摘要:针对难加工材料300M钢的加工性能差、刀具磨损严重等问题,进行了干式与低温微量润滑两种加工条件下的高速铣削300M钢刀具磨损试验。采用超景深显微镜观察了刀具的磨损形貌,通过电子扫描显微镜(SEM)分析了刀具的磨损机理。结果表明:PVD涂层保护刀具的效果好于无涂层刀具和CVD涂层刀具;冷风温度为-45℃、空气压力为0.7MPa、油量为40mL/h时,低温微量润滑技术的作用效果最佳;兼顾加工质量与加工效率时,铣削速度定为400m/min为宜;相比于干式切削,低温微量润滑技术能够有效降低刀片磨粒磨损、刀片表面的粘结磨损、后刀面边界处的氧化磨损,以及轻度的扩散磨损。



Abstract:
 Abstract:For the problem of poor processing performance and severe tool wear of hardtomanufactured material 300M steel, highspeed milling 300M steel tool wear test of dry and CMQL was carried out. The wear morphology of the tool was observed with an ultradeepdepth microscope, and the wear mechanism of the tool was analyzed with a scanning electron microscope (SEM). The results show that PVD coatings protect the tool better than uncoated and CVD coated tools; When the cold air temperature is -45℃, the air pressure is 0.7MPa, and the oil volume is 40mL/h, the effect of CMQL technology is the best; When considering the processing quality and processing efficiency, the milling speed is set to 400m/min; Compared to dry cutting, CMQL technology can effectively reduce abrasive wear of the blade, bond wear on the blade surface, oxidative wear at the flank boundary, and mild diffusion wear.
