高强度球墨铸铁是一种新颖的结构材料,日益广泛地应用于苏联各机械制造工厂。然而,有关加工这种铸铁的一些必要的知识,文献中尚付阙如。切削片状石墨铸铁时,一般不使用冷却液。其原因之一是怕细铁屑及铁末堵塞冷却系统及弄髒机床。加工高强度铸铁比加工普通灰铸铁能得到较有利些的切屑(成捲曲及螺旋状)。因此,加工这种新颖铸铁时,对于使用冷却液的适合性的试验,具 High-strength ductile iron is a novel structural material, increasingly widely used in various Soviet machinery manufacturing plants. However, some of the necessary knowledge about the machining of such cast iron is missing from the literature. When cutting flaky graphite cast iron, coolant is not normally used. One of the reasons for this is the fear of blocking the cooling system and fouling machine tools with fine iron filings and iron filings. Processing of high-strength cast iron than ordinary gray cast iron can get more favorable chip (into a curly and spiral). Therefore, the processing of such a new cast iron, the use of coolant test suitability
