Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
Fig. 4 shows, a milling cutter for compartment groove machined part, including handle of a knife 1 and cutter body 2, be equipped with a plurality of cutting edges with cutter body integrated into one piece on the cutter body 2, the cutting edge carries out the spiral along the axial of cutter body 2 and extends, and is adjacent be formed with spiral helicine chip groove between the cutting edge, cutter body 2 divide into cutter body 21 and lower cutter body 22, the cutting edge spiral on last cutter body 21 and the lower cutter body 22 is to opposite. In this embodiment, the rotation direction of the cutting edge of the upper cutter body 21 is right-handed, and the rotation direction of the cutting edge of the lower cutter body 22 is left-handed. In other embodiments, the cutting edge of the upper cutter body 21 may rotate in a left direction, and the cutting edge of the lower cutter body 22 may rotate in a right direction.
Specifically, the upper blade body 21 and the lower blade body 22 are equal in length. Of course, in other embodiments, the lengths of the upper blade body 21 and the lower blade body 22 may not be equal.
