The invention relates to a milling method of a graphene aluminum-based composite material. A PCD milling cutter is adopted for processing, has the rotation speed of 10,000-18,000r/min, has the feed amount of 0.05-0.15mm/r, and has the cutting depth of 0.1-0.3mm; the radial run-out, the end surface run-out and the axial float of a machine tool spindle are less than 0.02mm. By the method, the low-cost, efficient and high-precision milling of the graphene aluminum-based composite material is realized by selecting the PCD milling cutter and reasonable processing technological parameters, so that the dimensional tolerance of the graphene aluminum-based composite material can reach 5 microns, the surface roughness can reach Ra0.8, and the yield of the graphene aluminum-based composite material can be enhanced to 95%.
