Machining method of metal ceramic end mill

The invention relates to a machining method of a metal ceramic end mill. The machining method comprises the following process steps that S1, surface treatment is conducted, specifically, the surface of a raw material is cleaned; s2, fine grinding: performing fine grinding on the raw materials into required diameters; s3, forming a spiral groove: forming the spiral groove in the side wall of the finely ground raw material; s4, outer circle accurate grinding is conducted, specifically, the spiral groove is subjected to accurate grinding; and S5, end tooth grinding is conducted, specifically, end face tooth grinding is conducted on the raw materials subjected to outer circle accurate grinding. The method has the effect of reducing the influence of impurities on the surface of the raw material on fine grinding of the raw material. 本申请涉及一种金属陶瓷立铣刀的加工方法，其包括以下工艺步骤：S1、表面处理：对原料表面进行清理；S2、精磨：对原料进行精磨成需要的直径；S3、开螺旋槽：对精磨完成的原料侧壁开螺旋槽；S4、外圆精磨：对螺旋槽进行精磨；S5、磨端齿：对外圆精磨完成的原料进行端面磨齿。本申请具有减少原料表面的杂质对原料精磨的影响的效果。
