With the rapid development of industrial production, the field of sheet metal parts is still booming. What do you know about the professional knowledge of sheet metal parts processing? What are the front and back sides of sheet metal parts? How should we distinguish? The processing factory takes you to distinguish!

how do you understand the front and back sides? The front face is the side facing up when processing is carried out, and the back face is the side facing down when processing. Sheet metal cutting methods include laser cutting, shearing, and punching. According to the standards of fiber laser cutting and high-speed punching machine blanking of its own factory equipment, when laser cutting or blanking parts, small burrs will appear on the lower side of the product board of the numerical control sheet metal processing center after processing. if the surface layer is not smooth, there will be no smoothness and unevenness. this side is the back side, and the front face is naturally the smooth side. In a situation like this, there are many occurrences in the process of aluminum plate cutting and high-speed punching. If one must be polished piece by piece before bending, it will be difficult. However, if one does not polish and put the non-smooth side outside under bending, the appearance will be affected. Therefore, in the process of our processing, when unfolding, unfold and recognize from the reverse side of the part, and when unfolding, it is the front face. The rough surface will roll to the invisible side in the process of bending, and no burr can be seen, thus it is not easy to cause the visual effect to be not good-looking. Another advantage of parts being unfolded in this way depends on the fact that the bending position has been clearly defined before the sheet metal parts are processed, thus saving effort, time and labor, and paying attention to burrs during bending.
