What causes the fracture of high-precision cold-drawn tubes: High-precision cold-drawn tubes are processed by high-precision cold-drawing machines. The finished products are excellent in both quality and performance, and have been applied to exert their due economic benefits. However, in actual production, due to the influence of certain factors, precision cold-drawn tubes may fracture, resulting in certain losses. Therefore, we need to find the reasons as soon as possible and make up for them. Analysis shows that the quality of precision cold-drawn tubes is affected because some manufacturers do not pay attention to product quality and blindly reduce production costs. For example, reducing the number of cold-drawing passes or annealing times will cause the product to fracture, which is also a harmful form of failure and should be avoided as much as possible. Therefore, strict regulations should be made on the production process of precision cold-drawn tubes, and the inspection and supervision of the actual process should be strengthened, so as to effectively avoid and eliminate the occurrence of cold-drawn tube fractures and ensure the safety and stability of their application.
