1. Wire drawing is a metal processing technology. In metal pressure processing, a silk road effect is produced by rubbing the metal surface with sandpaper under the action of external force. The satin finish has a very strong decorative effect.

2. The processing method of surface drawing is to choose different processing methods according to the requirements of drawing effect, different workpieces, surface size and shape. There are two methods of drawing: manual drawing and mechanical drawing. Common hand-drawn industrial multi-purpose cleaning cloth.

3, abrasive belt drawing is the most traditional drawing method, used for flat drawing, especially suitable for sheet processing. The abrasive belt rotates at a high speed, and the plate is polished and drawn by the conveyor belt through the abrasive belt. Generally, the stainless steel plate, aluminum alloy and other plates are made into a brushed semi-finished product in order to further produce a product using the plate as a raw material. Usually very thin and short, it can be called snow pattern. This method requires that the applicability of the abrasive belt is better, and the line effect of the board can be more uniform. The brushed thread does not have an uneven feel, but the visual impression of the thread is obvious.

4. The specific description of the drawing process is as follows: It is through the surface of the hard abrasive such as sandpaper and grindstone that closely fits the surface of the knife. After being pulled by force, many scratches are left on the steel surface. The depth, direction and uniformity of the scratch are related to the pulling method The depth is related to the thickness of the abrasive mesh, the uniformity and the update of the abrasive and the quality of the abrasive are related. Generally, the lower the mesh number, that is, the rougher the abrasive, the larger the drawing depth, the sharper the overall look, and the higher the mesh number, the shallower the drawing effect. In the case of high uniform mesh drawing, The drawing should have a gray and white uniform reflection, no mess and uniformity. A good drawing should be the same as the satin in a single direction, and the visual effect is uniform. However, in actual operation, manually pulling the abrasive can not achieve perfect uniform strength, so manual It is difficult to achieve perfect straightness when drawing without auxiliary fixtures, and the force controlled by the hand cannot be perfectly uniform, so it is more difficult to achieve perfect drawing than the mirror surface.
