通过对 POLMAX 材质试件在不同切削条件下的加工试验，重点分析了涂层刀具的磨损形式，总结出了切削用量影响刀具磨损的规律。研究结果表明：YG 类涂层硬质合金刀具加工淬硬 POLMAX 不锈钢时，低速阶段主要表现为粘结磨损，高速阶段主要表现为氧化磨损与扩散磨损；切削用量中切削速度对刀具磨损影响最大，当切削速度较低时(小于50 m/ min)刀具磨损量几乎保持在同样的水平，而当切削速度达到120 m/ min 以上时，刀具磨损量急剧上升。
通過對 POLMAX 材質試件在不同切削條件下的加工試驗，重點分析瞭塗層刀具的磨損形式，總結齣瞭切削用量影響刀具磨損的規律。研究結果錶明：YG 類塗層硬質閤金刀具加工淬硬 POLMAX 不鏽鋼時，低速階段主要錶現為粘結磨損，高速階段主要錶現為氧化磨損與擴散磨損；切削用量中切削速度對刀具磨損影響最大，噹切削速度較低時(小于50 m/ min)刀具磨損量幾乎保持在同樣的水平，而噹切削速度達到120 m/ min 以上時，刀具磨損量急劇上升。

By testing the parts of POLMAX material in different machining conditions,the wear of coated cutting tools is ana-lyzed emphatically, and the correlativity between tool wear and cutting condition is then summarized. The results show that, when YG coated carbide tool machining hardened POLMAX steel, it is mainly adhesive wear in low speed stage, and is mainly oxidation wear and diffusion wear in high speed stage; the cutting speed has the greatest influence on the tool wear. When the cutting speed is low (less than 50m/ min), the tool wear remains almost at the same level, and when the cutting speed reaches up to 120m/ min, the tool wear is rising sharply.
