Couleurs fonc\u00e9es (Jinan Greent Tai Green, granit noir pur)
Une structure min\u00e9rale dense, une teneur en quartz raisonnable, des cristaux fins et uniformes, un faible coefficient de dilatation thermique, de faibles contraintes internes et une r\u00e9sistance \u00e0 la d\u00e9formation : telles sont les caract\u00e9ristiques qui constituent la norme dominante pour les machines \u00e0 mesurer tridimensionnelles (MMT).
Couleurs claires (granit blanc, granit rouge, granit multicolore)
Peuvent pr\u00e9senter une teneur plus \u00e9lev\u00e9e en mica et en min\u00e9raux fragiles, une granulom\u00e9trie h\u00e9t\u00e9rog\u00e8ne, ainsi qu\u2019une stabilit\u00e9 thermique et au vieillissement inf\u00e9rieure \u00e0 celle des mat\u00e9riaux fonc\u00e9s \u00e0 grain fin ; ils sont sujets aux microd\u00e9formations et aux variations de pr\u00e9cision.<\/li>\n\n\n\n

III. Comment choisir le granit pour une machine \u00e0 mesurer tridimensionnelle (MMT) en fonction de la couleur
Priorit\u00e9 : granit fonc\u00e9 pr\u00e9sentant une couleur uniforme, un grain fin, sans motifs apparents ni grandes taches (le \u00ab Jinan Green \u00bb est le premier choix) ;
\u00c0 \u00e9viter : les mat\u00e9riaux pr\u00e9sentant un m\u00e9lange de couleurs trop marqu\u00e9, des veines blanches et des stries noires, d\u2019importantes variations de couleur localis\u00e9es et un grain tr\u00e8s irr\u00e9gulier ; ne vous fiez donc pas uniquement \u00e0 l\u2019aspect esth\u00e9tique. Privil\u00e9giez les mat\u00e9riaux bruts de qualit\u00e9 industrielle, caract\u00e9ris\u00e9s par une couleur uniforme, une texture dense et une cristallisation homog\u00e8ne, plut\u00f4t que les pierres de qualit\u00e9 d\u00e9corative.<\/p>\n\n\n\n
IV. R\u00e9sum\u00e9 Does the color of granite affect the accuracy of a CMM? Conclusion: Color itself does not directly determine accurut the stone material, mineral species, and crystalline structure behind the color significantly affect accuracy. I. Key Points FirstIt is not “black is accurate, white is noor is merely an external manifestation.However, within the same color family,…<\/p>","protected":false},"author":1,"featured_media":2587,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_seopress_titles_title":"","_seopress_titles_desc":"","_seopress_robots_index":"","_seopress_robots_follow":"","_seopress_robots_imageindex":"","_seopress_robots_snippet":"","_seopress_robots_primary_cat":"none","_seopress_robots_breadcrumbs":"","_seopress_robots_freeze_modified_date":"","_seopress_robots_custom_modified_date":"","_seopress_robots_canonical":"","_seopress_social_fb_title":"","_seopress_social_fb_desc":"","_seopress_social_fb_img":"","_seopress_social_fb_img_attachment_id":0,"_seopress_social_fb_img_width":0,"_seopress_social_fb_img_height":0,"_seopress_social_twitter_title":"","_seopress_social_twitter_desc":"","_seopress_social_twitter_img":"","_seopress_social_twitter_img_attachment_id":0,"_seopress_social_twitter_img_width":0,"_seopress_social_twitter_img_height":0,"_seopress_redirections_value":"","_seopress_redirections_enabled":"","_seopress_redirections_enabled_regex":"","_seopress_redirections_logged_status":"both","_seopress_redirections_param":"","_seopress_redirections_type":301,"_seopress_analysis_target_kw":"","_kad_blocks_custom_css":"","_kad_blocks_head_custom_js":"","_kad_blocks_body_custom_js":"","_kad_blocks_footer_custom_js":"","_kadence_starter_templates_imported_post":false,"_kad_post_transparent":"","_kad_post_title":"","_kad_post_layout":"","_kad_post_sidebar_id":"","_kad_post_content_style":"","_kad_post_vertical_padding":"","_kad_post_feature":"","_kad_post_feature_position":"","_kad_post_header":false,"_kad_post_footer":false,"_kad_post_classname":"","footnotes":""},"categories":[35],"tags":[],"class_list":["post-2584","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-news"],"taxonomy_info":{"category":[{"value":35,"label":"NEWS"}]},"featured_image_src_large":["https:\/\/jtlcnc.com\/wp-content\/uploads\/2026\/04\/\u5fae\u4fe1\u56fe\u7247_20260428145938_16_25.png",799,784,false],"author_info":{"display_name":"jinxing6611@gmail.com","author_link":"https:\/\/jtlcnc.com\/fr\/author\/jtlcnc\/"},"comment_info":0,"category_info":[{"term_id":35,"name":"NEWS","slug":"news","term_group":0,"term_taxonomy_id":35,"taxonomy":"category","description":"","parent":0,"count":311,"filter":"raw","cat_ID":35,"category_count":311,"category_description":"","cat_name":"NEWS","category_nicename":"news","category_parent":0}],"tag_info":false,"_links":{"self":[{"href":"https:\/\/jtlcnc.com\/fr\/wp-json\/wp\/v2\/posts\/2584","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/jtlcnc.com\/fr\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/jtlcnc.com\/fr\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/jtlcnc.com\/fr\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/jtlcnc.com\/fr\/wp-json\/wp\/v2\/comments?post=2584"}],"version-history":[{"count":1,"href":"https:\/\/jtlcnc.com\/fr\/wp-json\/wp\/v2\/posts\/2584\/revisions"}],"predecessor-version":[{"id":2588,"href":"https:\/\/jtlcnc.com\/fr\/wp-json\/wp\/v2\/posts\/2584\/revisions\/2588"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/jtlcnc.com\/fr\/wp-json\/wp\/v2\/media\/2587"}],"wp:attachment":[{"href":"https:\/\/jtlcnc.com\/fr\/wp-json\/wp\/v2\/media?parent=2584"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/jtlcnc.com\/fr\/wp-json\/wp\/v2\/categories?post=2584"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/jtlcnc.com\/fr\/wp-json\/wp\/v2\/tags?post=2584"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
La couleur n'a pas d'incidence sur la pr\u00e9cision, mais elle refl\u00e8te la structure min\u00e9rale et la qualit\u00e9 du mat\u00e9riau ; les machines \u00e0 mesurer tridimensionnelles (CMM) doivent \u00eatre \u00e9quip\u00e9es d'un socle en granit industriel fonc\u00e9, de couleur uniforme et \u00e0 grain fin ; plus le motif est irr\u00e9gulier, moins la stabilit\u00e9 de la pr\u00e9cision sera bonne.<\/p>\n\n\n\n![\"\"](\"https:\/\/jtlcnc.com\/wp-content\/uploads\/2026\/04\/3.png\")
