能获得锻件的高精度尺寸是温锻的优点之一,据某些资料,按经济互助委员会标准СТСЭВ144—75,其精度能够达到8～11级,与冷模锻精度相当。但是,要达到这样高的精度,仅仅在严格稳定的工艺参数、首先是温度参数的条件下才有可能。在生产条件下,锻件的尺寸精度取决于毛坯和工艺过程变化参数,其中包括所采用的工艺系统的刚性(压力机—模具)。 It is one of the advantages of warm forging to obtain the high-precision size of forgings. According to some data, according to the standard of Mutual Economic Cooperation СТСЭВ144-75, the precision can reach 8 to 11, which is equivalent to the accuracy of cold forging. However, to achieve such a high level of accuracy, it is only possible with strictly stable process parameters, above all temperature parameters. Under production conditions, the dimensional accuracy of the forgings depends on the stock and the process variation parameters, including the rigidity of the process system used (press-mold).
