为了探讨国内外高端产品的质量水平,为国产硬质合金铣刀性能提升提供有益的指导,对比研究了国内外知名品牌铣刀的耐磨性和失效形式。采用端面中心对称干切削方式,按照实验室铣刀试验规范对相同材质的国产某品牌刀片和国外刀片在相同工艺条件下进行了铣削对比实验,工件材料为45#钢。实验结果表明:两种刀片高速干式铣削45#钢的寿命没有明显差异。国产刀片失效形式主要为磨损失效,其在45#钢的高速干式铣削上显示出了较高的耐磨性;国外刀片同时表现出崩刃失效。
In order to explore the quality level of high-end products at home and abroad, to provide useful guidance for the performance improvement of domestic carbide milling cutter, comparative study of wear resistance and failure modes of well-known brand milling cutter at home and abroad. Using end center symmetrical dry cutting mode, according to the laboratory milling cutter test specification for the same material made of a certain brand of foreign brands and blades in the same process conditions milling comparison experiment, the workpiece material is 45 # steel. The experimental results show that there is no significant difference in the service life of 45 # steel between the two kinds of high-speed dry milling blades. The failure form of the domestic blade is mainly wear failure, which shows high wear resistance in 45 # steel high-speed dry milling; the foreign blades also show collapse failure.
