tzinHigh precision requirement for ring rolling machine will limit productivity and have high cost, therefore, sizing process after ring rolling not only increase precision of machining parts but only decrease requirement for ring rolling machine, that increase process comprehensive economic and technical level.
Sizing after rolling process can decrease roundness, taper degree and PZJ250diameter size error greatly to improve precision further.
