Abstract
The invention relates to a four-edged unequal partition milling cutter. The four-edged unequal partition milling cutter comprises a cutter rod and a cutter head, the cutter head comprises a first cutter edge, a second cutter edge, a third cutter edge and a fourth cutter edge, the included angle of the first cutter edge is same to the included angle of the third cutter edge, the included angle of the second cutter edge is same to the included angle of the fourth cutter edge, the included angle of the first cutter edge is different from the included angle of the second cutter edge, the anterior angles of the four cutter edges are same to each other, the clearance angles of the four cutter edges are same to each other, and four helical angles of the cutter edges are same to each other. The included angle of the first cutter edge is 93DEG, and the included angle of the second cutter edge is 87DEG. The anterior angle, the clearance angle and the helical angle of each of the four cutter edges are 4DEG, 5DEG and 42DEG respectively. The four-edged unequal partition milling cutter adopting the above structure effectively inhibits the cutting resonance phenomenon generated during metal machining to realize stationary cutting.
Description
technical field [0001] The invention relates to a milling cutter, in particular to a four-blade unequal split milling cutter. Background technique [0002] End mills are mainly used in the production and processing of high-speed CNC machine tools in IT, molds, medical equipment, aerospace, military equipment and other high-precision accessories. The existing four-edged end mills have four slots, and each slot is designed to be equally divided , the cutting edge of each groove is the same, this kind of end mill has the same spiral groove pitch, so it is easy to generate resonance in the process of cutting metal, which affects the quality of the machined surface. Contents of the invention [0003] The purpose of the present invention is to provide a high-efficiency, stable cutting four-blade unequal split milling cutter. [0004] The technical scheme that realizes the object of the present invention is as follows: [0005] A four-blade unequal split milling cutter, includi...
