Description

Technical Field

[0001] The utility model relates to the technical field of aluminum alloys, and more specifically, to a milling cutter for aluminum alloy high-gloss surfaces. Background Art

[0002] A milling cutter is a tool used for milling, mainly used for cutting materials such as metal, wood, and plastic. The milling cutter can rotate, and its edge has a sharp cutting edge, which can process the workpiece into planes, grooves, curved surfaces, and other shapes. There are many types of milling cutters. According to different uses and shapes, they can be divided into end mills, end mills, round nose milling cutters, ball head milling cutters, etc. The materials of milling cutters usually include high-speed steel, cemented carbide, ceramics, etc., to meet different processing requirements and improve cutting efficiency.

[0003] At present, when processing aluminum alloy surfaces, milling cutters on the market usually use double-edged milling cutters for cutting aluminum alloys. Double-edged milling cutters have two blades, and the two blades are set on the cutter head. When the double-edged milling cutter is installed on a milling machine, the two blades can perform two cuts at the same time. The two blades provide balance during the cutting process and maintain stability when processing aluminum alloys. Double-edged milling cutters are suitable for processing a variety of materials, including but not limited to metals, plastics, wood, etc.

[0004] Because the processing of aluminum alloy surfaces requires higher processing speed of the milling cutter, the double-edged milling cutter may have differences in cutting angles and cutting heights between the two edges during processing, resulting in a slightly rough processing surface; the double-edged milling cutter may not be flexible enough to cause rough cutting when milling some special shapes or sizes. The chip groove of the double-edged milling cutter is small, which may affect the chip removal efficiency. When processing certain materials, there will be problems with waste chip accumulation, which will cause the double-edged milling cutter to overheat, and the two edges of the double-edged milling cutter may wear unevenly, resulting in damage to the milling cutter, which may require more frequent sharpening or replacement.
