由于高硅铝合金中含有大量硅结晶粒子，硬度较大的硅结晶粒子在切削中会加速刀具的磨损，所以，其被切削性非常不好。为解决这一问题，以往是使用大量切削油进行切削加工。但是，随着环境意识的提高，大量切削油的使用所造成的环境污染的问题不得不被认识并进行改变。使用对切削点进行微量植物性润滑油润滑和冷风冷却的方法进行研究，探讨对高硅铝合金切削面的影响。并因此探讨半干式切削加工的可行性。
As high-silicon aluminum alloy contains a large number of silicon crystal particles, the hardness of the larger silicon particles in the cutting will accelerate the tool wear, so its machinability is very poor. To solve this problem, the past is the use of a large number of cutting oil cutting. However, with the improvement of environmental awareness, the problem of environmental pollution caused by the use of large amounts of cutting oil has to be recognized and changed. The method of micro-plant lubricant lubrication and cold air cooling on the cutting point was used to study the influence on the cutting surface of high-silicon aluminum alloy. And therefore explore the feasibility of semi-dry cutting.
