    • PROBLEM TO BE SOLVED: To provide a coating insert provided with a reinforced surface area in the only one part of a base material, in regard to a coating cemented carbide cutting tool insert to be used for rough finishing, intermediate finishing and final finishing of a material such as steel and cast iron, especially becoming short chips thereof. SOLUTION: The coating cutting tool insert for metal-machining a material, especially becoming short chip machining comprises a tungsten carbide base material having a binder phase enriched surface area, and a cutting blade is formed by crossing at least one rake face and at lest one clearance surface. The binder phase enriched surface area is at least partially missed in the rake face comprising at least one part of a surface extended from the cutting blade. As a result, optimal combination of cutting blade strength and abrasion resistance is achieved. COPYRIGHT: (C)2006,JPO&NCIPI
    • 要解决的问题:为了提供在基材的仅一个部分中提供加强表面积的涂层刀片,涉及用于粗加工,中间精加工和最终加工的涂层硬质合金刀具刀片 钢和铸铁等材料的精加工,特别是成为短切屑。 解决方案:用于对材料进行金属加工的涂层切削工具刀片,特别是短切削加工包括具有粘结相富集表面积的碳化钨基体材料,并且切割刀片通过将至少一个前刀面和 至少有一个间隙表面。 粘结剂相富集的表面积在前刀面中至少部分地缺失,包括从切割刀片延伸的表面的至少一部分。 结果,实现了切割刀强度和耐磨性的最佳组合。 版权所有(C)2006,JPO&NCIPI
