by the Rapidcision Engineering Team | Last updated: June 2026 Surface roughness is the microscopic texture of peaks and valleys left on a part after machining, and Ra is the number used to specify it on most drawings. The practical anchor points are simple: Ra 3.2 \u00b5m is the standard, economical finish straight off a CNC mill or lathe, and Ra 1.6 \u00b5m is the usual threshold for precision mating surfaces. Anything smoother than that climbs in cost quickly, because it takes finer tooling, slower feeds, or a secondary process like grinding. The conversion chart below lets you move between Ra, Rz, RMS, and the older N-grade system, and [&hellip;]<\/p>\n","protected":false},"author":2,"featured_media":6960,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[15,11],"tags":[],"class_list":["post-6958","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-blog","category-cnc-machining"],"_links":{"self":[{"href":"https:\/\/rapidcision.com\/ja\/wp-json\/wp\/v2\/posts\/6958","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/rapidcision.com\/ja\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/rapidcision.com\/ja\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/rapidcision.com\/ja\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/rapidcision.com\/ja\/wp-json\/wp\/v2\/comments?post=6958"}],"version-history":[{"count":2,"href":"https:\/\/rapidcision.com\/ja\/wp-json\/wp\/v2\/posts\/6958\/revisions"}],"predecessor-version":[{"id":7289,"href":"https:\/\/rapidcision.com\/ja\/wp-json\/wp\/v2\/posts\/6958\/revisions\/7289"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/rapidcision.com\/ja\/wp-json\/wp\/v2\/media\/6960"}],"wp:attachment":[{"href":"https:\/\/rapidcision.com\/ja\/wp-json\/wp\/v2\/media?parent=6958"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/rapidcision.com\/ja\/wp-json\/wp\/v2\/categories?post=6958"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/rapidcision.com\/ja\/wp-json\/wp\/v2\/tags?post=6958"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
