钛合金做手表壳体与其它传统材料不同，成形时变形抗力和弹性回复大，热导率低，因此使用冷锻或切削等现行加工方法难以加工，增加了制造成本。传统的生产方式要通过反复试验来确定预成形模的形状，选择合适的锻造条件等，生产准备时间长．为适应钛表壳的生产特点，缩短生产周 Titanium alloy watch case is different from other traditional materials, forming deformation resistance and elastic recovery, low thermal conductivity, so the use of cold forging or cutting of the current processing methods difficult to process, an increase of manufacturing costs. The traditional production methods to determine the shape of the preform by repeated testing, select the appropriate forging conditions, production preparation for a long time. To meet the production characteristics of titanium case, shorten the production week
