我们在加工中,遇到图1所示铝矩形拉延件切边,通常采用冲模切边或铣床切边。由于该零件尺寸大,数量仅一万件,若采用冲模切边,需要制造一副大而结构复杂的模具,不仅成本高,而且周期长。若采用铣床切边,由于零件材质软,被铣切的边缘易变形,同时效率也低。为此,我们采用车床车边工艺方法。 We are in the process, we encounter the aluminum rectangular drawing parts shown in Figure 1 trimming, usually using die trimming or milling machine trimming. Due to the large size of the part, only a few ten thousand pieces, if the use of die cutting, you need to create a large and complex structure of the mold, not only high cost, but also long cycle. If using milling machine trimming, due to the soft parts of the material, the edge being milled easily deformed, while the efficiency is low. To this end, we use the lathe edge process.
