硼系合金自口抗磨铸铁作为一种新型的抗磨材料已被广泛地应用于发电、矿山等设备中,并已显示了它在其它行业广泛应用的前景。硼系白口耐磨铸铁的性能与高铬铸铁相近,由于我国硼资源丰富,所以成本低,这种白口耐磨铸铁至是符合我国国情的一种新型材料。随着它的进一步被广泛应用,对于述科耐磨铸铁在切削加工中存在的一些主要问题,如可切削加工性刀具材料及切削用量的选择等,受到金切界的关注。本文通过现场试验,优选和确定了刀具的合理几何参 Boron alloy self-mouth anti-wear cast iron as a new type of anti-wear material has been widely used in power generation, mining and other equipment, and has shown its widely used in other industries prospects. Boron white cast iron wear-resistant cast iron performance similar to the high-chromium cast iron, because of our abundant boron resources, so the cost is low, this white cast iron wear-resistant to meet our national conditions is a new type of material. As it is further widely used, there are some main problems in the machining process of machinable wear-resistant cast iron, such as machinability tool material and the choice of cutting dosage, which have drawn much attention from the gold cutters. In this paper, through the field test, optimize and determine the reasonable geometric parameters of the tool
