85W-15Mo钨钼合金是一种耐高温、耐烧蚀的粉末冶金材料,具有能抗热冲击和高速燃气冲刷的优良性能,可用于固体战术导弹发动机舵体,使烧蚀率保持在最低程度,以满足控制系统的需要。但是在机械切削加工极易产生碎裂、崩口和条块状剥落等缺陷,产生大量的废品。为克服切削加工的困难,选择合理的工艺文案而进行了试验,并且从刀具材料和刀具结构以及切削参数上进行了探讨。 85W-15Mo Tungsten-Molybdenum alloy is a high temperature, ablation resistant powder metallurgy material with excellent resistance to thermal shock and high speed gas scrubbing and can be used on solid tactical missile engine rudder to keep ablation rate to a minimum To meet the needs of the control system. However, machining defects such as chipping, chipping, and spalling can easily occur in mechanical cutting, resulting in a large amount of waste products. In order to overcome the difficulty of cutting, select the reasonable craft copy and carry on the test, and the tool material and the structure of the cutter and the cutting parameters are discussed.
