在金属切削加工时,刀具切削金属使被加工金属发生变形,同时刀具工件之间不断磨擦,产生切削力及切削温度,它严重地影响了刀具的寿命、切削效率及加工的质量。因此,如何减少切削力和降低切削温度是切削加工中的一个重要问题。减少切削力和温度,固然可以从改善刀具几何形状,材料着手。但是常用的一种方法是选用合适的金属切削液。实践证明:合理选用金属切削液,一般可以提高加工光洁
In metal cutting, the cutting metal metal to be processed metal deformation, while constantly friction between the workpiece tool, resulting in cutting force and cutting temperature, it has seriously affected the life of the cutting tool, cutting efficiency and processing quality. Therefore, how to reduce the cutting force and reduce the cutting temperature is an important issue in the cutting process. Reduce the cutting force and temperature, although it can improve the geometry of the tool, the material to start. However, a commonly used method is to use a suitable metal cutting fluid. Practice has proved that: Rational use of metal cutting fluid, generally can improve the processing smooth
