TNMG 刀粒 — 双面 三角形外形，负倾角，转销样式、断屑槽设计 适用于正常的表面抛光需求，以及一般工程不锈钢的轻度至中度旋转 旋转插件 ISO 参考细分 较高编号 = 较坚硬/抗冲击性 较低编号 = 较硬/耐磨 TU5525 the New Universal Turning Grade TU5525 is a truly universal tuning grade suitable for cutting Steel, Stainless Steel, Cast Iron and heat resistant Aaloys. There is no need to hold stock of a multitude of grades reducing the cost of inventory and time wasted changing inserts. One insert for almost all applications. If insert breakage or chipping of the cutting edge is a problem TP2135 may be the answer. Some application do not offer the cutting edge a constant cutting surface whether from a non round part or holes in the part this constant impact on the cutting edge can lead to insert failing. TP2135 is designed to take higher impact loads giving a more secure cutting edge, suitable for cutting steel, stainless steel and heat resistant alloys. TP2135 a Tough Impact Resistant Grade
