Abstract

The invention provides a micromachining method of textures on a metal surface. The method comprises the following steps of: putting a metal base material on a machining face plate of a numerical control machine which has the linkage of an X axle, a Y axle and a Z axle, wherein the X axle controls the left and right movement in a horizontal direction of the numerical control machine; the Y axle controls the forward and backward movement in the horizontal direction of the numerical control machine; the Z axle controls the movement in the vertical direction of the numerical control machine; and a circular cutter head is arranged on the numerical control machine, and a cutter is arranged on an edge of the circular cutter head; and controlling a motion path of the circular cutter head of the numerical control machine, wherein the circular cutter head drives the cutter to cut so as to form a cutting path, the textures can be obtained on the surface of the metal base material by repeating the cutting path, and the circular cutter head performs uniform motion along the horizontal direction in the cutting process when the motion path of the circular cutter head is one of a V type, an X type and a circular arc shape. By the method, various novel textures can be formed on the metal base material, a three-dimensional (3D) effect can be achieved, and the textures have good handfeel.

Description

technical field [0001] The invention relates to a micro-machining method for textures on metal surfaces, which belongs to the field of surface treatment of metal materials. Background technique [0002] During the processing of metal materials, micro-machining methods are often used to form patterns with decorative effects on the metal surface, such as chemical etching, laser engraving, etc. Compared with the above-mentioned chemical etching and laser engraving and other processing methods, the CNC machine tool (CNC) micro-machining method has a high degree of automation, and the processed pattern has a strong three-dimensional effect and a good hand feel. At the same time, it has the advantages of high gloss effect, no pollution, and high production efficiency. However, at present, CNC micromachining mainly forms some simple lines on flat metal materials, or just mills off a layer of the surface to achieve a high-gloss effect. At present, there is no way to obtain complex ...
