This sharpness minimizes cutting resistance, reduces heat generation, and prevents Built-Up Edge (BUE) formation on gummy stainless steels.\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cdiv class=\"faq-q\"\u003eQ: What is the main difference between metric TCMT110208 and imperial TCMT21.52 designations?\u003c\/div\u003e\n\u003cdiv class=\"faq-a\"\u003eA: They refer to the exact same physical size. ISO TCMT110208 uses metric dimensions (11mm length, 2.38mm thickness, 0.8mm radius), while ANSI TCMT21.52 uses 1\/16th-inch fractions (2 = 2\/8\" IC, 1.5 = 1.5\/16\" thickness, 2 = 2\/64\" radius).\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cdiv class=\"faq-q\"\u003eQ: How does the SU chipbreaker prevent stringy chip wrapping?\u003c\/div\u003e\n\u003cdiv class=\"faq-a\"\u003eA: The SU chipbreaker features a variable-angle rake pocket designed specifically to curl ductile material chips into tight coils at both light (0.5 mm) and medium (2.5 mm) depths of cut.\u003c\/div\u003e\n\u003c\/div\u003e\n\u003ch3\u003eTroubleshooting Quick Reference\u003c\/h3\u003e\n\u003cdiv class=\"table-responsive\"\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003eProblem Encountered\u003c\/th\u003e\n\u003cth\u003eProbable Cause\u003c\/th\u003e\n\u003cth\u003eRecommended Solution\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eBuilt-Up Edge (BUE) \/ Material Sticking\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eCutting speed Vc is too low or cutting temperature is insufficient for PVD coating activation\u003c\/td\u003e\n\u003ctd\u003eIncrease cutting speed Vc by 15-20% and ensure high-pressure coolant is directed at the cutting zone.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eNotch Wear at Depth-of-Cut Line\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eWork-hardened surface layer of stainless steel wearing down the insert corner\u003c\/td\u003e\n\u003ctd\u003eVary the depth of cut (ap) across passes or switch to an insert with a larger corner radius.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eVibration \/ Chatter Surface Marks\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eWorkpiece setup flexibility or excessive overhang on internal boring bar\u003c\/td\u003e\n\u003ctd\u003eReduce depth of cut (ap), shorten tool overhang, or select 0.4 mm corner radius (TCMT110204).\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/div\u003e\n\u003c!-- Grade Comparison \u0026 Authority Tip --\u003e\n\u003cdiv class=\"tip-box\"\u003e\n\u003cdiv class=\"tip-title\"\u003eGrade Comparison Tip \u0026amp; Certified Standards Reference\u003c\/div\u003e\n\u003cp\u003eAccording to ISO 513:2012 classification standards, SUMITOMO AC630M falls within the ISO M15–M30 range for stainless steels and ISO S15–S25 range for heat-resistant alloys, providing a balance of toughness and wear resistance.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e","brand":"Sumitomo Electric","offers":[{"title":"Default Title","offer_id":43396363124908,"sku":"TCMT110208N-SU AC630M","price":53.55,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0592\/7328\/1708\/files\/SUMITOMO_TCMT110208N-SU_AC630M_PVD_Coated_Carbide_Turning_Insert.jpg?v=1787902397","url":"https:\/\/cnchome-beyond.com\/products\/sumitomo-tcmt110208n-su-ac630m-carbide-insert","provider":"CNCHome-Beyond","version":"1.0","type":"link"}
