Description

Technical Field

[0001] The utility model relates to the technical field of milling cutters, in particular to a milling cutter for machining controllable roughness. Background Art

[0002] Milling cutters are cutting tools that are usually used in milling machines or processing machines to perform milling operations (sometimes in other machine tools). They remove material by their fixed feed rate in the machine. There are many types of milling cutters, among which face milling cutters are shaped like a tube (but with thicker walls) and have blades around and on the sides of the body. When used, milling is completed by the blades.

[0003] The prior art patent document with publication number CN111531214B provides a milling cutter for machining controllable roughness, which relates to the field of milling cutters, including a cutter disc and a plurality of mounting ends fixed to the side surface of the cutter disc, the mounting end being provided with a fixed side surface; a blade mounted on the fixed side surface, which is in the shape of a right prism, and the side surface of the right prism is divided into a rough surface and a smooth surface by the edge of the bottom surface, and the blade includes at least one smooth surface; a breaking edge, among all the blades in a cutter disc, at least one blade has a breaking edge in its rough surface, before machining parts, the roughness requirements of the parts to be machined are determined first, and then the corresponding breaking edge is selected, and the blade with the breaking edge is mounted on the fixed side surface of the mounting end head, so that the rough surface of the blade with the breaking edge is facing the machining position of the parts, so that during milling, not only can the material of the parts be removed, but also the surface of the parts after milling can meet the roughness requirements of the design through the breaking edge, thereby saving the machining process.

[0004] However, during the use of the existing milling cutters for machining controllable roughness, although the required roughness can be machined at the machining position of the workpiece through the breaking edges of different shapes, the cutting edge of the milling cutter needs to be adjusted during machining. During the adjustment, tools are needed to disassemble and adjust the milling cutter, which makes it inconvenient to adjust the milling cutter. For this reason, we propose a milling cutter for machining controllable roughness. Utility Model Content
