在金属切削过程中,因被加工的金属发生变形,刀具与切屑、刀具与工件间不断摩擦而产生切削力和切削温度,严重地影响了切削效率、加工质量以及刀具的使用寿命。因此,如何减小切削力和降低切削温度,是切削加工中的一个重要问题。实践证明,合理选用切削液,可以提高加工效率、降低已加工表面粗糙度、延长刀具寿命等。 按切削液的性质划分,切削液可分为纯油性和水溶性两大类。水溶性切削液根据成分的不同,又可分为乳化液、半合成液(微乳化液)、合成液三
In the metal cutting process, due to deformation of the metal being processed, cutting tool and chip, tool and workpiece friction and cutting force and cutting temperature, seriously affecting the cutting efficiency, processing quality and tool life. Therefore, how to reduce the cutting force and reduce the cutting temperature is an important issue in the cutting process. Practice has proved that a reasonable choice of cutting fluid, can improve the processing efficiency, reduce the surface roughness has been machined, to extend tool life. According to the nature of the cutting fluid, cutting fluid can be divided into pure oil and water-soluble two categories. Water-soluble cutting fluid according to the composition of different, can be divided into emulsion, semi-synthetic liquid (micro-emulsion), synthetic liquid three
