Summary:An integral multi-edge contour knife processing method comprises the following steps: a knife handle blank is grinded into a benchmark knife handle with the preset precision in a basic shaft system; aPCD knife head blank and the benchmark knife handle are clamped in a centering and aligning manner, and then vacuum welding is performed; and the PCD knife head blank is grinded to reach the preset precision with the benchmark knife handle as a benchmark; and a plurality of cutting edges distributed in a ring-shaped manner and a plurality of chip removing grooves positioned among the cutting edges are formed one by one through laser cutting at the end, far away from the benchmark knife handle, of the PCD knife head blank, and then an integral multi-edge contour knife is obtained, wherein theedge width of each cutting edge is 0.04-0.2 millimeters, the edge surface roughness Ra of each cutting edge is 0.1-0.4 micrometers, and the depth of each chip removing groove is 0.1-0.2 millimeters. The integral multi-edge con
