分别使用硬质合金刀具、金刚石刀具、立方氮化硼刀具对氟金云母陶瓷及二硅酸锂玻璃陶瓷材料进行车削试验。利用显微镜观察刀具磨损形貌,通过能谱分析研究了刀具的磨损机理。试验结果表明,刀具磨损部位主要集中在刀尖和后刀面,刀具磨损形式主要为磨料磨损和粘结磨损。用硬质合金刀具车削氟金云母陶瓷时,切削深度越小,磨料磨损越严重。 Carbide tools, diamond tools, and cubic boron nitride tools were respectively used for turning tests on fluorophlogopite mica and lithium disilicate glass ceramic materials. The wear morphology of the tool was observed with a microscope, and the wear mechanism of the tool was studied by energy spectrum analysis. The test results show that the tool wear parts mainly focus on the tool tip and the flank face, and the tool wear forms are abrasive wear and bond wear. Carbide cutting tool with fluorocarbon micaceous ceramics, the cutting depth is smaller, abrasive wear more serious.
