In the process of sheet metal processing, especially for processing and production tasks with high precision requirements, the requirements for quality control instruments are very strict. During processing, the deformation of precision sheet metal parts due to non-standard operations will affect the final design accuracy, resulting in product scrap. Finally, the unit price cost of sheet metal processing will increase, and the delivery speed and enterprise benefits will be affected.
1. Sheet metal parts were crushed. The main cause of crush injury is debris on the surface of the material, or debris in the cutter or cutter head turntable, or unreasonable program settings, excessive tool clearance, etc.
Solution: Before processing, the operator should use an air gun or a rag to clean up the debris on the surface of the material and tool. The gap between the lower die and the technician should be reasonably adjusted and selected according to the thickness of the plate.
2 Perform degaussing. Sheet metal parts have scratches. The operator has scratches during the loading and unloading process, or it may be caused by foreign objects in the mold or the material itself before processing.
Solution: If the incoming material has serious scratches, it will not be used. Therefore, before domestic processing, the surface of the sheet must be carefully inspected. At the same time, during the loading and burr grinding process, the sheet metal parts should not be stacked together for polishing, and the workpieces should be placed neatly and flat. The height of each layer should be appropriate, so it is best to prevent the foam layer from being isolated. 3. Deformation of sheet metal parts. The main problem is the adjustment of equipment parameters.
Unreasonably low die spacing can create distortion, so sample handling procedures are critical. At the same time, the quality inspection frequency of the sheet must be very high to ensure that the precision of the processed sheet and the sample is exactly the same. In addition to the cash CNC machining equipment, it is very necessary to improve and standardize the process system and professional team of precision sheet metal processing. Therefore, when choosing a high-quality sheet metal processing manufacturer, we must first check its comprehensive capabilities
