The invention discloses a milling cutter. First milling blades and second milling blades are alternately arranged in a plurality of cutter grooves. The first milling blades and the second milling blades all comprise upper surfaces, lower surfaces, a plurality of side faces connecting the upper surfaces and the lower surfaces, and corner faces located between the adjacent side faces. Upper cutting edges are formed by the side faces and the upper surfaces. Upper corner edges are formed by the corner faces and the upper surfaces. An upper cutting unit is formed by any two adjacent upper cutting blades and the corresponding upper corner edge connected with the adjacent upper cutting edges. One upper cutting edge of each upper cutting unit is a main cutting edge, and the other upper cutting edge of each upper cutting unit is an auxiliary cutting edge. When the upper cutting units of the first milling blades and the second milling blades carry out cutting, workpiece cutting-in angles are formed by the upper cutting edges serving as the main cutting edges and the surface of a workpiece, and in the same cutting direction, the workpiece cutting-in angles of the upper cutting edges, serving as the main cutting edges, of the first milling blades and the second milling blades are different. The milling cutter has the beneficial effects of being good in scrap breaking capability, high in machining capability and the like.
Description
technical field [0001] The invention relates to the field of metal cutting, in particular to a milling tool. Background technique [0002] During the milling process of the insert, the shape of the chip has a major impact on the life of the insert and the magnitude of the cutting force. Broken chips can reduce the load on the edge and prolong the life of the tool, and easily broken chips can shorten the contact time between the chip and the upper surface of the blade, reduce the cutting heat of the edge and reduce the cutting force. In order to improve the cost performance of the blade, people put a lot of energy into the shape and groove structure of the blade to achieve optimal control of chips. In the prior art, the chip length of the blade can be controlled by the geometry of the blade, but the width of the chip is usually limited by the cutting depth, that is, it is difficult to meet the requirements of high cutting efficiency and good chip breaking ability at the same...
