificiel, amortissement \u00e9lev\u00e9, faible dilatation thermique, adapt\u00e9 \u00e0 l'aff\u00fbtage d'outils en carbure de ciment \/ diamant.<\/p>\n\n\n\n
III. Prise de vue r\u00e9elle de l'atelier (vue \u00e0 longue distance d'un atelier spacieux)
Sc\u00e8ne : Grand atelier \u00e0 temp\u00e9rature constante (\u00b10,5\u2103), sol en \u00e9poxy, plusieurs machines \u00e0 cinq axes avec des bases en granit align\u00e9es, espace ouvert et lumi\u00e8re vive.<\/p>\n\n\n\n
IV. Points cl\u00e9s de la s\u00e9lection Granite base for five-axis ultra-precision machine tools, featuring a core made of natural granite (Jinan Green \/ Zhangqiu Black) or artificial mineral casting to form an integrated bed body. This achieves high damping vibration reduction, low thermal expansion stability, and high rigidity load-bearing, serving as the foundation for micron\/sub-micron level five-axis linkage. I.
