[0004] The above-mentioned purpose of the present invention is achieved through the following technical solution: a chip-breaking PCD blade for processing aluminum alloy, comprising a cutter body, a chip breaker provided at one end of the cutter body, the chip breaker having a cutting edge, and a chip-breaking protrusion provided on the chip breaker body inside the cutting edge.

[0005] Furthermore, the chip breaking protrusion is gourd-shaped.

[0006] Furthermore, a locking positioning hole is provided on the knife body.

[0007] Furthermore, the blade body has a diamond-shaped structure and is made of cemented carbide.

[0008] Furthermore, the diamond inner angle of the front end of the blade body is 35°.

[0009] Furthermore, the chip breaker is made of PCD.

[0010] Furthermore, a bevel cut is provided at the cutting edge.

[0011] Furthermore, the cutter body and the chip breaker are connected and fixed by welding.

[0012] The advantage of the utility model over the prior art is that during the processing, the cut aluminum chips collide with the chip breaking protrusions of the utility model, thereby achieving the chip breaking effect and effectively solving the chip breaking problem in aluminum alloy processing.

[0016] The present invention will be further described below in conjunction with the accompanying drawings.

[0017] like Figure 1 、 Figure 2 and Figure 3 As shown, a chip-breaking PCD blade for processing aluminum alloys includes a blade body 1, which is provided with a locking positioning hole 2. The blade body 1 has a diamond structure, and the diamond internal angle at the front end of the blade body 1 is 35 degrees. The material is cemented carbide. A chip breaker 3 is welded to one end of the blade body 1. The chip breaker 3 is made of diamond (PCD) material. The chip breaker 3 is provided with a cutting edge 4, and the cutting edge 4 is provided with a bevel cut 5. The chip breaker 2 body inside the cutting edge 4 is provided with a chip-breaking protrusion 6, and the chip-breaking protrusion 6 is gourd-shaped. The utility model utilizes the diamond cutting edge 4 to improve the wear resistance of the tool, and uses laser engraving to carve the chip-breaking protrusion 6 into a gourd shape. The blade is locked to the blade slot of the tool bar through the locking positioning hole 2 and screws.
