Spinning process

     Fixing the flat blank or the pre-formed blank to the rotating mandrel, applying pressure to the blank by the rotating wheel, and simultaneously feeding the rotating wheel in the axial direction, after one or more processing, obtaining various thin-walled hollow rotating products. Process method. Fixing the flat blank or the pre-formed blank to the rotating mandrel, applying pressure to the blank by the rotating wheel, and simultaneously feeding the rotating wheel in the axial direction, after one or more processing, obtaining various thin-walled hollow rotating products. Process method (see picture). When spinning, the contact area between the rotating wheel and the blank is small, the processing material is only partially plastically deformed, and the deformation resistance is small. The large-scale product can be processed by small tonnage equipment, and the hollow cone, the cylindrical part, the hemisphere and the thin are manufactured. An effective method for precision products such as wall pipes. Spinning products have high precision, good mechanical properties and a wide range of sizes. Spinning tool molds are simple and easy to replace; for some products, production costs are lower than other methods. The main disadvantages are long production hours, low production and limited varieties. Suitable for the production of small batches, multi-variety products.
