Cutter machining method and cutter

The invention provides a tool machining method and a tool. The tool machining method comprises the first step, the second step and the third step. The step S1 comprises the step of preparing a cutter body, and the cutter body comprises a cutting edge part; in the step S2, a rough hard alloy layer is formed on the blade part by adopting a cold spraying method; the step S3 comprises edging the cutting edge part, and the hard alloy layer forms a micro sawtooth structure on the cutting edge part. The machining difficulty of the tool with the micro-sawtooth structure can be reduced, the production efficiency is improved, and therefore the machining cost of the tool is reduced. 本申请提供了一种刀具加工方法与刀具，刀具加工方法包括步骤S1、步骤S2和步骤S3；所述步骤S1包括制备刀体，所述刀体包括刀刃部；所述步骤S2包括采用冷喷涂的方法在所述刀刃部形成粗糙的硬质合金层；所述步骤S3包括对所述刀刃部开刃，所述硬质合金层在所述刀刃部形成微锯齿结构。本申请可以降低具有微锯齿结构的刀具的加工难度，提高生产效率，从而降低刀具的加工成本。
