我厂机动科轧辊工段在C8450轧辊车床上加工轧辊时,对刀具采用了强化喷雾冷却,效果较好。刀具散热好,提高了刀具的耐用度,相应可以提高切削速度和表面加工质量。以粗车轧辊为例,当n=28转/分,t=30毫米,s=0.8毫米/转时,不用喷雾冷却时,加工中刀尖有时崩火星,切屑呈红黄色,加工十分钟后刀杆烫手。 I plant Mazongke roll section C8450 roll lathe processing roller, the tool used to strengthen the spray cooling, the effect is better. Tool cooling is good, improve the durability of the tool, the corresponding can improve the cutting speed and surface processing quality. Take the roughing roll as an example, when n = 28 rpm, t = 30 mm, s = 0.8 mm / rev, when the nozzle is cooled without spraying, the machining tip may sometimes collapse into sparks, the chips are reddish yellow and the machining time is ten minutes Arbor hot.
