La plate-forme d'instruments de pr\u00e9cision en granit est fabriqu\u00e9e en pierre \u201cverte de Jinan\u201d de haute qualit\u00e9, par traitement m\u00e9canique et meulage manuel de pr\u00e9cision. Haute pr\u00e9cision, pas de d\u00e9formation, bonne stabilit\u00e9, longue dur\u00e9e de vie, convient aux travaux de mesure dans les usines m\u00e9caniques et les laboratoires.
\nLes principaux composants min\u00e9raux du granite \u201cJinan Qing\u201d sont le pyrox\u00e8ne, le plagioclase, la biotite et des traces de magn\u00e9tite. Il a une couleur noire, une structure pr\u00e9cise et a subi des milliards d'ann\u00e9es de vieillissement. Sa texture est uniforme, stable, solide et dure, et il peut maintenir une grande pr\u00e9cision sous de lourdes charges.
\nAvantages :
\n1. Haute pr\u00e9cision, bonne stabilit\u00e9 et r\u00e9sistance \u00e0 la d\u00e9formation, garantissant la pr\u00e9cision des mesures \u00e0 temp\u00e9rature ambiante.
\n2. Ne rouille pas, r\u00e9siste aux acides et aux alcalins, ne n\u00e9cessite pas d'entretien particulier.
\n3. Bonne r\u00e9sistance \u00e0 l'usure et longue dur\u00e9e de vie.
\n4. Les rayures et les bosses sur la surface de travail n'affectent pas la pr\u00e9cision de la mesure.
\n5. Il n'y a pas de probl\u00e8me de magn\u00e9tisation.
\n6. Glissement en douceur pendant la mesure, sans aucune lenteur
\nLa pr\u00e9cision des dalles de granit doit \u00eatre conforme aux normes des pays avanc\u00e9s et la tol\u00e9rance de plan\u00e9it\u00e9 doit \u00eatre conforme \u00e0 la norme JB\/T7975-1999.
\nNorme : Niveau 000=1 \u00d7 (1+d\/1000) um
\nNiveau 00=2 \u00d7 (1+d\/1000) um
\nNiveau 0=4 \u00d7 (1+d\/1000) um
\nNiveau 1=8 \u00d7 (1+d\/1000) um
\n(d est la diagonale en mm) (La mesure de la temp\u00e9rature se fait g\u00e9n\u00e9ralement \u00e0 20 \u00b1 2 \u2103)<\/p>\n
