叶片的加工表面完整性在电力设备制造业中至关重要。近年来，许多刀片事故都是由于在实际加工难切削材料时使用了不当的切削液造成的，但切削液对表面完整性和使用性能的影响却一直被忽视。结合两种通用切削液的性能，研究了切削液对典型刀片材料表面质量的影响。对加工表面的元素组成、表面形貌、残余应力和硬度进行了分析。结果表明，在精密加工中，切削液不能降低切削力。加入Cl后，在加工过程中会出现局部和不规则的元素Cr损失，损失深度为1-2 μm。CF-206下的加工表面光滑，CF-210下的粗糙度最高。干切削的残余拉应力最高，而CF-210的残余拉应力最低。切削液下的表面加工硬化更高，深度为20-30 µm。这些结果对于控制叶片的精密加工表面和亚表面，使其具有高的完整性和使用性能具有重要意义。
The machined surface integrity of blades is of utmost importance in the power equipment manufacturing industry. Recently, many blade accidents have been attributable to the misuse of cutting fluids that were necessary in the actual machining of difficult-to-cut materials, but the effect of the cutting fluid on surface integrity and service performance has been persistently neglected. In this article, an investigation into the effect of cutting fluids on the surface quality of a typical blade material was undertaken, combined with properties of two universal cutting fluids. Element composition, surface morphology, residual stress and hardness of the machined surfaces were investigated. The results indicated that cutting fluids could not reduce cutting forces in precision machining. There were some places where local and irregular elemental Cr loss was incurred when machined with the additive Cl, and the depth of Cr loss was 1–2 µm. The machined surface under CF-206 was smooth, and the roughness of CF-210 was the highest. The tensile residual stresses of dry cutting were the highest, whereas those of CF-210 were the lowest. Surface work hardening under cutting fluids was higher, with depths of 20–30 µm. These results are significant for the control of precision machined surfaces and subsurfaces of blades with high integrity and service performance.
