                Titanium\u2019s low thermal conductivity (6.7 W\/m\u00b7K \u2014 roughly 1\/8 of steel) traps cutting heat at the tool tip instead of dissipating it into the workpiece. That concentrated heat, combined with titanium\u2019s HCP crystal structure, causes work hardening when feed rate drops too low or the drill dwells. The fix is counterintuitive: keep speeds conservative (50\u2013230 […]<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[1],"tags":[],"class_list":["post-4225","post","type-post","status-publish","format-standard","hentry","category-blog"],"_links":{"self":[{"href":"https:\/\/hontitan.com\/ko\/wp-json\/wp\/v2\/posts\/4225","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/hontitan.com\/ko\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/hontitan.com\/ko\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/hontitan.com\/ko\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/hontitan.com\/ko\/wp-json\/wp\/v2\/comments?post=4225"}],"version-history":[{"count":1,"href":"https:\/\/hontitan.com\/ko\/wp-json\/wp\/v2\/posts\/4225\/revisions"}],"predecessor-version":[{"id":4233,"href":"https:\/\/hontitan.com\/ko\/wp-json\/wp\/v2\/posts\/4225\/revisions\/4233"}],"wp:attachment":[{"href":"https:\/\/hontitan.com\/ko\/wp-json\/wp\/v2\/media?parent=4225"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/hontitan.com\/ko\/wp-json\/wp\/v2\/categories?post=4225"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/hontitan.com\/ko\/wp-json\/wp\/v2\/tags?post=4225"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
