Introduction to Stainless Steel Ball Metal Spinning Method
The stainless steel ball metal spinning method is an advanced and chip free processing method, belonging to a new branch of pressure processing. It integrates the process characteristics of forging, extrusion, rolling, and rolling, and has a high material utilization rate (up to 80-90%), saving a lot of processing time (1-5 minutes for forming). After spinning, the material strength can be doubled. Due to the small area contact between the spinning wheel and the workpiece during spinning, the metal material is subjected to biaxial or triaxial compressive stress, which makes it easy to deform. With relatively low power, a high unit contact stress (up to 2535Mpa) can be obtained. Therefore, the equipment is lightweight and requires less total power (less than 1/5-1/4 of the press). It has been recognized by the foreign valve industry as an energy-saving ball processing technology solution and is also suitable for processing other hollow rotating parts. Spinning technology has been widely applied and rapidly developed abroad, with mature and stable processes and equipment, and achieving automatic control of mechanical, electrical, and hydraulic integration. At present, spinning technology has also made significant progress in China and has entered the stage of promotion and practical application
