Embodiment Construction
[0025] The present invention will be further described in detail below by referring to the accompanying drawings and by describing the embodiments.
[0026] The present invention includes a cutting insert 1 and a cutting tool using the cutting insert 1 .
[0027] Such as figure 1 As shown, the cutting insert 1 of the present invention has an overall approximately diamond-shaped one-piece body construction, the cutting insert 1 has opposing top surfaces 2 and bottom surfaces 3, and four side surfaces extending between the top surfaces 2 and bottom surfaces 3, They are the opposite first side 4 and the second side 5, and the opposite third side 6 and the fourth side 7, respectively. The top surface 2 and the bottom surface 3 of the present invention are parallel, both are horizontal straight surfaces, the length of the top surface 2 is greater than the length of the bottom surface 3, and the width of the top surface 2 is the same as that of the bottom surface 3. In the present...

The invention relates to a cutting insert and a cutting tool, comprising a top surface and a flat bottom surface, and four sides extending between the top surface and the bottom surface, which are respectively opposite first side and second side, opposite third side and The fourth side, wherein the first side and the fourth side are connected by a circular arc transition part, the edge where the top surface intersects with the fourth side forms the main cutting edge, and the extension line of the edge where the top surface intersects the arc transition part forms a smoothing The edge where the top surface intersects the first side is formed as a secondary cutting edge, and a chip flute is formed on the top surface adjacent to the main cutting edge, and the chip flute includes a straight section connected to the main cutting edge and a flat The straight segment is connected to the arc segment, and the straight segment and the arc segment of the flute form a smooth transition together with the secondary cutting edge, the wiper edge, and the arc transition part to define a curved surface extending to the upper side of the chip flute. The cutting insert is fixed in the cutting tool by rotating it through 30 degrees.
Description
technical field [0001] The invention relates to the field of metal processing machine tools, in particular to a cutting insert for processing aluminum alloys and a cutting tool using the cutting insert. Background technique [0002] In the production and scientific research and trial production of petroleum tools, a large number of aluminum alloys need to be processed from blanks to finished products at one time. The rapid development of CNC lathes provides powerful conditions for refined one-time forming. There are a large number of comprehensive cutting processes such as rough turning, semi-finishing turning, and finishing turning in the process. Therefore, from the blank to the finished product, the cutting amount is from large to small, and the load and cutting parameters are constantly changing. New challenges are put forward for the adaptability of the tool. test. At present, while maintaining a stable cutting efficiency, the domestic aluminum alloy cutting tools adop...
