我厂用20CrMnTi为原料,高速钢作刀具,加工丝杠。原来每班用4把刀加工12件,光洁度▽4,不符合工艺要求,后用废机油96%、硫化蓖麻油1%、乙醇1%、硬脂酸1%配制成复合切削油,把间歇刷油改为连续打油。实践证明,自配复合切削油,大大优于5号油,加工后工件性能良好,光洁度高于▽5,吃刀量由原来0.125毫米提高到0.15毫米(4把刀), I plant with 20CrMnTi for raw materials, high-speed steel for the tool, screw processing. The original class with four knives processing 12, finish ▽ 4, does not meet the technical requirements, after the waste oil 96%, 1% sulfurized castor oil, ethanol 1%, 1% stearic acid formulated as a composite cutting oil, the intermittent Brush oil instead of continuous oiling. Practice has proved that self-compound cutting oil, much better than the 5th oil, the workpiece after processing performance is good, the finish is higher than ▽ 5, the amount of knife to eat from 0.125 mm to 0.15 mm (4 knives)
