在金属切削加工中,钻削工作量约占全部切削加工的35%。由于钻头是最重要的孔加工刀具,钻头磨损后直接影响生产效率、钻孔精度、表而粗糙度和加工成本,故钻头的磨损是孔加工中的一个重要问题。一、钻头磨损形式在钻削过程中,钻头一方面切下切屑,另一方面钻头本身材料中的微波被切 In metal cutting, the drilling workload accounts for about 35% of the total machining. Because the drill bit is the most important hole machining tool, the drill bit wear directly affects the production efficiency, drilling accuracy, surface roughness and processing costs, so the drill bit wear is an important issue in hole machining. First, the form of drill wear In the drilling process, the drill cut the chip on the one hand, on the other hand the drill itself is cut in the microwave material
