Processing method of thin, high and straight cylindrical electrode

The invention discloses a processing method of a thin, high and straight cylindrical electrode. The processing method comprises the following steps: clamping; rough machining: machining a rough geometric component, a reference seat and a blank seat on the electrode blank; finish machining is conducted, specifically, finish machining is conducted on the roughing geometric component in a spiral cutting mode, and thin, high and straight cylindrical electrode teeth are formed on the roughing geometric component; cutter treatment used in finish machining comprises the steps that a straight cylindrical cutter is selected, and a cutter edge of the cutter is ground so that the cutter edge can be provided with an annular receding section and an annular cutting edge section. According to the machining method, the thin, high and straight cylindrical electrode with the ratio of the height to the diameter reaching 5-15 times is machined and formed, the machining requirement is met, the machining method breaks through the
