Japanese energy industry is in " person and car science and technology are exhibited " (in May 2007 23 ～ 25 days, pacific Ocean horizontal creek can exhibit a center) on, exhibited to come true through using cold forging technology small-sized light quantified hub component. With the hub component that cold forging craft is machined and becomes, still belong to " the whole world first " (Japanese essence is versed in) . Basically face the driven pulley of small-sized car and medium-sized car. This company uses hot forge craft to machine hub component all the time so. Through using cold forging technology, hopeful depends on the improvement that machines sclerosis and exterior surface roughness to increase strength. Increasing the intensity respect of the flange R ministry that stress centers easily especially, the effect particularly apparent. Because hopeful realizes treatment sclerosis, compare a wall because of this and photograph of hot forge product thick can be able to reduce, make thereby small-sized light quantify become a possibility. Particular treatment working procedure is: Above all will great ability (carbolic steel) the form that processes general hope through cold forging, be opposite again next the place with great difficulty of the treatment when forginging and the place that need precision work have cutting treatment and abrade treatment. Compare with hot forge photograph, cold forging makes material is out of shape hard, and use the end panel with punch small area in order to form flange department " flank punch law " , can reduce a need (of punching machine) figuration bear, solved this one problem thereby. In addition, the advantage that this company still listed cold forging excel to heat up forge -- the appearance precision of figuration product is taller. Accordingly, the working procedure that the cutting treatment that have needs after forginging wants little at heating up forge. Henceforth, this company will recommend the hub component that makes with cold forging craft to each car manufacturer. CNC Milling CNC Machining
