Used on universal and CNC lathes, turning tools play a key role in many different operations such as roughing, finishing, grooving, threading and internal machining.<\/p>\n<h2>Structure and Types of Turning Tools<\/h2>\n<p>Turning tools generally consist of two main components: the <strong>toolholder body<\/strong> and the <strong>cutting inserts (carbide inserts or HSS tips)<\/strong> mounted at the tip.<\/p>\n<h2>1. External Turning Tools (External Toolholders)<\/h2>\n<ul>\n<li><strong>Roughing and Finishing Tools:<\/strong> Remove material from the outer surface of the workpiece to achieve the required diameter. They can cut by approaching longitudinally or from the face.<\/li>\n<li><strong>Facing Tools:<\/strong> Remove material from the face perpendicular to the part axis to set the part length and produce a flat face.<\/li>\n<\/ul>\n<h2>2. Internal Turning Tools (Boring Bars)<\/h2>\n<ul>\n<li>Used to machine the internal surfaces of pre-drilled or cored cast parts to achieve an accurate diameter and a smooth internal finish.<\/li>\n<li>Because their long, slender design makes them prone to vibration (chatter), a suitable bar diameter and cutting parameters must be selected.<\/li>\n<\/ul>\n<h2>3. Grooving and Parting Tools<\/h2>\n<ul>\n<li><strong>External and Internal Grooving Tools:<\/strong> Used to cut circlip, O-ring or locking grooves in the part.<\/li>\n<li><strong>Parting Tools:<\/strong> Used with narrow, long-form inserts to separate (part off) the finished part from the bar stock.<\/li>\n<\/ul>\n<h2>4. Threading Tools<\/h2>\n<ul>\n<li>Used with inserts of a special angle to cut threads of specific pitches and profiles (Metric, Whitworth etc.) on the outer diameter of the part or inside a bore.<\/li>\n<\/ul>\n<h2>Cutting Tool Materials<\/h2>\n<ul>\n<li><strong>HSS (High-Speed Steel) Turning Tools:<\/strong> Can be reground and reused repeatedly. Thanks to their high toughness, they are preferred on universal lathes and for interrupted cuts.<\/li>\n<li><strong>Carbide Indexable Insert Toolholders:<\/strong> Offer high cutting speeds and long tool life on CNC lathes and in series production. A worn insert is easily indexed or replaced with a new one.<\/li>\n<\/ul>\n<h2>Correct Use and Technical Recommendations<\/h2>\n<ol>\n<li><strong>Centre Height Setting:<\/strong> The tip of the turning tool must be <strong>exactly level<\/strong> with the lathe spindle axis. Setting it too low or too high impairs the surface finish and causes the insert to break.<\/li>\n<li><strong>Rigidity and Overhang:<\/strong> When clamping the toolholder in the tool post, the overhang should be kept as short as possible. Deflection and vibration both shorten tool life and reduce dimensional accuracy.<\/li>\n<li><strong>Coolant:<\/strong> Coolant should be applied continuously to the cutting zone to reduce heat and aid chip evacuation<\/li>\n<\/ol>\n","protected":false},"excerpt":{"rendered":"<p>An overview of turning toolholders: external, boring, grooving, parting and threading tools, tool materials and best practice for setup.<\/p>\n","protected":false},"author":4,"featured_media":2466,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[76],"tags":[],"class_list":["post-2503","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-blog"],"_links":{"self":[{"href":"https:\/\/temak.com.tr\/en\/wp-json\/wp\/v2\/posts\/2503","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/temak.com.tr\/en\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/temak.com.tr\/en\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/temak.com.tr\/en\/wp-json\/wp\/v2\/users\/4"}],"replies":[{"embeddable":true,"href":"https:\/\/temak.com.tr\/en\/wp-json\/wp\/v2\/comments?post=2503"}],"version-history":[{"count":0,"href":"https:\/\/temak.com.tr\/en\/wp-json\/wp\/v2\/posts\/2503\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/temak.com.tr\/en\/wp-json\/wp\/v2\/media\/2466"}],"wp:attachment":[{"href":"https:\/\/temak.com.tr\/en\/wp-json\/wp\/v2\/media?parent=2503"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/temak.com.tr\/en\/wp-json\/wp\/v2\/categories?post=2503"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/temak.com.tr\/en\/wp-json\/wp\/v2\/tags?post=2503"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
