xiehe model

There are differences in shape and structure when the hand model is polished. If the shape is not very special, there is not much difference in the finished product when the surface is processed. When grinding, you can use some relatively coarse sandpaper for simple grinding, and remove some of the thicker burrs on it for more detailed grinding. When the product has different requirements for the surface layer, the degree of grinding treatment can be different.

After the polishing is completed, spray some putty. The advantage of this is that the original roughness of the surface of the product can be more obvious, and the problems existing in the product can be seen more clearly. In this way, the correction will not be too blind, and it will be carried out in a targeted manner until all the polishing of the product is completed. So do you know what is the function of hand grinding? Next, the Xiehe prototype processing factory will give you a brief introduction.

The polishing process has three main functions:

1. Enhance the adhesion of the coating: Before spraying the new paint film, the old paint film layer after hard drying is generally polished, so there will be phenomena such as smooth surface transition and poor adhesion, so the coating can be enhanced after grinding. mechanical adhesion.

2. Substrate: For the substrate, it is mainly to remove burrs, oil and dust on the surface of the substrate.

3. Scratch the putty surface: Generally, the surface is relatively rough and needs to be sanded to obtain a relatively flat surface. Therefore, grinding can reduce the roughness of the workpiece surface.

Grinding the hand model is definitely not a superfluous job, it can effectively clean up the impurities on the base material; in addition, if some materials are scraped with putty, most of the surface will be relatively rough, after grinding It can make its surface smoother and reduce the roughness of the workpiece; moreover, the material after grinding can make the coating adhere better.

When producing prototype products, the prototype model must be polished. After processing a certain part with a machine, it is difficult to avoid some burrs or marks on it. When dealing with such problems, it needs to be solved manually. In general, polishing paste is used for polishing, and sandpaper is also used for polishing. In this process, the effect of polishing treatment can also be checked by spraying dust.

The above content is the role of hand polishing, I hope it can be helpful to everyone. If you want to know more about Xiehe rapid prototype processing, please call the Xiehe rapid prototype processing factory, we will serve you wholeheartedly.
