表壳是手表上百个零件中的一个重要部件,它的质量直接影响到手表的外观和装配质量,壳坯是表壳加工的第一道工序,目前国内表壳制坯工艺有热压型、板料冷冲或温冲、冷挤压等。热压型工艺是国内多年来采用的工艺,它最大的优点是省料且切削加工量小。板料冷冲或温冲工艺是最近几年学习了香港制坯工艺,并结合国内的实际情况而 Case watch is one of the hundreds of parts in an important part of its quality directly affects the appearance of the watch and assembly quality, shell shell is the first case processing case, the current domestic case billet technology has hot-pressing type , Sheet cold or warm red punch, cold extrusion. Hot-pressing process is the technology used over the years, its biggest advantage is saving material and cutting a small amount. Sheet cold or warm red process is learned in recent years, Hong Kong billet technology, combined with the actual situation in the country
