High-entropy alloys (HEAs) have attracted wide attention due to its excellent mechanical properties, and have become a new alloy material with high application potential. However, although the research on the machining performance of HEAs has become a research hot spot, the grinding performance of HEAs has received little attention. The grinding chip morphology and the grinding surface quality of FeCoNiCrMo0.1 and FeCoNiCrAl0.1 HEAs were investigated in this article. The grinding chips are closely related to grinding surface quality, and the observation and analysis of the grinding chips are helpful to improve surface quality. Orthogonal experiments were conducted by electroplated, resin-bonded and ceramic-bonded grinding wheels in order to obtain high grinding surface quality based on surface roughness Ra and surface morphology, the effects of grinding parameters and wheels on the grinding force, surface roughness Ra and surface morphology were analyzed. This paper is helpful to understand the grinding performance of these two HEAs, determine the optimal grinding process parameters suitable for HEAs, and provide engineering guidance for obtaining high surface quality HEA parts.
