starting the vibrator, the groove milling motor and the feeding motor, wherein the feeding motor can drive the material clamping disc to rotate, and when the material passes through the feeding channel, the material enters the material clamping groove;
when the first correcting plate and the second correcting plate move relatively along the sliding rail, the first correcting inclined plane and the second correcting inclined plane are attached to the side surface of the hexagonal bolt head of the material and enable the material to be stressed and corrected to a proper machining direction;
step four, the materials at the corrected positions continue to move along with the material clamping disc, and the groove milling motor can drive the upper milling cutter and the lower milling cutter to rotate simultaneously when being started, so that the groove milling operation is carried out on the materials moving to the corresponding positions;
and step five, the product after the groove milling operation is finished continuously moves along with the material clamping disc, when the product moves to the position corresponding to the material hooking block, the product leaves the working area of the positioning disc at the moment, the product can be supported on the material hooking block so as to be stressed and separated from the material clamping groove, and then the product can fall onto the discharging guide rail and enters the material receiving hopper after moving along the discharging guide rail.
