Edge burr up/Customer complained that when a batch of purchased stainless steel flat plates was used, it was found that the burr on the edge was up. Since the customer wants to fold the edge, the burr may damage the processing equipment, so the quality objection is raised. The batch of stainless steel plates purchased by the customer is 304/2B and the thickness is 2.0mm, which is the company's Kaiping flat plate. Generally, the glitch of the tablet is always downward, so check the Kaiping records. After checking the Kaiping records, it was found that the batch of flat plates had normal burrs during unwinding, but due to slight scratches on the upper surface, considering the customer's requirements on the surface that there should be no scratches, the steel coil was turned upside down so that the lower surface was upward. The lower surface of the steel coil is normal after inspection. But because of the unwinding, the edge burr is upward. Due to the small number of tablets, it is recommended that customers polish the edges of the tablets before using them, and give customers a certain amount of compensation. Unwinding is a common method to solve the quality problem on the single surface of the steel coil. However, when using this method, you must also consider the burr problem. Try to ask the customer's opinion first to avoid unnecessary objections.
