切削液_切削油的选择

      切削液的挑选既要考虑到其本身的润滑性也要考虑其冷却功能,关于精加工易挑选乳化型减摩切削液或低粘度的切削油,关于半精加工和粗加工可挑选低浓度的乳化型减摩切削液或半合成减摩切削液等具有良好冷却功能的切削液在车削铝合金用切削液的挑选方面除了要考虑切削液的润滑性、冷却性等功能外,还要考虑切削液的防锈性、本钱和易保护等方面的功能。切削油易选用粘度相对较低的基础油加入减磨添加剂,这样既可达到润滑减摩,也可有很好冷却和易过虑性。可是切削油存在的问题是闪点低,在高速切削时烟雾较重,闪点低,危险系数较高,并且蒸发快,用户使用本钱相应变高,因此在条件答应的情况下尽量选用铝合金切削液。

       The choice of cutting fluid should not only consider its own lubricity but also its cooling function. For finishing, it is easy to choose emulsified antifriction cutting fluid or cutting oil with low viscosity. For semi finishing and rough machining, it is possible to choose emulsified antifriction cutting fluid with low concentration or semi synthetic antifriction cutting fluid with good cooling function, in addition to the selection of cutting fluid for turning aluminum alloy Besides the functions of lubrication and cooling of cutting fluid, the functions of antirust, cost and easy protection of cutting fluid should also be considered. Cutting oil is easy to choose base oil with relatively low viscosity to add antifriction additives, which can not only achieve lubrication and antifriction, but also have good cooling and easy to filter. However, the problems of cutting oil are low flash point, heavy smoke, low flash point, high risk coefficient, fast evaporation, and correspondingly higher user cost. Therefore, aluminum alloy cutting fluid should be selected as far as possible when conditions permit.

      关于水性切削液,更重要的是要考虑其防锈性。现在常用的水性铝防锈剂有硅酸盐和磷酸脂,关于工序间存放时间较长的工件,在加工时易选用具有磷酸脂型防锈剂的切削液,因为硅类物质与铝材长时间触摸会发作腐蚀产生黑色的“硅斑”。切削液的pH值多保持在8-10之间,如果防锈性不好,铝材在这种碱性条件下很容易被腐蚀。因此铝合金切削液必定要有良好的铝防锈有功能。

      As for water-based cutting fluid, it is more important to consider its rust resistance. At present, the commonly used water-based aluminum antirust agents are silicate and phosphoric acid grease. For workpieces stored for a long time between processes, it is easy to select cutting fluid with phosphoric acid grease type antirust agent during processing, because the long-term touch of silicon and aluminum materials will produce black "Silicon spots" due to corrosion. The pH value of the cutting fluid is mostly kept between 8-10. If the rust resistance is not good, the aluminum is easy to be corroded in this alkaline condition. Therefore, aluminum alloy cutting fluid must have good aluminum rust prevention and function.
