The main features of CNC flanging machines without molds include: ‌Save equipment costs and improve production efficiency‌. This type of flanging machine does not require molds for flanging, which saves the cost of mold purchase and maintenance. At the same time, since there is no need to change the mold, CNC technology is used for control, which greatly saves debugging time and improves production efficiency‌1. In addition, CNC flanging machines without molds also have the following characteristics: ‌The system has a molding preservation function‌: This eliminates the waste of the first piece and makes production more efficient and economical‌1. ‌Wide processing range‌: The diameter range of the equipment can be customized according to customer needs, which greatly increases the utilization rate of the equipment. At the same time, this type of equipment usually has a variety of functional configurations, such as inner rotation, outer flanging, inner flanging, punching, bell mouth, etc., to meet the needs of different customers‌1. ‌Easy operation‌: CNC flanging machines usually use PLC operating systems or similar advanced technologies to make operation easier and more intelligent. Ordinary people can perform one-button operation, which is easy to learn and understand‌2. ‌High processing precision‌: Due to the use of CNC technology and high-precision control systems, CNC flanging machines without molds usually have higher processing precision and stability, ensuring the consistency of product quality‌3. In summary, CNC flanging machines without molds have the characteristics of saving equipment costs, improving production efficiency, wide processing range, simple operation and high processing precision. They are one of the important equipment in modern production.
