Description

гуры мастер-пуансоном, нредварительно нагретым до температуры выдержки штамповой заготовки. После завершени  процесса формообразовани  рабочей фигуры штамповую заготовку подвергают полному закаливанию от температуры деформации, отпуску, если он требуетс , и передают на механическую обработку .gury master punch, preheated to the holding temperature of the die stock. After the process of forming the working figure is completed, the die stock is fully hardened from the temperature of deformation, tempering, if necessary, and transferred to mechanical processing.
