Application Background \u25a0 The main challenge in mass production of high-precision hardened steel parts is to maintain superior geometric accuracy, surface finish, dimensional consistency and stability under post-quenching hard conditions. It involves not only material, process and efficiency issues, but also a comprehensive test of cutting tool performance, machine rigidity and thermal control. \u25a0 Taking the finishing turning of inner raceway on bearing seat ring as an example below, Worldia custom tools effectively extend tool life and reduce tool change downtime, delivering an efficient, stable and durable machining solution for customers. Solution Analysis \u25ce In this case of finishing turning the inner raceway of bearing seat ring, the customer required […]<\/p>\n","protected":false},"author":5,"featured_media":20748,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[228],"tags":[],"class_list":["post-20747","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-application-news"],"_links":{"self":[{"href":"https:\/\/www.worldia-tools.com\/ja\/wp-json\/wp\/v2\/posts\/20747","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.worldia-tools.com\/ja\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.worldia-tools.com\/ja\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.worldia-tools.com\/ja\/wp-json\/wp\/v2\/users\/5"}],"replies":[{"embeddable":true,"href":"https:\/\/www.worldia-tools.com\/ja\/wp-json\/wp\/v2\/comments?post=20747"}],"version-history":[{"count":1,"href":"https:\/\/www.worldia-tools.com\/ja\/wp-json\/wp\/v2\/posts\/20747\/revisions"}],"predecessor-version":[{"id":20752,"href":"https:\/\/www.worldia-tools.com\/ja\/wp-json\/wp\/v2\/posts\/20747\/revisions\/20752"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.worldia-tools.com\/ja\/wp-json\/wp\/v2\/media\/20748"}],"wp:attachment":[{"href":"https:\/\/www.worldia-tools.com\/ja\/wp-json\/wp\/v2\/media?parent=20747"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.worldia-tools.com\/ja\/wp-json\/wp\/v2\/categories?post=20747"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.worldia-tools.com\/ja\/wp-json\/wp\/v2\/tags?post=20747"}],"curies":[{"name":"WP","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
