Sheet metal processing is a common method in the processing industry. What should be noted during the precision sheet metal processing process?

During the precision sheet metal processing production, staff must first learn the relevant processing techniques to ensure the quality and precision of the material processing. During processing, operations such as cutting and stamping can be completed, and after these processing procedures, the production goal can be achieved. Staff also need to pay attention to mastering parameter characteristics and processing methods during daily production, which are important aspects that cannot be ignored.

2. Regarding material, it is crucial to carefully verify aspects such as board thickness and tolerance; for special angles, the inner radius of the bending angle should be trial-bent first before deciding whether to unfold; emphasize key areas prone to errors, and be meticulous during the process.

3. During precision sheet metal processing, it is essential to consider tolerance dimensions reasonably: negative tolerance to the bottom, positive tolerance to half; the hole dimensions are the opposite of the tolerance dimensions; pay attention to burr direction; draw section views for positions such as threading, riveting, tearing, and forming bosses.

4. Larger areas require zoomed-in images to prevent errors and omissions; designated areas for painting protection should be marked; in sheet metal processing, the unfolding method should be reasonable, balancing material savings with workability; appropriately select gaps and edge wrapping methods, with gaps of 0.2 for T below 2, and 0.5 for T between 2-3, typically wrapping long edges over short edges.

5. During the bending process of precision sheet metal processing, it is necessary to acknowledge the bending direction and the bending size. If there is excess or insufficient material, adjustments should be made promptly. Once all acknowledgments are completed, mass production can begin. Then, during the mold replacement and work process, it is essential to conduct a re-inspection.
