锻压加工工艺,目前正朝着使其制品尺寸、形状完全或接近成品的尺寸、形状的方向发展,以期不再经过任何切削加工。用锻压加工制出的零件精度和表面光洁度已达到了相当的水平(表1),它已经不再只是毛坯的制造了。 由表1可见,锻压加工方法在精度方面所获得的成绩将彻底改变人们对它 The forging processing technology is currently being developed toward the size or shape of its products completely or close to the size and shape of the finished products so as not to undergo any machining. The accuracy and surface finish of the parts produced by forging have reached a considerable level (Table 1). It is no longer just the manufacture of blanks. From Table 1, it can be seen that the score obtained in forging processing method will completely change people’s performance on it.
