一、改用加工中心取得的效果 图中所示是我厂某新产品机床的进给箱体,零件材质为灰铸铁HT20-40。在新产品通过试制后,为了克服使用传统工艺手段加工的困难,降低生产成本,我们把该零件精度相关的精铣工序和精镗等工序安排在我厂生产的XH754型卧式加工中心机床上进行,一次装夹,集 First, switch to the effect of the machining center shown in the picture is a new product of our plant feed box machine, parts made of gray cast iron HT20-40. After the new product passed the trial production, in order to overcome the difficulty of processing using the traditional process and reduce the production cost, we arranged the precision finishing process and the fine boring process related to the accuracy of the part in the XH754 horizontal machining center machine tool produced by our factory Carry out, a folder, set
