Wire drawing process for grinding wire drawing wheel refers to machining straight lines on the surface of parts by means of machine friction. Aesthetics has no standard and is very subjective. The utility model has the dual functions of removing the scratch on the surface of the parts and decorating the surface of the parts. Straight wire drawing process has two kinds: continuous filament and interrupted yarn. The continuous thread can be obtained by a continuous horizontal linear friction on the surface of the part (such as hand grind under the condition of the present device or the brush of a steel wire with a planer in the condition of a present device). Changing the diameter of the stainless steel brush can get different grain sizes. Interrupted silk pattern is usually made on brushing machine or rubbing machine. Production principle: two groups of rotating differential wheels are used, the upper group is a fast rotating grinding roller, the lower group is a slow rotating roll, and the aluminum or aluminum alloy plate passes through the two groups of roller wheels and is brushed out with fine and intermittent straight lines.

Before bending and so on, the drawing wheel is generally a flat drawing process which has a high requirement for the front treatment of the base material, otherwise it will amplify the defect of the base material after the appearance is disposed. At present, there is no evaluation method and standard for drawing aesthetics in the industry, and some customers use roughness measurement to judge.
Now, the appearance of aluminum alloy products is not electroplating, some customers use the microscope to enlarge the observation of drawing process effect. The drawing wheel can only be used as an auxiliary means. After all, the drawing process is a macroscopic overall effect, not the micro effect. It’s a variety of colors that are oxidized. Anodizing has heard that Han Tong lapping against aluminum materials is mainly to strengthen its surface hardness (a layer of ceramic) to enhance its friction resistance. Hot stamping is also a kind of heat transfer. Die casting aluminum parts can be treated by wire drawing process, and then a layer of protective film is sprayed to prevent oxidation. The die casting, of course, can also be treated with surface oxidation. The appearance of a dumb light can be done, but the effect of the grinding is a prophase process of oxidation disposal through the sand blasting process.
