在机床零件中,供操纵用的手把常占有一定的数量,其形状根据用途和所在位置而多种多样。为了减少机床的设计工时,许多广泛使用的手把已经标准化,这样便给制订此类零件的工艺带来了有利的条件,并为此类零件工艺典型化创造了基础,从而也就可减少加工此类零件的工艺装备的设计和制 In machine tool parts, handles for manipulating often occupy a certain amount, the shape of which varies depending on the purpose and location. In order to reduce machine design time, many of the widely used hand grips have been standardized, thus providing favorable conditions for the process of making such parts and creating the basis for the typical process of such parts, thereby reducing the need for machining The design and manufacture of the process equipment for such parts
