This preserves ultra-sharp cutting edges necessary to prevent work hardening and built-up edge (BUE) in tough austenitic stainless steels (304\/316) and titanium alloys.\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"margin-bottom: 12px;\"\u003e\n\u003cdiv style=\"font-weight: bold; color: #1e293b; font-size: 14px; margin-bottom: 4px;\"\u003eQ2: What causes chip wrapping on the workpiece, and how can I fix it with the TNMG160404N-GU?\u003c\/div\u003e\n\u003cdiv style=\"color: #475569; font-size: 13px;\"\u003eA: Stringy continuous chips occur when cutting below the minimum feed rate or depth of cut required by the GU chipbreaker. To eliminate chip wrapping: increase feed rate above 0.18 mm\/rev (0.007 ipr) or increase depth of cut above 1.0 mm (0.040 in) to fully engage the 3D chip-breaking ridge.\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cdiv style=\"font-weight: bold; color: #1e293b; font-size: 14px; margin-bottom: 4px;\"\u003eQ3: How do I handle thermal cracking or premature insert chipping during interrupted cutting?\u003c\/div\u003e\n\u003cdiv style=\"color: #475569; font-size: 13px;\"\u003eA: Check coolant delivery. Ensure high-pressure coolant is directed precisely at the cutting zone to avoid thermal cycling, or switch to dry cutting under controlled speed if thermal shock is severe. Alternatively, verify that tool shank rigidity matches MTJNR clamping standards.\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c!-- 8.
