This ensures higher setup repeatability and lower cutting forces on precision lathe applications.\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cdiv class=\"faq-q\"\u003eQ: How does the FY chipbreaker handle light depths of cut on superalloys?\u003c\/div\u003e\n\u003cdiv class=\"faq-a\"\u003eA: The FY chipbreaker is designed with an aggressive positive rake and a specialized curl ridge, allowing it to efficiently curl and shear thin chips even at cut depths as low as ap = 0.05 mm without rubbing or work-hardening the workpiece.\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\u003eNotch Wear at Depth of Cut Line\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eWork-hardening layer on stainless\/superalloys wearing down the cutting line\u003c\/td\u003e\n\u003ctd\u003eVary the depth of cut ap slightly across finishing passes or increase cutting speed Vc.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eFine Surface Chatter Marks\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eRadial push force causes slender part deflection\u003c\/td\u003e\n\u003ctd\u003eVerify tool overhang is minimized and ensure feed rate f matches the 0.2 mm corner radius recommendations.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eBuilt-Up Edge (BUE) Formation\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eCutting speed Vc is too low for ductile material shearing\u003c\/td\u003e\n\u003ctd\u003eIncrease cutting speed Vc into the recommended high-speed range for AC520U and apply high-pressure coolant.\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 AC520U super PVD coated carbide grade provides exceptional wear resistance and thermal stability at elevated cutting temperatures up to 1000°C, making it superior for high-speed finishing on exotic alloys and stainless steels (ISO M05–M25 \/ S05–S20 range).\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e","brand":"Sumitomo","offers":[{"title":"Default Title","offer_id":43396385865900,"sku":"TNGG160402R-FY AC520U","price":128.62,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0592\/7328\/1708\/files\/SUMITOMO_TNGG160402R-FY_AC520U_PVD_Coated_Carbide_Turning_Insert.jpg?v=1787469732","url":"https:\/\/cnchome-beyond.com\/products\/sumitomo-tngg160402r-fy-ac520u","provider":"CNCHome-Beyond","version":"1.0","type":"link"}
