Embodiment 1
[0041] like figure 1 Shown is a high-efficiency cutting insert described in this embodiment, including an insert body 100 surrounded by an upper bottom surface 1, a lower bottom surface 2, and a side surface 3 connecting the upper bottom surface 1 and the lower bottom surface 2, the insert The cutting unit 4 is distributed on the main body 100, and the cutting unit 4 includes at least one main cutting edge 5. Under the cutting condition of a certain feed amount, the blade main body 100 and the part move relative to the main cutting edge 5 to promote the blade main body. 100 cuts into the interior of the part, forms curled chips on the rake face, and removes excess material; the main cutting edge 5 is composed of a wiper edge 501, a first cutting edge 502 and a second cutting edge 503. The wiper edge 501 is in a straight state, the wiper edge 501, the first cutting edge 502 and the second cutting edge 503 protrude toward the outer direction of the insert body 100 and form a spa...
Embodiment 2
[0061] like Figure 12 As shown, this embodiment differs from Embodiment 1 in the way of assembling the blade body 100 . Specifically, the blade body 100 can be rotated counterclockwise around the rotation center 28 for cutting processing, which widens the blade body 100 The use range of the blade body 100 enables all parts of the blade body 100 to function. The blade main body 100 is also installed on the blade body with a negative axial angle for cutting, and the cutting clearance angle is reserved. For the polishing effect of the surface of the part, the second secondary cutting edge undertakes the main work of removing the material of the part. At the same time, the secondary cutting edge and its secondary emptying edge will also participate in the actual cutting task in the case of a large depth of cut. At the same time, the secondary cutting edge 6 The first secondary cutting edge, the second secondary cutting edge and their bridging curves are all convex and curved tow...
