The invention relates to a polishing method for a metal diaphragm of a diaphragm compressor. The polishing method comprises the following steps that S1, the metal diaphragm is installed above a polishing base with a lower polishing disc; s2, polishing paste is smeared on the surface of the metal diaphragm or the polished flannelette; an upper polishing disc which is wrapped with polishing flannelette and provided with a cooling water channel is installed above the metal diaphragm; s3, the upper polishing disc and the lower polishing disc are pressed tightly, and the metal diaphragm is polished; the polishing paste is Al2O3 particles and/or SiO2 particles, and the particle size is 0.1-20 [mu] m, preferably 1-10 [mu] m. The surface roughness of the polished metal diaphragm is reduced, the surface residual stress is reduced, the diaphragm is not curled, and the anti-fatigue performance of the diaphragm is improved. 本公开涉及一种隔膜压缩机金属膜片的抛光方法，所述抛光方法包括如下步骤：S1、将所述金属膜片安装于带有下抛光盘的抛光基座上方；S2、将抛光膏涂抹在所述金属膜片表面或所述抛光绒布上；将包裹抛光绒布且带
