Research on the Counter Roller Spinning of Large Thin-walled Cylindrical Parts

The counter roller spinning process is an effective method to form large thin-walled cylindrical parts. By using the internal instead of core mould, may solve problem high cost mould and failure forming large-sized In order study mechanism break through its precision control technology, finite element used analyse effect pass thinning ratio, feed rates, angle inter fillet radius on roundness, straightness wall thickness difference
