The invention discloses a processing technique of end teeth, comprising the steps of 1, preparing a material; 2, forging; 3, carrying out thermal treatment; 4, carrying out turning I; 5, roughly machining teeth; 6, drilling, and machining screw holes; 7, carrying out high-frequency thermal treatment; 8, carrying out carburization thermal treatment; 9, carrying out turning II; 10, grinding; 11, flattening by dressing, and polishing; 12, inspecting, and measuring; 13, cleaning; 14, oiling, and packaging. Modifications are made herein in order to solve the problems that, for instance, end teeth processed by means of existing end tooth processing techniques are low in hardness, poor in wear resistance, prone to rusting, low in surface flatness, prone to causing noise during operating and shortin service life. The processing technique herein has the advantages that, for instance, end tooth hardness is improved, end tooth wear resistance is improved, corrosion resistance of end teeth is improved, surface flatness of end teeth is improved, the end teeth produce less noise during operating, and the end teeth have longer lives.
