TD75型带式输送机滚筒的轮壳是由A3钢制成的,按图纸要求,其键槽侧面的光洁度为?5,但目前很多厂的工艺水平还达不到这个要求,在同行业的产品质量检查中,这个问题已经成为影响带式输送机产品合格率的一个主要因素。我们针对这个关键,在工艺上作了一些
TD75-type belt conveyor roller shell is made of A3 steel, according to the requirements of the drawings, the keyway side of the finish is? 5, but at present a lot of factories of the level of technology also failed to meet this requirement in the same industry products In quality inspection, this problem has become a major factor influencing the passing rate of belt conveyors. We focused on this key, made some in the process
