In the process of aluminum sheet shearing, aluminum sheet manufacturers should pay attention to the following points:
1: Scratch phenomenon: Scratch phenomenon is a relatively common phenomenon in domestic shearing. In domestic production of aluminum plate advancing shearing machine, it will rub against the feed port of the shearing machine and cause scratches, which affects the appearance quality of the
aluminum sheet . If the user who has high requirements on the quality of the board surface is recommended to be sheared after coating (surface coating, protective aluminum plate), usually the cost of coating is 2 yuan/square meter.
2: The size is accurate: the length and width should be accurate and reasonable, and the diagonal tolerance should be controlled between 1-2mm. Of course, the cutting of small-size
aluminum sheet cannot be controlled so precisely.
3: The trimming is neat: the cutting edge of the aluminum sheet is not neat due to the lack of sharpness of the cutting blades of some shears. It is recommended to look for large processing enterprises and new processing equipment during processing. The above points are easy to appear in the cutting process, and the most important is the accuracy of the size.
