[0012] figure 1 It is a schematic diagram of the structure of the present invention. The picture includes blank → quenching and tempering → sampling → drilling center hole → turning one → turning two → turning and milling one → fitter deburring → drilling Φ70 oil hole → cam profile quenching → turning and milling two → fine grinding cam → flaw detection and demagnetization → acid Erosion inspection→clamp 1→vibration deburring→clamp 2→three-coordinate inspection→cam contour inspection→clamp 3→finished product inspection→cleaning→install positioning sleeve→oiling→warehousing. First, the cam profile of the blank is quenched and tempered, and then sampled. The center hole is drilled through Turn 1 and Turn 2. The flange end bolt mounting holes on the camshaft are processed by turning and milling, and processed by a turning and milling machining center. The measuring process determines the positioning pin holes and bolt mounting holes for the phase angle of each camshaft at the two...
